Re: Acoustic Pickup. Electric Guitar.
thing with a transducer is, it senses vibrations and converts it into an electrical signal.
In the case of an acoustic guitar, the transducer is placed on the underside of the guitar's top/soundboard, which vibrates quite a lot (in comparison to a solid bodied electric guitar). You might not even get much of a sound if you placed a transducer on a solid body.
It might work on a hollowbody electric.
But on a solid body, you have very limited options as to where to place a transducer to get the string vibrations. for a Fender style tremolo bridge, you could put it on the string block, but you'd probably end up with a really thin, tinny, bright sound.
Alternatively, if your guitar was chambered and you had HUGE chambers, it could probably work on one of the thinner walls of said chamber...if you could even access it in the first place.
other than that, though, I think you're SOL.
If you want acoustic sounds out of an electric guitar, you could get a set of piezo saddles. Graphtech makes a bunch. so do a bunch of other manufacturers. What kind of guitar do you have?
