Re: silver jubilee
They have enough gain to have nice heavy palm muted chunk, and singing leads. The diode clipping circuit just sounds like a good OD in front of a JCM800. I've heard ones that sound great and ones that don't, but it's solely dependent on the quality of tubes you use. I have a 2550 fullsize 50W fullstack, which Jeff H heard. It's an amazing sounding Marshall that I mostly keep as a fun investment. Mine has JJ E-34L's and Sovtek 12AX7LPS, and it sounds better than it would have new in 87. The Silvers are really skyrocketing in value, so I'm hanging onto mine, but you can still find them used. They also made black Jubilees in 88/89, and the black Slash 2555 in 96.
