Hi, I'm having trouble with this Lowballer build. It only works with the toggle switch in the off position. I removed and replaced it. Same issue. Also when it's off, the only pot that changes the effect seems to be the bass pot. I switched out the LM1458 and the JRC4558 and it had no change. I pulled out the ICs and reflowed the solder, still nothing. I'm fairly new to pedal building but didn't think this would be too big a challenge. Any help would be greatly appreciated.
