/\/\ then why does it sound amazing lol
That sounds like a switching circuit problem and not a tube problem. As suggested above, unplugging footswitch is a good start.metalstorm":yl5wju1f said:Seems like folks here know a bit about Lee Jacksons and high gain amps in general, so I'm wondering if anyone can help me diagnose a problem. I've got an LJ XLS1000 and I love it. Great amp. But it has an intermittent problem. I'll be playing in the gain channel, thrashing away and the gain just fades out. The gain channel indicator light fades out and the clean channel light comes one, it's as if the amp is back in clean channel. If I wait awhile the gain channel will return. It's intermittent, sometimes I can play for an hour and it won't happen, sometimes it happens 5 minutes after I start. Is this typical of a tube failing? I have a thermal camera and I took a picture of the preamp tubes and the 4th one in does seem to be running a little hotter (and the 2nd one in slightly cooler).
Related question: what makes/models of preamp tubes do you recommend in this head? I like late 80's metal tones up to current metal sounds.
