I recently acquired an Acoustic Image Contra II with Ext Cab here on talkbass (thanks Chris!), and absolutely love it. The problem I'm having seems to be coming from my pickup. I'm currently playing through a Revolution Solo I sans pre-amp, and want to add another pickup and preamp, but I'm not exactly sure which setup would give me the most flexibility. The bottom end from my Rev is great, gets a good growl, but the upper range is just too tinny for my taste, and I want a more full sound. If anyone could point me in the right direction as far as preamps and two pickups are concerned, I'd be one happy camper.
