Stumbled upon these two modders and watched a few youtube videoes.
What intrigues me the most is that they mod 5150s/6550s and from what I have seen in the videos it sounds pretty good.
Has anyone tried it in person?
Love it to death but something else came up that I've been wanting since I started playing guitar back in the 80s. :D
Anyway, everything you need to know about it is in this thread: http://www.metalguitarist.org/forum/guitar-gear-discussion/23965-nad-say-hello-my-little-blue-friend.html
Now I can see why some people really search for FJA modded amp heads/preamps and whatnot. I've been kind of drooling over the this tone :
Call me crazy, but put your guitar to Eb and do a little bit of tweaking and you could get a solid, punchy rhythm tone (maybe even old school Schaffer?)
