Today I pulled out an old yamaha fretless P bass. I hadn't played this thing for a while and never through my 3 pro. It was playing fine, untill I searched for some growl and dug in a bit. from not hitting the clip light once the light when on, and stayed on and I got really nasty distortion. So I put on the -15dB and found a safe level, but in doing so got that distortion a few times (This bass is much hotter than my esp with active electronics, I found out). I was watching jaco so i got my zoom pedal and put it on the jaco setting, but in the proccess went through some nasty effects that had a REALLY hot signal and i got distortion again. I kept playing (with the input gain at about 9o'clock and active button on) nothing sounded broken, But I'm not sure. Is my amp ok?
