But to answer your question more specifically, I have had 3 Prosebasses, a Wishbass, a defretted Conklin 7 string, an LTD defretted 6 string, a Squier Jaco copy, a Shuker Jazz, a Precision, a Westone Thunder, a G&L L2000, an Eastwood eub, a Cort B4, and a few others I can't remember.
Of those, I would recommend the Westone, the G&L, and any Prosebass you can lay your hands on.
My three keepers are the Portamento, a Marusczcyk Elwood, and a sublime Firecreek ( piezo only, no controls).
Happy hunting!
