GrindCustoms TSM680
This is a GrindCustoms UltraStoner PCB built to TSM680 specs and it sounds great. Has a huge mid boost and just makes this Big Muff variant just pop out. I found with little fiddling around with it and with my Gibson SG I was able to nail many of the great stoner rock and psychedelic bands tones with ease. From Sleep to Red Fang with no problems.
Rej suggested that I put this in a multi build with the UltraStoner built to stock… I just may.
