I just bought this today off of CL for $160 as I wanted a smallish rig to leave at my friends place when we play there. Never had a Trace before but thought for $160 it would be perfect for a leave over/jam type affair. It seemed pretty solid when I played it at the sellers home. I do seem to be hearing what I feel to be a bit of excessive hum coming from the speaker now that I have it home. I did hook it to another cab and still the same constant hum. Not being familiar with Trace, is this low,constant hum one of their quirks? Still, it does have a nice tone but the hum has me concerned.
