Hi, I am aware this has probably been asked but I am new to the EUB game so I don't quite understand all of the variables that go into choosing an EUB amp. I am a long time electric bass player and have a decent amp for my jazz bass. I play through a GK with no preamp or anything, just straight in. And it sounds fine. But I know since the Ergo uses piezo pickups there are different variables. I keep seeing lots of stuff about impedance, and using several different preamps and such. I just don't know what I need to be looking for. Can anyone give me an idea of at least what to look for when researching? I'd ideally love to have something fairly small (not tiny) but small combo amp. I'd prefer to not not lug around a head and cab combo like I currently do. Thanks for the help (and possible ridicule for posting this) ahead of time!
