This amp is loaded with every available option for this model. I am the third owner of this amp. I bought it on Ebay so this info is from the 2nd owner. The amp is not for me. I'm a Fender Guy. So it goes.Recently serviced it is in perfect working order. All Pots and faders are clean and quiet. This is a serious stage amp with incredibly rich, tube saturation that delivers clean sounds with miles of headroom, smooth breakup crunch sounds, or that creamy, over-saturated distortion a al Carlos Santana. If you want that sound - THIS IS IT!!Features:

Original user manual - printed from the InternetPower Tubes are (2) matched NOS Philips 6Ls 7581a with very low hours, (2) Groove Tubes GT-6L6RThis amp is in VERY NICE SHAPE and looks GOOD, however, it is 35 years old. The tolex is ripped around a couple of the corners, wrinkled around the handle, and the metal hardware is a little rusty in a couple of places. All 4 of the EQ slider knobs are gone. This seems to be common on the M/B's. The sliders still work you just have to use your finder nail. Small scrape on the metal heat sink fins on the back. Slip Cover is torn but still works.
