Wondering if anyone has run into this. I’ve had my HD-150 for decades. It’s worked fine until a few months ago, wasn’t even playing it at the time. Anyway the first channel still works spectacularly, but the bright channel with the reverb/trem(phasor) thing isn’t passing any sound. Well, the reverb tank still makes a ruckus if you give it a smack, but nothing passes from the inputs. I mostly used this channel, so it’s a bit of a bummer. Anyone seen this?
