God I love this bass! My MTD-535 is one of the most responsive basses I've ever played. I have a question though, about the high end (treble) response. It seems there a pretty big peak in the active preamp, right around 6-8 khz or so. It's driving some of my amps nuts. The bass is so dynamic that it tends to overload the amp from time to time, especially when I turn up the treble control. I can't turn it up more than midway, without causing problems at high volumes. My question to MTD owners is: have you encountered this issue, and if so what have you done about it? When I think about a solution, my head goes to "parametric EQ" or "notch filter". Am I on the right track? I tried a passive treble-cut, but that doesn't seem to achieve the desired result. It cuts "all" of the treble, instead of just the peak around 6-8 kHz. Any creative thoughts and clever suggestions would be greatly appreciated!
