| Acoustic Guitar Preamp
I currently use a Jim Deacan electro-acoustic which has a "Shadow P7" preamp. At my last couple of gigs with a PA, the sound has been poor quality, with a boomy presence and crackles here and there. Last night when playing I decided to lower the sub-bass range which caused the guitar to fail to give out any sound. I managed to get it to give out some again by moving the sub bass slider around, but still the sound was very "tinny".
My question is, are ACoustic Pre-amps a standard size so I can take ou the ShadowP7 and replace it with a new one in the same hole. How much will one cost? Or, is it possible to repair a pre-amp? From what I can see it's a closed unit with just the one digital circuit board inside.
