Hey guys. I've encountered a problem with my amp and I'm wondering if any of you guys have advice or technical knowledge you'd be willing to impart.
Just to get it out of the way, I live in a small mountain town in Canada and money is an issue so sending my amp to a qualified Engl tech isn't in the cards right now and the local "Amp Tech" charges an arm and a leg and doesn't exactly inspire confidence.
On to the problem. I've encountered a strange noise on my lead channel. It's only detectable while palm muting and letting the note ring out/fade away. It's kind of a mix of buzzing and almost grinding, and seems to get louder as the noise of the guitar fades away. This is not normal amp hum. Way too loud.
It's there with or without the noise gate engaged. It's not audible on the clean channel.
I had the tubes tested and according to the local "expert" they're fine.
Here's the weird part: In the local music store I couldn't get it to make this noise. It sounded perfect. I take it home again and it's back. I've been running it through a Marshall 2x12 and borrowed an EVH 4x12 to make sure it wasn't the cabinet. I moved the head from one cab to the other and it seemed to go away, but slowly came back over the course of a jam.
I picked up a replacement pre-amp tube and was going to try and troubleshoot this thing to see if one is faulty, but not faulty enough to test negative. This being my first 'real' guitar head and me being primarily a drummer I thought before I start mucking about with things I really don't understand, I'd ask the community and see if anyone one out there would be so kind as to assist me in my ignorance.
Any advice would be great. I'm in over my head here.
