Hi all, trying to solve a volume (I think) problem I ran into yesterday while playing my bass. Brand new bass, new strings, 5 string plugged into pedal board + pedal pre-amp into power amp. Pretty cranked on the gain. Every time I fretted a note on the low B (low E) string from like 3rd fret on, the amp/cab sounded like it would sustain the note for about a second before it felt like it was “choked” and dropped in volume and then it sounded like it struggled to cut through, so it would come back up a little in volume and then drop back down. It wasn’t a smooth steady decay/release, it felt like a square wave in declining volume. It was pretty consistent in occurrence. Sounded like a bad fart haha! These were single notes, just struck to ring out, the fretting was accurate, the bass and pickup height is factory set. The only new items in the mix are A) the new pre-amp pedal, B) the actual bass. Everywhere else on the bass, including chords on higher notes and just an open low B sustained and released very beautifully and consistently. I will try to zero out the EQ on the pedal and see if that does anything. Any other ideas on what this may be? I tried recording on my phone but you can’t really make it out. Bass: Ibanez 305 Thank you all!
