I've been playing the guitar for almost five years now, but I'm having a problem that makes it very hard for me to improve my playing and to enjoy it.
I'm playing an Epiphone Dot and a Yamaha Pacifica 112 through a Marshall MG30 (and before on a now broken MG15 where I had the same problem).
Whenever I play an electric guitar at home through an amplifier, playing notes on the high B and E strings is very uncomfortable for my ears. It's hard to explain exactly but it feels like pressure and as if my eardrums are going to explode the louder I play the note. This happens even at low volumes (master volume set at around 1/10), and on both clean and distorted channels.
I'm sitting up to about 5 meters away from the amp.
I have this problem on all pickup positions and the only ways to make it go away are to either reduce the tone with the guitar knob by a lot or by almost completely decreasing highs and mids on the amplifier, or I can reduce volume even more, but then the sound is obviously a problem.
Because of this I've more or less abandoned playing electric guitars and only played an acoustic guitar for a long time. For the past year, I've been playing a lot of Rocksmith and it reminded me of how much I actually love to play the electric guitar, and it would sound so much better through a real amplifier.
I've had a guitar tutor a few years ago and when I had lessons with a similar Marshall amplifier in an school class room, I didn't have this problem even though I was sitting right next to it. When I told the tutor, he didn't know either what I could do.
So then I thought it might have to do with the room, but I have tried playing in three different rooms in my flat and the problem remains the same. They are all filled with furniture.
I've been searching for a solution to this problem for a long time, but I find almost nothing about it. I'd love to learn some solos, but can't really progress my playing without getting a decent sound, so I'd appreciate any ideas and suggestions what I could try.
