Marshall JMP Superbass Plexi + Flight Case ´76


Recently serviced with new JJ Tubes. It had Superlead circuit mod with new parts and came back to Superbass circuit with original parts in June of 2023. (Superlead mod parts are included too) Sounds awesome! This amp is a very good platform for pedals doing achieved sound will be realist and impressive. If you use pedals or not, it can sound rude, very interesting for stoner, doom…if you combine with a Les Paul or similar guitar for its dark and powerful character but it´s so good for blues, funk, rock…too if you combine with a Stratocaster or similar guitar. It seems not but is very versatil if you know use it.


– Power: 100 tube watts
– One channel with two inputs
– 4 New Power tubes (2023/06): 4 x E34L JJ
– 3 Preamp tubes: 3 x 5751 USA (Those ones are very clean. If you prefer other tubes with a character more interesting for overdrive I could change them without cost)

– Custom flight case

– Parts remove included (They are to modify to Superlead). Changed power tubes included.

Condition: in very good condition. Only it has a few small marks of use and age. It has only a little low noise when amp is used more than 30 minutes or so. Tech told me that this would be change resistences from power amp tubes (some of them) because usually they did this kind of problems. We decided don´t change them because originality questions. Pictures tell you about this and are part of description too.
