Hi, I've just purchased a Yamaha RBX 374 second hand on ebay & am having some issues I hope someone might know something about. The bass pot (ie low freq. pot) makes the E & A strings seem unnaturally loud to the point of being overdriven, creating distortion at even low volume, while the D & G seem too quiet. If I play very softly on the E & A they don't distort, but when I dig in it's a muddy buzzy mess. The distortion starts just before 1/2 bass pot , getting worse until its a muddy mess at full bass pot (by which time the D & G sound Oprah - i.e. lovely & warm & fat!). The battery for the active pickups is brand new. Cant tell you what guage the strings are but they look thick - E could easily be used as a B. Ive played a few 374's & 375's and have not noticed this before, so Im thinking its a set up issue. The only thing I can think of is slanting the pickups so the E side is lower than the G side. Aside from this, anyone got any suggestions? I really hope someone knows something about this kind of issue, its really bugging me that I can't play it as God intended EDIT: I've adjusted the pickup heights and this improved the D & G volume issue no end, however the E & A still distort like mad (no, not string buzz - electronic distortion). Worse on the neck pickup, the more bass pot the worse it gets. On bridge pickup with bass & treble pots wound right back to zero, it nearly disappears altogether (but this is not a setting anyone would ever use). If I use my little Korg Pandora unit to add an effect or amp style, it really gets bad. Thanks in advance!
