I have this homemade (not by me) electric upright with a K&K Bass Max pickup (I think). I bought a new rig for my electric playing, and didn't expect it to have much impact on the EUB sound, but actually it was really dramatically better. (much more like an acoustic upright bass) It's not louder, but it's fuller, and just feels more relaxed and easy. The sound blooms. The new set up is Aguilar 2x12 instead of Eden 2x10. Also, I got a Thunderfunk amp, which has magical powers compared to my previous GK amp. The bass sound in its entirety is boom, right there, in the whole room. I have thought about getting a minimally small rig to amplify the EUB, but after hearing it through this rig, it's worth hauling around.
