Hello Doug, Been watching your work over years! Please keep doing it! Have learnt a lot from your techniques! I just recently bought MVP 5 (made in 1988) with 4 knobs, no mid switch. Personally, I always prefer 3 bands over 2 bands, but can't deny MVP sound. Then, I saw other thread that you installed ntmb to your MVP, instead of TBT?, and your sound is very attractive or even better than the original one. (not talking about technique coz my playing will never be close to you!) So, I did that too (mine is ntmb-918f with 4 knobs; vol, pan, mid [push,pull], tre.+bass stack), but my sound is not even close to you or real MVP sound (that I used to). I've found it terrible tre. (not as clear as piano that I had before), not useful midrange sweep, overall is worse.... My question is: did you do any other modification on ntmb or pot? ie. resistance on tre. pot / what the little black switches (3?) are for? etc.? Any suggestion is much appreciated! KS.
