A couple of months ago I bought this Eden TN226 from an online auction site, with a description that read something like "The amp turns on and works at low volume, but distorts intermittently at high volume when the clip LED flashes," but I was unable to reproduce the problem.
Although I wasn't originally planning on keeping it, the various features of this specific head made it my most important practice tool and I've been using it daily, until last night when I turned it on it produced a very loud "pop" and both lights (EQ Clip and Master Clip) were permanently on.
The gain and volume are always at zero when I turn on any amp (and mute is on if there is one). It will be weeks before I get a chance to pick up a screwdriver and a multimeter, so if anyone has had a similar experience and has some insight into the problem, I'd love to hear all about it.
Thanks.
