I found this little preamp on the maplin website, and I was wondering if I could use it as a little signal boost in my guitar (like an EMG afterburner). Would this work, or would it amplify the signal from the pickups too much?

Thanks

Don't know how it would sound but could be alright. The problem with it is it could be noisy and you'd have no way of telling before. But then again, it is gonna be pretty much the same components as a "booteek" boost so meybe it will be good. Sorry - guess I haven't been much help.

I don't think it would be too difficult to make one from scratch though!

its pretty easy to make a booster from scratch and mount it in your guitar if you've got enough space in your cavity...

though that little thing is only only 7 quid....but it seems to be designed for microphones, not guitars, and if its amplifiys 80x thats way too much for guitar use

edit: boosters

if you're mounting it in the guitar you could use trimpots for a preset level of boost and wire a push-pull pot to turn it on/off... though plenty of different implementations are possible (constantly boosting it before the volume control of the guitar for example...)

also put a stereo jack and wire it so it'll turn off when you take the plug out

Thanks, I'll check out those links. You guys just saved me £5

EDIT

It says this: Amplification: approx. 65 x at UB 9V, approx. 80 x at UB 12V, approx. 100 x at UB 24V

From this it looks like the amplification gets greater with voltage. Do you think I could just run a smaller voltage to cut the amplification? Or will it just stop working below a certain voltage?

It's not going to amplify any more than two watts at best. This "65 x" stuff sounds like rubbish. Why can't it say in watts or dB!
