[quote name='Happy Jack' post='138779' date='Feb 12 2008, 12:16 PM']Guys, I'm crap at electrics and such, but pretty good at numbers. I thought the amount of air a speaker could move was driven essentially by the area of the speaker, using the classic PI x r-squared formula. Since PI is a constant, the relative air-moving capability of different speakers should be: 10" = 5.0x5.0 = 25 12" = 6.0x6.0 = 36 15" = 7.5x7.5 = 56 18" = 9.0x9.0 = 81 Crudely, therefore, a 210 will move nearly as much air as a 115. I was perfectly happy with this analysis, it all made sense to me, and it seemed to chime with my own experience. Then I read this on the Ampeg site with reference to the SVT-410HLF: [i]The SVT-410HLF actually moves 10% more air than two 18-inch speakers, and 25% more than three 15-inch speakers![/i] What am I missing here? [/quote] The area of a typical 10" driver is 350cm2, 15" = 856cm2. Therefore four tens =1400cm2 and three 15s = 2568cm2, nearly twice the area of the 4x10. I seem to be missing something too... Reminds me of how suspicious I was of Ampeg's claimed frequency response stats. edit: of course, yes, it does depend also on Vmax but it's a bit sneaky of Ampeg to compare their 10" with a good Vmax with that of a Brand X 18" that just happens to have a tiddly Vmax

I love these stories, hearing that not all megastars are vain and affected. I guess if I was a 'celeb' I'd be happy to meet people who didn't know who I was. I read somewhere about a chance meeting - been trying to find the original article but it's long gone so here's what I remember: Matey lives on a houseboat and is cruising on River X...night is falling and he needs to moor. There are big houses with lawns down to the river. A scruffy bloke greets him, they exchange pleasantries and Matey says: -I know this is a bit cheeky but could I moor here for the night? -Sure, no problem, come and get a cup of tea. Anyway, they become friends (I'm starting to feel like Simon Bates here) and Matey often passes by on the river. One time they go down the pub and Matey notices that there's a bit of a buzz, everyone seems to know Scruffy though few talk to him. Scruffy seems unaware of this. Eventually after his fifth pint Matey goes to the bog and the bloke pissing beside him says: - So how long you known Jimmy Page then?

[quote]I reckon it's only a matter of time before some company sticks magnets around the outside of the lead at each end and claims that the magnets "align the electrons in the signal path, reducing loss of energy through random scatter thus increasing the top end, reducing muddiness in the middle range and allowing the bass frequencies more headroom"[/quote] I'd be surprised if someone hadn't already done that.

[quote name='bass_ferret' post='138456' date='Feb 11 2008, 08:31 PM']It usually means connect in the direction of the arrow, e.g. bass ---> amp ---> send ---> return ---> cab etc. Sometimes in hifi world it is indicated by the writing on the cable.[/quote] Stop me if this is heading in the direction of audiophile shouting and posturing, but directional cable is a nonsense which can be explained by marketing departments but not by the laws of physics. Whether it's bass>>>amp or amp>>>cab, the current is AC which means it goes both ways down the cable. Fortunately we don't seem to have as much bullshit aimed at us as audiophiles do - some of the stuff they will buy is jaw-dropping. CD demagnetiser, anyone?

[quote name='BassBod' post='138403' date='Feb 11 2008, 07:00 PM']Its got mysterious plastic boxes near each plug and its labelled "guitar/amp" at either end because its supposed to sound better if used in the right direction. Or they think we're stupid and will forget where to put the other end. It does sound slightly "fuller" and "brighter" at home, with nothing else but amp hiss to listen to...but in any real world environment I couldn't tell the difference.....and its going to get stepped on and covered in beer just like every other cable. Anyone want it? BB[/quote] Nah, got enough snake oil and antigravity devices ;-)

[quote name='BOD2' post='137188' date='Feb 9 2008, 05:54 PM']You can't run two amp channels into one cab [i][b]unless[/i][/b] there are two or more speakers in the cab that have been wired up independently of each other (so you're effictively connecting to separate speakers that happen to be in the same enclosure). Don't be misled into thinking there's a direct relationship between amp power and loudness - it's really not as simple as that. An efficient speaker with a high Sound Pressure Level (SPL) will be louder than one with a lower SPL even if you put more power into the less efficient one. As a general guide, you need approximately 10 times (yes TEN) the amplifier power to get twice the volume. So, for example, changing from a 250 W amp to a 350 W amp is not going to make a huge difference.[/quote] All that is true; it is also true that an amp designed to give full power into 4 ohms will nearly always give much more than half its rated power into 8 ohms.

[quote name='bilbo230763' post='138053' date='Feb 11 2008, 11:18 AM']I can accept this in principle but my question is this: can a cable effect tone in a manner that impacts significantly on the perceived tonal results in the context of the other environmental variables in play? Or, in English, is the effect significant enough to be heard against the other things that effect it such as the shape of a room, the amp's/bass's eq, flat surfaces, carpets/tileds floors etc. My perspective is that it probably doesn't so, whilst it is worth noting, it ain't worth lying awake over. I am open to challenge.[/quote] A cable can certainly and measurably affect the top end, more so with passive instruments that have high impedance pickups (but even active giutars with pots on the outputs will be affected if the pots are set at less than full on). It's down to the capacitance of the cable, which should be as low as possible. The resistance is irrelevant, so beware of claims like 'oxygen free copper for maximum conductivity' which are just hype. Van Damme cables are good, not all manufacturers publish capacitance. I have swallowed the Little Book Of Calm.

Daflewis just sent me a Virtualizer. It was beautifully packaged, in perfect condition, and arrived the day after we agreed the sale. Chapeaux!

[quote name='alexclaber' post='135834' date='Feb 7 2008, 04:06 PM']The 3015LF has so much Xmax that overexcursion below the tuning frequency is unlikely and the extra sensitivity and power handling in the critical 50-100Hz area should be useful. If you're bored you might like to try shorter ports and see if your experience match the theory and the reports I've heard.[/quote] It's all sealed up now, but I will experiment next time. [quote]Cool. Have you tried any other midrange speakers? I worked up a few theoretical designs with the 8MR but got driven mad by the peaky response - then again it saves having to build a sub cab and is far cheaper than the 6ND410. How do you find your cab stacks up against the usual 4x10" fare? Alex[/quote] The only cab I've been able to compare directly is a Trace 4x10; mine is much brighter and deeper and about a quarter the weight! Though I do appreciate that the Trace's virtue is that it although it doesn't sound particularly nice it does cut through a terrible stage sound.

Thomann are great, and the 3 year guarantee/30 day money-back-if-you-don't-like-the-colour is very reassuring. Not always the cheapest though, do check www.studiospares.com for electronics. +1 for the EC, yes! I do love travelling round Europe and seeing shut-down border posts.

[quote name='alexclaber' post='135787' date='Feb 7 2008, 02:40 PM']The cab I'm building will have ~110 litres net internal volume which combined with a 46Hz tuning frequency gives a good balance of extension and sensitivity. The Omni 15TB uses much larger internal volume and a 50Hz tuning frequency to get more loudness, not lowness, and I don't need that extra loudness. Alex[/quote] I use a Kappalite 15LF in 110 litres and it's good. I tuned it down to 36Hz though, as I use a 5 string. I also have the same driver in a 130 litre box, not much difference, if any. For mid/high I use an Alpha 8MR and bi-amp, crossed over at about 600Hz. The system is *almost* loud, deep and small, though my drummer complains that it doesn't qualify as 'small'.

[quote name='neptunehealer' post='135542' date='Feb 7 2008, 10:11 AM']Well i play in a rock/pop/soul/funk cover band and we have a few weddings booked and i need a new bass really. I am after a passive 4 string bass which isn't too heavy on the shoulders. I will spend upto £600 if i find the right one for me, thing is i know buying online is good but i do know that trying them out first is imperitive.[/quote] Why not start a new thread entitled 'Bass Wanted' - there are always basses for sale here (seems to be a bit of a sellers' market, quite often you see prices reduced when no-one bites for a few weeks) and it's a small enough community that you have less chance of getting ripped off than if you go to EvilBay.

[quote name='neepheid' post='135527' date='Feb 7 2008, 09:51 AM']I believe in praise where praise is due, so hats off to Stringbusters. I ordered a set of Super Slinky 5 at 4.30pm yesterday, standard delivery and they're here this morning. That's pretty damn good. They're too quick even for their own website, which is showing my order as "Awaiting Processing" Nice one, I'll be back.[/quote] nice prices too, and a great range

Always a good idea to ask for the serial number then Google it and see where else it appears. You can also cross-reference serial number and alleged year of manufacture; here for Fenders: [url="http://www.fender.com/support/usa_instruments.php"]http://www.fender.com/support/usa_instruments.php[/url]

[quote name='gilmour' post='135163' date='Feb 6 2008, 05:09 PM']If you are gigging that often you deserve a new bass![/quote] What he said!

[quote name='neptunehealer' post='135155' date='Feb 6 2008, 05:00 PM']Yes i don't mean to critise the Vintage brand as a whole as i know some people have them on here who like them, but i did purchase my Vintage approximately 10 years ago now for £120, so maybe the quality was worse then. Oh and it sounds even worse not plugged in, it rattles at the headstock when i play it unplugged also strings break reasonably often which make me question the quality of the bridge saddles.[/quote] It sounds well f***ed. I haven't broken a string for years, and I hit them pretty hard.

Whereabouts in England are you?

[quote name='neptunehealer' post='134891' date='Feb 6 2008, 11:13 AM']Basically i hate my tone which is not unsuprising really considering i play a cheap nasty bass which is really heavy and a bitch to play. I currently have 600 watt peavey sessionbass head and a laney speaker. I have twiddled and played around with my head and still can't find the tone i am after. To describe the tone would be a muddy bland bass sound. I am wondering if i keep my rig the same and purchase a Fender Jazz bass will this alone give me the tone i am after or will i need to seek a new head/speaker aswell?[/quote] Can't do anything about its weight, and I am definitely a fan of light basses, but it being a bitch to play might just be down to the action. As for getting rid of the muddy bland sound, maybe you need a new set of Rotosound roundwounds? What's in the speaker? If it's a 15 you might like to add a 10 for a bit more bite

[quote name='andy67' post='134459' date='Feb 5 2008, 03:56 PM']That could be a goer bremmen - how much?[/quote] Do you want to try it and pay me what you think it's worth? I'll send it to you for the price of shipping.

[quote name='andy67' post='134452' date='Feb 5 2008, 03:48 PM']some good stuff folks! however, the software upgrade reviewrs keep mentioning say it makes a huge difference to the vamp?[/quote] If you post a link I'll try it. Or you could buy mine and try it yourself. It has one broken control knob (did I mention the build quality is flimsy?)

[quote name='BOD2' post='134430' date='Feb 5 2008, 03:31 PM']Also the V-Amp needs two hands free to manipulate some of the controls.[/quote] oh yes, that drove me mad, made it virtually useless for live use! The interface is much better on the Line 6.

[quote name='David Nimrod' post='134376' date='Feb 5 2008, 02:50 PM']Yeah, I'd always wondered why it was so much less than the Line6 stuff...[/quote] I have both, and the Line 6 is worth ten times the price of the Behringer. The Behringer is very noisy, and it isn't a white noise type of noise - lots of low frequency thumps and crackles. And when it clips it takes the top of your head off; it makes sounds louder than the signal being clipped. The Line 6 clips gracefully. The build quality of the Line 6 is solid, while the Behringer is flimsy. The manual of the Line 6 is carefully and clearly written. The Behringer has many sections that leave me going 'whu??? duh?' and some functions just aren't covered. Buy the real thing, not the cheapo copy.

[quote name='Ghost Rider' post='134158' date='Feb 5 2008, 10:54 AM']Hello, this is my first post on here so greetings to you all. I am quite new to playing & not sure about a good guitar or a bad guitar. I have seen a bass on eBay & wondered if anyone could identify the year or where it was made as fender squire precision bass guitars don’t seem to have a light coloured fret board with a black body so I am presuming its an older model or that the neck & body don't match. [url="http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=230218679892&ssPageName=STRK:MEWA:IT&ih=013"]http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...A:IT&ih=013[/url] ebay Item number: 230218679892 Thanks.[/quote] Hi Ghost, Squier did make black bodies with maple fretboards, I had one in the mid 80s. I don't think the one you've found is an old one, the tuners are very different from the ones on mine (which were the same as Fenders).

[quote name='Mr Bassman' post='134038' date='Feb 5 2008, 12:56 AM'][attachment=5420:aero_2.jpg] One of these should do the trick [/quote] What is it?
