I have an Ibanez sr 505 with the mid scoop switch and an Sr 500 without the switch that I picked up later. I noticed the sr 500 bass eq is allot weaker than the 505 with the switch. Are the active electronics that much different on these two basses? I kind of feel like there's something wrong with the 500. The pot seems to work okay. Just not as much boost as the 505 with the toggle. I have to adjust at my amp when I switch basses and it's annoying because I didn't want to have to do that. That's why I bought both is the same basses.
