A vintage Ampeg M-15 "Big M" 1x15 tube combo amp. It has been recently service and includes original speaker and transformers. The M-15 features a great clean tone that turns into a thick, tweed-ish overdrive as you turn up the volume. The 15-inch speaker has a nice, round bottom end, making it great for jazz or blues lead work. This amp has been cleaned and tested. It is fully functional and sounds great.
