I've come to the conclusion that I'm just not crazy about the 2 band Bart preamp (NTBT) on my Ibanez GWB1 (fretless 5 string). I like 3 band. I like being able to boost mids. Currently I'm boosting mids on my amp. Do-able, but I like having the sound I want dial-able from the bass. So - Bart NTMB or Aguilar OPB3? Or other? Or don't mod the bass at all (a 3 band pre will require drilling an additional hole). Your thoughts, brothers and sisters of the low end?
