I have the graphtech acoustiphonic piezo system installed in my guitar. I have the preamp ran to a mixer. The mixer is connected to a 300w amp and the amp is connected to a set 90w rms pa speaker. The piezo system sounds absolutley amazing, but the output level is not strong at all. I have the potentiometer on the preamp turned all the way up and the amp turned all the way up. Is there some other preamp that I can put between the piezo premp and the mixer that would boost the signal without sacrificing tone. Hopefully within a nice price range.
Thanks for the reply. That looks like what I need, but It's a little bit out of my price range and other alternatives?
Well, what is your price range?

Not that I know of.
I'm putting my GAS on hold
for a couple months in order to pimp my ride.

Don't judge me.
