Judging by the information you've kindly supplied, if I had a cab where the roll-off didn't start until about 50-60Hz, I should notice a difference in the 2nd harmonic. Is there anywhere where I can find the specs of mass produced cabs? Or a guide to how I could make a 1x15 cabinet that performed well down to 50Hz?[/quote] If you think you can make a cab, Bill Fitzmaurice designs will probable have something to suit. I'd recommend you consider the Omni 15 as a simple build which will do what you want. [url="http://www.billfitzmaurice.com/Omni15.html"]http://www.billfitzmaurice.com/Omni15.html[/url] I am taking an Omni 12 to the north west bass bash in March if you can wait that long.

Sennheiser HD485s - sound good, and carry bass well. I chose them by taking a personal stereo into a hifi shop. The 485s were the furthest up the Sennheiser range I could go without running into sensitivity problems. The next ones up distorted on my personal stereo, but not on a mains amp. The next ones down did not sound as good. The only problem with them is that you cannot get a shorter cable for them; a 1m cable would be useful for use with waist or belt mounted units, e.g. Pandoras etc.

An option that has not been mentioned yet is a cheap 4 string back-up tuned BEAD on the basis that you use the B string a lot more than the G. With regard to the "I'll borrow someone's bass" brigade - would you lend a stranger your pride and joy? There have been threads on this before.

[quote name='Clive Thorne' post='125634' date='Jan 22 2008, 06:42 PM']I'm sure I've seen these discussed in a thread before, but a search for rocket did not reveal it (perhaps it was on bass world). Anyway, I'm doing a lot of traveling and spending nights away from home at the moment, so am looking for something portable (ie fits inside the bass case) to go between my bass and the headphones, preferably battery powered. The Pocket Rocket is one that springs to mind, but a few reviews on the 'interweb' mention excessive hissing. Does anyone have experience of these or equivalent devices, and if so what are your thoughts/recommendations? Thanks in advance people, Clive.[/quote] I have to start by saying that I am biased - I have a Pocket Rock-it to sell, but I took it off the market just before Christmas [url="http://basschat.co.uk/index.php?showtopic=8475"]http://basschat.co.uk/index.php?showtopic=8475[/url] They come with headphones which sound fine, - it is only when you upgrade to Hifi headphones that the hiss can get intrusive. They are designed for Fender-type angled jack sockets, and if you have an edge mounted socket, they tend to turn themselves upside down because they are slightly top heavy - not a big deal, but an annoyance just the same. The range of tones is good: practising with chorus sounds really nice, and you have the option of connecting a CD/MP3 player/drum machine to jam along with. I upgraded to a Korg Pandora, which does more, and costs more. I'm looking to sell my Pocket Rock-it for £25 +p&p, and you won't find anything better, new, at that price. Second hand, for the same kind of money, something like a Zoom BFX 708 will give you a headphone output, and a tuner, and a rhythm generator, but it doesn't come with headphones, and it is a lot bigger. For even more money, you might pick up a CD playing Tascam bass trainer. The Mk I does not have a drum machine, but the Mk II does (I think). They are bigger and heavier, and need a PSU and a wall socket. In summary, if you want something small and basic, a headphone amplifier would be good, and there is one readily available. If you want more facilities, it will cost you. If you are interested in the Pocket Rock-it, make me an offer.

The original transistor designs, with bipolar devices, let more current through as they heated up, so in a high powered amp you could get yourself into a destructive cycle where it runs hot, so it lets more current flow, so it runs hotter... then it burns out. MOSFETS let through less current as they get hotter, so they do not go into thermal run-away, and they have become the industry standard for high powered amps. Interestingly (for geeks) bipolar transistors have a smaller voltage drop accross them than mosfets do, leaving more voltage available to push current through the speaker, so for a supply of +&- x Volts, a mosfet amplifier will be less powerful than a bipolar one.

I am interested in adding an on-board preamp to a Corvette, and most of the circuits I have seen fall into one of two camps. a.) An active circuit coming between the pick-up and the pots b.) An active circuit coming after all the pots What difference does it make to the sound of a passive pick-up if you feed it into a hi-z buffer instead of the track of a 250K pot?

[quote name='Beneath It All' post='117308' date='Jan 9 2008, 06:47 PM']Reading music is pretty much like reading the written page - If you analyze what's actually happening,you'll realise that to make a sentence flow, you need to read ahead[as any reasonable reader automatically does]...Great readers tend to read further ahead than average readers; I work with lots of players who read up to EIGHT bars in front[dependent on how tricky the chart is]...I can manage two bars ahead, which seems to be enough...For anyone learning to read music, I would highly recommend starting with a drummers guide to basic rhythms - once you've got the hang of that,reading the actual notes is much less daunting..Good Luck[/quote] Thanks for your input, but I think we're talking about different things, although I have to say my reading probably has this problem too. I read the part and learned all the given variations of notes for each chord in each bar. What I am now trying to do is play them (and others that come to mind) without the page, and without too much repetition, or too much jumping around to avoid repetition. Where I fall off it is usually because I have not thought about which root note I am aiming for, so I try and do it all after '4and', and it doesn't sound too good.

I'm not sure where to start on this, it could be a long post if I gave you all the back story... I have recorded myself improvising over a Band-in-a-box 1451 backing track with its bass muted, using that original bass line and variations as my building blocks. My timing and intonation are a bit shaky, but I am confident that they will improve with practice. Where I stumble, my analysis is that my mistakes tend to be on the 1 beat because I don't look far enough ahead. My plan is to work on that track, building up the speed as I get better, and then move on to other chord sequences, other keys, and other rhythms. I wondered if there are any specific exercises that anyone can recommend that have helped them plot a course through a chord sequence, or does it just come with practice?

Slightly off-topic, but still relevant (I think) - I recently parted from my bass teacher because he attributes my lack of progress to a mental block, which he thinks is is my problem, not his. For the past ~3 years, I have approached bass playing as a series of challenges, and having visited that aspect of melody/rhythm/harmony, and understood it, I have parked it and moved on to the next challenge. My teacher did not pick that up. The current position is that I know quite a lot, but given a chord sequence, and a song style, my first attempt is a stagger-through, rather than a competent bass-line. From my perspective, some people need to be lead by the hand (in my case, guidance on how you incorporate it into your style), and some people need a guru, who gives general direction and they work out the rest themselves. I think it is easy to condem the 'other teaching method', when both are equally relevant.

[quote name='Perry' post='110662' date='Dec 29 2007, 07:57 PM']One of my basses is a Warwick Covette in Bubinga. I really like the look of the same bass in Ash. What's the difference in the sound?[/quote] A bit off-topic, but I have a Bubunga 4-string fretless Corvette, and auditioned the Ash-bodied 5-string version before buying one. It still has plenty of the Warwick sound, but is a lot lighter. However, on a 5-string, that means it is not as well balanced. If you are thinking of a Warwick, check it out with a strap before you buy.

[quote name='TimmyC' post='105486' date='Dec 17 2007, 06:53 PM']Does the Pandora PX4D have a 1/4" jack output? On their site it says "Output: line/headphone dual-purpose output (stereo phone jack)" but doesn't specify the size?[/quote] The casing and front panel markings are the same as the previous versions, so I am pretty sure you will find it has a mono 1/4 instrument jack, a stereo 1/4 inch headphone/output jack, and a CD/MP3 player 3.5mm jack. The PX4B is bass specific, and includes a drum machine which allows you to chain drum patterns together. The earlier Bass and guitar PX4_, had the bass player losing out. For example, the drum kit dropped a lot of drum machine sequencing, and added a 'rule-based bass-part generator'. Having said that, I am using the bass generator on Band-in-a-Box to give me ideas for lines to play, so that function may still be useful to you. The new PX4D model appears to put back in some of what they took out before, however, without a pdf manual, I am not sure how versatile those functions are.

[quote name='stevebasshead' post='103473' date='Dec 12 2007, 06:13 PM']Quite some time back I did the same to my old cheapy. I buggered it up so bad that even the proper allen key had no effect. I thought it was a gonner but I managed to tightly wedge a flat bladed screwdriver into what was left of the two best corners and off it came. I think the reason that worked when the correct sized allen key didn't was because of the taper on the screwdriver blade, I was able to truly wedge it into the corners whereas the allen key had just enough slack to slip out and onto the rounded parts. On mine it was simply a replacement of the allen fitting rather than the entire rod. It was just a small barrel affair that pressed against the end of the neck pulling the rod which was secured at the opposite end of the neck, if you see what I mean. You should be able to get spares from Allparts or Stewmac, but ask your local luthier if he's got any spares. You might just get given one free gratis if you're lucky! Hope this helps, Steve.[/quote] Thanks - there is hope yet.

I have a Yamaha RBX 765, and I though I had a suitable allen key to adjust it. Unfortunately it was too small, and twisted round in the socket, rounding the edges of the hex hole. Firstly, if I get the right allen key, am I likely to be able to use it, since the chewing up of the socket would have been the flat area, not the corners, and secondly, if that fails, how much of the truss rod needs to be replaced, and is that an 'unbolt it' job, or a 'take the fretboard off' job

In 1970(?) as a folky guitarist, and wannabe bass player, I made my first bass as a project at school. The body was blockboard (inch thick pine planks with a veneer each side to keep it together. The neck was teak. It didn't have a truss rod, and it was ever so slightly neck heavy. The fretboard was black formica, as was the pickguard. Pickups and tuners were shop bought, and the bridge was one piece of mild steel, bent to be vertical (bridge) at one end, and sloping (string ball catcher) at the other. Intonation was - measure, drill and screw it on. String height was - it's too high, I need to grind some more off the bridge. With hindsight, I don't think those teachers were particularly musical. Believe it or not, it worked, and I was able to play The Equals - Baby come back - through my dad's Hifi sytem, a Vortexion valve amp and Wharfdale speaker in a corner mounted reflex enclosure. I eventually sold it for the cost of the parts. About 30 years later, I decided to try again, and bought a Yamaha BBN4.

[quote name='G-bitch' post='84912' date='Nov 7 2007, 01:55 PM']I doubt there's any hard and fast rules but I should imagine that the moment you start declaring your income from gigs and have to list your profession or second-job as 'musician' then you are going to have to get professional cover. On the plus side, it goes down as deductable expenses in that case![/quote] I play in a church worship band, and do not (yet) play anywhere for money. When I asked my insurers about covering all my gear while it was being transported, they said - no problem, just list your second occupation as musician, to justify having the gear in the car.

[quote name='Adam.M' post='86529' date='Nov 10 2007, 05:02 PM']I'm looking at the Ashdown MAG 300 head, but i really need something i can use with headphones too from time to time... So i'm looking at that line out, and thinking can i use that for headphones directly OR going into my Hi-Fi and then into headphones that way? I'm guessing i'd still have to have it hooked up to a cab, even if the volume was on zero... not sure about that, i'm still used to all-valve amp's. I've done something like this before but the sheer wattage power of these amp's scare me a bit It's a shame the Marshall MB is such an eye sore, never seen anything so ugly! it has all the features I'd need but I would have to put a paper bag over it to live with it. -Adam.[/quote] The general feeling is that you shouldn't run any amp without a speaker attached, although I am not sure why that would affect a transistor output design. Also, the line out will give you a signal, that would suit your hifi, but doesn't give enough current to drive a set of headphones. Your cheapest options are - 1) buy a S/H practice headphone amp - £20-30 2) buy something like a S/H Zoom 708, which will drive headphones and includes a tuner and a drum machine, and 15 zillion effects that you will never use. - £30-40 3) buy a small S/H mixer, like a Behringer 502 or 802, which will drive headpones, and allow you to mix in your CD player etc. - £20-30

[quote name='Mottlefeeder' post='60351' date='Sep 14 2007, 12:31 PM']There is a growing band of Basschatters who have built Bill Fitzmaurice speaker designs, and are pleased with the results. There is also a band of Basschatters who would not buy something they had not played or played through. This thread is an attempt to bring both groups together. If you have built (or bought someone else's) BFM design, and are happy to talk about it, and allow others to try it out, please use this thread to tell people what you have, and the county or town in which you live. It would also be useful if you gave details about whether you would prefer to meet at a gig, a rehearsal room, or at home, and a rough indication of your availability, e.g. evenings and weekends only, etc. Mentioning whether you use speakons, jacks, 4mm plugs, or any other connector might also be a good idea. If anyone wishes to audition your gear, they should PM you, and between you, you sort out the date and venue. Please do not use this thread to ask technical questions about BFM designs. There is a forum on Bill's website for that - [url="http://www.billfitzmaurice.com/"]http://www.billfitzmaurice.com/[/url] To start the ball rolling, I have an Omni 12, and I live in the Warrington area, and I am around evenings and weekends. The cab is based in a church, which is available some evenings, or I can bring the cab home relatively easily. My amp and speaker are both jack based. There is a review here - [url="http://billfitzmaurice.com/phpBB2/viewtopic.php?t=3324"]http://billfitzmaurice.com/phpBB2/viewtopic.php?t=3324[/url] The Omni 12 goes deeper than an Omni 10, but has three speakers and a crossover, which puts the price up a bit, however with a dedicated midrange unit, the clarity of the mids is stunning. It can also be built as a two way design, and mine is switchable to be 2 or 3 way.[/quote] The aim of this tread was to provide a list of cabs that could each be heard at several locations. It obviously isn't working. If you are still thinking about whether to post here, please do so in the next week. If we do not get a better representation, I will ask the Mods to remove the glue.
