1977 Marshall Super Lead 100w MK II Tube Guitar Amp Head Modded #46467

Availability: In stock



WORKING CONDITION: Very Good - This amp is in very good working condition. We don't know who did the modifications on this amp but they are extensive, but with that, it seems to be working as intended. What was formerly a pretty basic Marshall is now quite a versatile amp. We can't say we can explain all the mods in detail but it is fun to experiment with and the gain achieved is quite good. Having a tremolo on this era Marshall is cool too. The new owner will have fun discovering what this thing can do. 

 Good - As seen the amp has a plethora of modifications that add to the activity of options on the front and back panels. Fortunately, everything has been labeled so you have a chance at deciphering what is going on. The tolex chassis of the amp has a few minor tears around it. The vent on top of the head is slightly warped and chipped. Some metal parts are oxidized as well. However, everything is solidly built, intact, and in good physical condition.
