decided after 15 years to mod my bass with pickups and a new preamp. a friend recommended east preamps so we installed a uni-pre and a set of bartolini m4's. pretty stoked with how it turned out, though i'm still on the learning curve for dialing it in (too many knobs for my old brain). mucked around a bit and came up with this short clip to test it in a mix.
Awesome. The USA Barts are just some of the best things you can get
I have a couple of the G6s through a Bart 5.2 Preamp in my fretted TRB, love them.
