I'm running a MIM Jazz with Bart 9J1's into a Sans Amp, but i find the output is low and the drive really needs to be turned up to distort (mentioned in my last post). After doing a little i research i'm looking at two options, either a bass eq pedal (probably from Boss) or popping in a J-retro preamp (seems like an easy job). What would you guys recommend? Any major +/- on either one? Are the J-Retro and Boss Eq pedals low on excess noise? Any feedback would be helpfull, Thanks.
