Re: [looper's] RE: Tube amp HUMMMMMMM...Ground?
I will try that for sure, couldn't hurt. I've always wondered how long
will a 12ax7 preamp tube last? I've got a Digitech 2112 (that's been
upgraded to the 2120) that's got the original tube it came with. It's
got to be almost 10 years old at this point. I don't use it as much as
I should, but when I do it seems to work fine and it sounds good to me.
Thanks again for the info,
Mark Sottilaro
