Up for sale is a 1969 Marshall vintage style hand wired main board for the JMP100 model 1959 Super Lead.

Made from the exact same electrical grade resin board used by Marshall in '69.

Amps with this era board material tend to have a warmer unique vintage tone that is harder to replicate with modern materials. It has to do with the electrical isolation specs, humidity resistance and how these factors interact with electric fields.

The board is 12.375" x 3" x 1/8" thick.

All of the coupling capacitor outside foil leads were hand tested and marked prior to installation and have all been properly aligned according to the circuit in the board diagram for lowest noise floor.

If you'd like the Super Bass version or the JMP50 version of this board, just let me know and I can set up a custom listing for your purchase.

Thanks for looking!
