Awright, I'm thinking about one of these stomp-box sized preamps, and I'd like to hear comments. I mostly play a Precision with flats, and I'd like to be able to vary my sound a bit more than I can now. There are a ton of these preamps available within about a hundred bucks of each other, but I can't go anywhere and A/B/C/D/E ... them , so I'd like to hear what users have to say. I'm looking at: Sans amp Bass Driver DI Aguilar DB 924 Sadowsky Outboard Bass Preamp/DI Raven Labs PHA-1 Fodera Model 2000 K & K and others. I can only buy one at this time. I could also probably buy a used Peavey Max, which I realize is a whole different deal, but may be worth considering. I would be interested in using these either with a head or combo or directly into a power amp. Help!
