so, my man will (wilbyman) hooked me up with a bart ntbt. he didnt have the nut to mount the bass/treble stack pot though. i ended up heading over to the hardware store over confident thinking id find what i needed. wrong! so, not knowing where the hell to get this metric nut, i emailed brian asking if he knew where i could buy those type of parts. he said since its not a standard size it wasnt something that was easily found. well, he ended up just sending me the part i needed. i was stoked because i thought i was going to have a wiggly pot forever. buy stuff from bestbassgear i know i will if i need something!
