Marshall JCM 900 Hi-Gain Dual Reverb 100 watt head Model 4100
This amp is used. It functions perfectly, cosmetically it has it's share of bumps and bruises in the tolex. The rubber/metal handle on the amp is getting old/stretched but it is mounted properly and functions properly. The back metal plate cover that came with the amp new is missing. The power amp tubes in it right now are JJ KT 77's. The transformers are labeled with Dagnall part #'s. This amp was gigged with on and off for years but it was not abused. The head shell has no cracks or repairs it's tolex is just a little bruised. The amp comes with it's power cord. The bottom of the amp has the original feet attached to the amp. I don't think anyone has ever removed the feet since new. Sounds great, is relatively quiet for a Marshall JCM and definitely delivers the period correct marshall sound. Say what you will about the 900s, this is a nice amp and a good platform for mods if you are so inclined. Pairing down my head collection. Time for this to move along to its next home!
