I think my Runt 50 is bone stock, not sure. But it screams. I love it so much, I will never change a thing on it other than required maintenance. And then I will install newest versions of whatever needs replacing.
Greg at Jalen has built lots of versions of the EVH Frankenstein for me, all with four conductor wire, so I can wire for coil splitting or parallel. I have some double creams in a LP, a clear bobbin version, some zebras, even one that looks like a Bill Lawrence for my Alex Lifeson Hentor...
I run mine with the volume dimed through a Hot Plate with its volume turned back one notch. I only play it when Mrs. Lee isn't home and I wear earplugs.
My Runt 50 slays and will probably make me thin the herd a bit in the near future. I A/B'ed it with my Suhr SL67 the other day and the Runt won. Will do that with the SLO-30 later today. I can't part with some of my big box Marshalls, but I only need one small box head and I'm loving the Runt.
Little Fighter has to be one of the toughest solos of that era. I've gotten it right before, but it was a long time ago when I had a lot more time to practice.
I also built one of these, but put it in a purple headshell. I have Merren iron. That amp gets compliments every time I have taken it out of the house - soundmen, other guitarists, bartenders, etc. It really has a special tone that cuts like a knife.
I could not bear the $26 shipping charge from CA to AZ for a single pickup from them. I mean a USPS small flat rate box is less than half that price. They told me they couldn't do anything about that, but that I could order through Sweetwater and get their free shipping. So that's what I did.
I think any builder will do a double cream for you. You just have to ask for "aged white" or some BS euphemism and they'll also send it with a plastic cover on it. I've had at least three builders make them for me and one of them was a very big name already mentioned here.
They had a brick and mortar store in Cologne, Germany back in the 80s. I went there when I was an exchange student and got to play one of those Guild Brian May guitars. IIRC, they also some of the EBMM EVHs when I was there in the early 90s too.
I started getting letters from UPS recently that say I owe them money for a package I shipped in Jan, 2022 that had too little postage on it. I think it was probably an amp I sold on Reverb, but can't find anything that matches up with the dollar amounts or dates. They say I owe them $123...
