This page is for ordering mods for the Marshall SC20C and SV20C series combos as well as certain Friedman combo amplifiers only.
For those ordering Hot Mod V2 Evo and Mr. Scary Mods for Marshall SC20C and SV20C and Friedman Runt 20, Runt 50-watt, and JJ Jr. combos, we now have a fastening system available. The fastener system enables the installation of the mod in these “upside down” applications where the mod’s L-bracket and thumbscrew assembly can’t be used due to these amps not having a tube shield base to secure the mod.
Note that other combo amps from Marshall on our compatibility list as well as Friedman combos such as the BE, Smallbox, and PT model combos do NOT require this fastening system and instead can use our standard L bracket and thumbscrew assembly.
Note that for easiest installation and access, the instructions ask for removal of the chassis from its enclosure. If you are uncomfortable doing that, you’ll want to take your amp to a technician for installation.
