I have 4-5 guitars. They all sound excellent for most profiles. There are always some that don't sound that great, but it is a very few that sound bad.
EXCEPT: I have this one guitar that 99% of profiles sound horrible. It's an ESP sunburst tiger. So its a higher end guitar, and its heavy as hell. The pickup is a Seymour Duncan. Screamin Demon I believe. What options do I have to try and improve the tone? Most profiles sound muffled and muddy. I don't want to change settings if it affects my other profiles for my other guitars. Other that changing the pickup, what can I do?
