1978 was a great year for these old Marshall Amps. 2026 was even a better year for Monomyth to turn it into a fire breathing monster. The work inside is like artwork. The sound is unmatched to anything in its category.
All original transformers. Has KT77’s which Shea said works best with the mod. You can still use 6550’s If preferred.
I have included a screen shot showing what each switch/toggle does.
Shipping will be a flat $109.00 to the lower 48 of the USA. Fully insured and signature required.
