Hi! Seem to be having an issue with my Yamaha RBX800. For some reason, the output on it is fairly low--it can barely be heard over my drummer. I am playing through a Trace Elliot Commader 100watt amp, and it is barely present when played at high volumes (maxed out at the amp, maxed at the bass). Yet, it I use my Cort P-Bass with Quarter Pounders, at the same amp settings it makes the wall shake--I actually have to turn the bass down a good bit! Same thing with my active Squier Jaguar (though I don't know how accurate a comparison that would be...). I have recently rewired the bass since it had some weird neck volume-master volume--master tone thing going. It got a little louder. Of course, if I run both pickups at full, I do lose a noticeable amount of volume. I seem to get the most volume from just the split coil at the neck (which is as close as I can get to the strings with it). The jazz pick up is a little lower. Seems like the best compromise is neck at 100% and bridge at about 30%. New strings, too (roundwounds). As to the question: does this sound like an issue with the pick ups, or am I expecting too much out of the bass (especially when compared to the other two basses)? Thanks for your help!
