I'm in the market for a new UB PU. I'v been playing and amplifying UBs for years. The first PU I had was a Polytone that eventually self destructed due to the design (mechanical tensioning between the feet). Anyone remember the Polytone PU? Then I got a bass with a wire PU embedded in the body of the bridge (no idea who made it). Both PUs sounded pretty good for the early seventies. Then I got an Underwood when they first came out. I think that was the start of the piezo era ('79?). Then a Barcus Berry, not bad. Then a Fishman YUCK!! The problem with most UB PUs is that they eventually go bad and after many repairs to the cable (usually where it attaches to the pu) they just stop working. I've tried mics but in close proximity to amps and any volume (i.e. club gigs) there's the feed back issue. A buddy has a realist and the sound is a fairly accurate reproduction of the actual UB's tone but the cost scares me since I've spent so much over the years. I've read some of the testamonials for the K&K Bass Max, which for the money seems to be a pretty good deal. Soo, after spending mucho dinero on PUs I want to get some bang for my buck. Using the Fishman, Barcus Berry, and Realist as a bench mark how does the Bass Max stack up? Does any body have A-B comparison opinions between the Realist, Bass Max, Fishman, or any other hot new PUs?
