B&C drivers are excellent - although last time I looked they didn't have an off-the-shelf neo 12" that was suitable for bass guitar.

[quote name='Phil-osopher10' post='1119991' date='Feb 8 2011, 12:45 PM']So looking at cabs and the different configurations that you can get, it got me thinking what are the difference in the sizes of the speakers? Do they produce different wave lengths and thus produce different sounds? I just don't get it.[/quote] Smaller speakers like 10s are better at reproducing higher frequencies than larger speakers like 15s. This has nothing to do with dispersion. Because there are plenty of exceptions in the real world, this is not a hard and fast rule but rather, as Lawrence has pointed out, a general trend. Indeed, the bigger the difference in driver size, the more apparent this characteristic becomes. As Alex says, there are more factors at work in determining 'tone' than speaker size, but the impression most people have that smaller drivers are 'faster' and 'cleaner' has a factual basis. As always, trust your ears.

Forget about using a 10 - it will struggle to go loud enough on its own. A good 12 should do the job. If you'd like to roll your own, your lowest cost option for neo is the Celestion BN12-300X, a 300W driver. Google for suppliers - there are quite a few in the UK. It works OK in a 35 litre cab, although it sounds better (goes lower) in 50 litres. The former made out of poplar ply will get you under your 10kg target weight. Don't know about 50 litres, but that might also come in at under 10kg - you'll need to do the maths. Alternatively, you could build a 35-litre cab out of 15mm birch ply which would probably work out at around 12kg. I wouldn't personally go lower than 15mm ply. If you really want 500W power handling, look at an Eminence Kappalite 12LF (a bit deficient in the upper frequencies though), or even better, a driver from 18Sound or BMS. But be prepared to pay for the privilege - worth it, but probably not for a first build.

Unfortunately, most of them are not very honest here. Efficiency is closely related to cabinet size, at least below 200Hz where it counts. A good big 'un and all that .....

[quote name='JTUK' post='1112035' date='Feb 2 2011, 09:24 AM']It is the positioning of the pups that contribute so much..esp P-bass, IMO.[/quote] I'm not convinced by this argument (which seems to be commonly held). I think the position of the pickup mainly affects the amount of low end it generates. The design of the pickup itself seems to have a much greater influence on its character. The difference between the P and Jazz is probably down to the geometry of the coil, for example. If you don't believe me, listen to a Strat. Three pickups in quite different positions, each one sounding just like a Strat.

Does anyone have a transcription of the bass line on Elkie Brook's version of 'Fool if you think it's over'? A midi file would be even better. I've been playing the Chris Rea version from a midi file, but the bass on the Elkie Brook's recording is tastier (Joe Hubbard, maybe?). Notes not tab, please.

You could try moving your cabinet to a different part of the room (not as daft as it sounds, I can assure you).

I believe (simply from reading on here) that, when they go wrong, they are not easy to repair, i.e. the usual fix is to swap out the main board, which can be expensive. No doubt someone with hands-on experience will confirm or deny this in due course.

Why does this company think that musicians who have been happy with one basic sound for 50 years (OK, two at a stretch) are now suddenly going to want 15 million sounds? Even guitarists have been happy with a Strat and a Les Paul, maybe a Tele at a push, for decades. This is a product looking for a market that isn't there. The Gamechanger thing is just embarrassing. IMO, of course.

Adrian bought a Jazz Bass pickup from me. It was a very easy and straightforward sale and Adrian was a pleasure to do business with.

[quote name='pietruszka' post='1095495' date='Jan 19 2011, 06:58 PM']My MM is 14.5 inches from centre of the pick up to the 12th fret along the centre line.[/quote] That's 368 millimetres - nearly an inch more than what Pete measures.

Bought a pair of speakers from Richard, who very kindly sent them off first-class post. Very easy chap to deal with and comes through with what he promises. Thanks.

Bought a pickup from Rich, which was well packed, despatched promptly and exactly as described. Buy with confidence!

Bought a keyboard from me. No hassles. Easy transaction. Recommended.

Just noticed that Luke has a feedback thread. Sold him a Precision a couple of years ago for a not inconsiderable amount of money. Payment was prompt and Luke was a pleasure to deal with. Better late than never :-) Stevie

I swapped the fan in my Trace AH-300 because it was noisy. It was relatively easy to do. The fan connecting wires were held in by two small screw clamps attached to a circuit board. The only awkward part was having to move the power amp board because it was stopping me from getting my screwdriver into the the clamps when I came to replace the wires. When buying a new fan, choose one that has a similar consumption to the one you are replacing. In other words, if the original one is 0.1W, that's what you should be looking for. The best place to buy them is a specialist computer store. I recently bought a Panaflo for about £3.50 from Scan computers. The good ones aren't very expensive - so go for a respected brand. It really is pointless soldiering on with a duff fan when they are so cheap and easy to swap. There are plenty of tales on the web of duff Trace Elliot fans causing the output transistors to blow up. Depending on the output trannies, the repair can be well over £100.

Not only that, but 3.9 ohms is a preferred value and therefore much easier to obtain than 4 ohms.
