Modification of a Pignose 7-100

Description: This mod was to include an 8ohm out for a speaker cabinet or equal impedance. It also includes the internal speaker cut so it does not play when connected to a speaker cab.

Thank you to Tanner Matchus of Montpelier, Vermont for modifying my 1974 Pignose 7-100. Sounds quality of the amplifier after the mods were unaffected.

In January of 2021, the speaker was replaced with a stock speaker from a newer version of the same amp.
