Yes, that was what I was commenting on. You are comparing what are very different basses, different preamps, different pickups (well, different pickups anyway, lets assume agular can make a preamp!). YOu would expect different.
I am comparing things that should be almost identical, yet they don't even sound similar. In fact, my Maruszczyk sounds more similar to the 1605 than the 2605 does. Its a puzzle!
