Sold Another Price Drop 3/8-1970 Marshall Superlead-Modded

[MetalHeadMike]

1970 1959T Super Trem 100W Superlead with B.A.T. "Bay Area Thrash mod" by FourT6and2 (Mike). This is essentially Mike's version of a Todd Langner mod from the 1980s. Five gain stages, similar to the DCP-1 preamp and Langner's other Marshall mods. Sick one of a kind amp that covers a lot of ground-not just a firebreather-killer classic Marshall tones as well, but I'm selling almost all gear to focus on other life priorities.

In addition to the mod itself, this amp was completely gone through July 15, 2025 by Mike and maintenance performed where needed, fine tuned, and tested. and ready for many years of rock and roll. Below is the list of things that were done.

Bay Area Thrash/Langner mod
Filter cap replacement-All F&T
Added Depth
Added Slope switch-Shifts mid frequencies
Added Variable NFB
Added FX Loop

The amp has original output transformer, highly sought after Dagnall C1998, but the power tranny is a Mercury Magnetics (see pics for model). Will ship with power cord, JJ EL34 power tubes and (2) EH 12ax7, (1) JJ 12ax7, and a Sovtek LPS. The power on indicator lamp unfortunately has a mind of its own and is on/off intermittently. Depth and NFB pots are new, rest of the pots are original. Headshell and tolex has dings and tears but overall good shape for its age.

sold Shipped and insured PP FF or Zelle.

Sorry, not interested in any trades at all.

That is a beautiful gut shot. All turret with original iron. I bet it sounds phenomenal

Its an incredible amp and not anything like any other Marshall mod I've owned. Its basically the 1970 stock amp on steroids.

It retains 95% of its vintage core just a tad more modern and with a much juicier feel, more low end, great clarity and with a lot more gain available if dialed up and still super natural/organic and open/raw sounding like a vintage amp instead of the over gained, filtered, neutered and sometimes sterile sound a lot of modded Marhsalls wind up with. Its still got all the mustards and other vintage components, plus the modern mod components. Zero need to boost this amp for metal of almost any kind, just plug straight in, or dial the gain back into hard rock, hair metal and classic rock goodness.
