I tried looking in the dedicated Sterling threads for an answer to this question, but couldn't find an answer. Since there's a whole lot of bass knowledge in this group, I'm confident somebody here can he'p. So here's the issue: I have a Sterling SUB Ray 4 that I use in the current cover band. I like the active electronics, save one issue: the pots are bottom of the line, specifically the treble and bass controls. Their center detents are almost non-existent. I want to replace them, keeping the preamp, which will mean singer/guitarist Jay will have some soldering to do (he doesn't know that yet, but I'll burn one bridge at a time on this project). Is there anything particular I need to know in purchasing new pots, or can the active circuit boards be added to any pot? I don't even know how to play them, much less work on them. LOL!
