Just got a NTMB preamp and installed it in my bass last night, but it started cutting in and out. I traced it down to the wires going into the little gain trim pot that is glued to the side of the main module. Has anyone ever had an issue with that before? I'm going to see if a little local parts store will have a 5k trim pot and just replace it and not glue this one down. Toyed with the idea of just hard wiring it where it would run the equivalent of half open, but I'd rather have the actual adjustment so I can use it in conjunction with pickup height to fine tone the tone where I want it.
