[quote name='tks.se' timestamp='1412160565' post='2566219'] When playing a low B, most of the tone consists of harmonics to the fundamental. Here's the result of playing a low B and running the signal through a spectrum analyser: [/quote] That's an interesting result, and one which I'm rather surprised by. I was expecting a succession of even harmonics and not much in the way of odd, but the odd harmonics are there in force. The reason I'm surprised is that with even harmonics there's a node at the 12th fret, while with odd harmonics there's an antinode there. Mind you, the fundamental also has an antinode there, so perhaps I shouldn't be so surprised.

I use a clip-on fan, about 6" diameter, which will just about clip onto a speaker stand or sit on top of my cab. Not as powerful as a big floor fan but takes the edge off the heat.

[quote name='HowieBass' timestamp='1412206307' post='2566841'] Yeah I think I first learned about Fourier Series when I did A Level physics though I've never used that knowledge in any practical setting - what was your signal generator for? [/quote] Just testing audio pathways. It was a signal injector, I remember now - a 7400 IC, the odd capacitor and resistor, all on a bit of veroboard in a 35mm film container with a length of threaded rod sticking out of it. This was 40 years ago so it's a bit of a struggle remembering, especially these days when breakfast is a bit of a mystery. I also wrote a program for a Sinclair QL which built up a display of a square wave from the harmonics.

[quote name='HowieBass' timestamp='1410389229' post='2549045'] I think he means 'harmonics that are lower in volume than that of the fundamental frequency of the square wave'. [/quote] A square wave is actually made up of a series of sine waves, all the odd harmonics of the signal. The amplitude of each harmonic is inversely proportional to its harmonic relationship, so if the fundamental is 1V p-p, the 3rd harmonic will be 1/3V p-p, the 5th harmonic will be 1/5V p-p, the 7th harmonic 1/7V p-p, and so [i]ad infinitum[/i]. I once built a square wave generator using a TTL IC, so it was providing 5V p-p, tuned to about 1kHz, and it would happily radiate into the RF range.

I thought it was 2x250 into 4 ohms, 2x175 into 8 ohms. And, indeed, doing a quick google, Ashdown's website agrees with me (and it was them that told me it was 2x175 into 8 ohms). There is a Superduperfly, the 1000W version, which has an internal fan and runs nice and cool.

[quote name='bassmachine2112' timestamp='1411745739' post='2562510'] Made in USA/handcrafted basses are good. Foundation basses are very good. [/quote] BXP basses are very good. Although there's not a lot in it, I actually prefer the BXP Grind 5-string neck to both the BXP and USA Cirrus necks (played all three back to back so I could make a direct comparison).

[quote name='alyctes' timestamp='1411423737' post='2559475'] The battery is under the neckplate? Surely then you'd have to remove the strings to change the battery?! [/quote] I doubt it. The screws holding the neckplate on are diddy scratchplate-type screws, so presumably it's a cover plate concealing both the battery and the actual neck screws. Either that or the neck pocket is tight beyond Fender's wildest dreams.

[quote name='dudewheresmybass' timestamp='1411030894' post='2555664'] Is it just me or are there two different girls pictured? One in the woods, and a differing one in the bedroom? [/quote] The one in the bedroom is the one he's just strangled and hasn't yet disposed of the body.

Just program change and apparently you can put it into tuner mode too, though I haven't found out how to yet. If you've got a Windows PC, download and install MIDI-OX, connect the MS60B, start up MIDI-OX, go to Options | MIDI devices and select the MS60B in MIDI Outputs and click OK, then move your mouse along the toolbar until you find "Send MIDI controller messages", click on that, and you'll see a window that you can either select an absolute patch number from (upper right hand section, patch number = ((section - 1) * 8) + number) or scroll through patches (in the bottom part of the window, select "Patch change" from the drop-down on the left and then scroll up and down with "Value" on the right). I'm going to see if I can do some sniffing to find what other signals the Edit & Share software sends to a B3 and see if the MS60B reacts to any of those.

Must have a shot at MIDI control of a B3. I've got MIDI control of an MS-60B, though I'll need to build something to do the job as lugging around a desktop just to change patches is a non-ideal solution.

[quote name='Bassassin' timestamp='1410304993' post='2548119'] I reckon it's a Hohner B2A modified with body wings & a veneer on the front covering the original pickup routes. I quite like it. [/quote] Control cavity is wrong for a B2A but it could well be a B2 - the control cavity is at a slant to the neck-through, which is right for being parallel to the bottom edge of a B2 body. Looks a very neat job. If it had one more string, I'd be tempted.

How about something a little different: [url="http://www.ebay.co.uk/itm/Carved-alder-Guitar-Body-for-Precision-Bass-/261584344766"]http://www.ebay.co.uk/itm/Carved-alder-Guitar-Body-for-Precision-Bass-/261584344766[/url]

[quote name='Annoying Twit' timestamp='1409872457' post='2544294'] Ah, gotcha. I didn't realise it was the toy Thumb. I interpreted it as a full size one. Which made my eyes pop out at the size of the speaker on that amp! [/quote] Ah yes, the 24" woofer. And don't forget the big knobs on the amp. Everyone should have big knobs.

I think that in any band, members have got to be able to give and receive constructive criticism. However, if it's happening constantly rather than occasionally, then there is something wrong with either the criticiser or the criticisee.

[quote name='Annoying Twit' timestamp='1409840206' post='2543837'] @tauzero - in that photo, your speaker looks to be even bigger than 15". It makes the bass look short scale. How big is it? [/quote] The Thumb is 17" scale (and not suitable for conversion to Ashboryness). And although the GK was a bit more than £31, the Thumb certainly wasn't.

ZZ Top's song. She Sells Thanctuary, mathter. There is one song which isn't root notes all the way through, but is one note all the way through - Waterfront by Simple Minds.

[quote name='ubit' timestamp='1409492980' post='2540134'] I'm gonna definitely stick with this one, but what the hell can I buy her now to match this ;( [/quote] So far I've bought Mrs Zero two ocarinas, a stylophone, and (for one Valentine's Day) a didgeridoo. There's plenty of instruments out there...

Seeing as we've moved from providing info to willy waving, I took a GK combo, Westone Quantum, bag containing leads and Boss ME6B, and a sleeping bag on the back of a Triumph Tiger 900 from Tamworth to Maidstone and back again.
