    Hey y'all,
    Recently got this in a trade. It funtions, basically, but has some issues.
    Obnoxious open ground type hum, only works in active mode, mute switch does nothing.
    Full of tubey goodness for both bass and guitar, but can't find out much about these.
    Does anyone know common problems or component failures on these. Is pretty simple, and all physical connections seem to be sound.
    I have changed out filter caps,
    and done simple troubleshooting before. I have a good meter.
    Can anyone help ?
    Hope this is the right forum
