I had Dan Gower mod this amp for me, all work was done by him this year. Original amp is a Marshall 1959 SLP built in 2015. Amp was very clean inside before the mods, no issues at all. This has the Rockmonster Mod done to it along with a bunch of other options and upgrades :
- Rockmonster Mod
- NOS Mustard Capacitors upgrade
- 3 way saturation switch
- 3 way mid shift control
- Glass control (Negative feedback)
- Thump Control
- Thump Control pull switch for bass or low mid
