Hey guys, I have a sound-related issue with my 5:50 that I hope y’all can help solve. First I’ll try and describe it. When I’m playing a lead (5W, not loud), using the crunch or burn channels (gain not cranked to max), when I get to around the 9th fret and above on the high E string (10 gage strings) the individual notes are very shrill and most unpleasant. I don’t know how else to describe the sound other than use the word shrill. I need to figure out how I can use the same, or higher, gain level and get a smoother, cleaner sound without so much nasty bite. I’ve read in other threads that new tubes (from Doug’s, for example) really improves the overall sound but I don’t’ know if this is a tube thing or just a vagary of the Black Shadow speaker. Has anyone else experienced this issue? If so, is it a characteristic of the amp? Do different tubes fix/make this better? Thank you in advance!!!
