Folks, I wandered over here from the BG side of the board in search of some help. I have a Euphonic Audio iAmp Micro for sale in the BG Classifieds, and received the following inquiry: "Can you plug a piezo pickup directly into this or do you still need a buffer pre like a fishman etc.? I'm sick of using my pro platinum for my upright and want a small combo that can handle my bass max pickup." This is well beyond my range of expertise. Can anyone help out with an answer? Many thanks in advance!
