I am playing an acoustic guitar with a Seymour Duncan Woody SC Single-Coil sound hole pickup thru a Roland Cube 15 amp and not getting much output. I have to crank up the volume to max to get enough volume to be heard in a room holding maybe 200 people and no other instruments. I figure I needed a preamp. I had read on another site that you could build a preamp out of a smaller amp by "rerouting the out-to-speaker wires to the big amp's input and rerouting the small amp's input to be the big amp's input." But then someone else said this was not possible. The site also said that "virtually any electronic device that projects sound has the basis of a pre-amp." Is it as simple as it sounds or should I just go buy a preamp? Any suggestions on a good inexpensive preamp ($100 or less)?
Hmm, is a battery required for the Seymour sound hole pickup? Have you checked Seymour Duncan's website for a possible solution? Try emailing SD - they are good with responding to emails with technical questions.
At first I though maybe you needed a DI box but that is usually when you are plugging into a PA system, not a guitar amp. Does the amp have multiple inputs? If so, you want to use the Hi-Z/Instrument input.
A single-coil soundhole PU should work just fine; it's essentially an electric guitar pickup.
How is the distance from the pole pieces to the strings? That can make a big difference.
My setup is an ABC Morley ABC Box, that A goes to my electric chain and an electric amp and B goes to another electric pedal chain, and C goes directly into an acoustic amp. When I play my acoutics I will normally stereo my acoustic "C" chain and acoustic amp with the "A" electric chain and I have the DI box at the end of the chain and run it into my electric amp, or when I just use the electric amp for my acoustic.
Also, I actually use it with my telecaster's single coil pickups when I want a "clean" sound from them. It boost their signals beautifully.
I have used it into a PA and it sounds great. It should work great with the guitar going straight into the DI box and DI out straight to an electric amp. It muddies up going into an acoustic amp, but does what it's supposed to do into an electric amp.
Also, some of you have seen this vid I made, but I am using an Epi EJ-200, with a cheap Lace California soundhole pickup and running through and electric chain, with reverb, delay, and some O/D using the Behringer DI box to two high end tube heads and cabs. Excuse my playing but it gives a pretty decent sound. Some may be going for a more acoustic sound but it can be achieved with some knob tweaking.
