Considered the "Marshall Killer" in its day, this is a virtually mint 1978 130 watt (4 6L6 power tubes) Artist Combo amp. Complete with 4 button channel selector and channel combiner and reverb foot switch with cover. Has unique "Automix" circuit so you can integrate channels with clean and dirt mix at the exact same time. Has a beefy new 15" Eminence Legend speaker. Great amp for steel guitar as well. This amp rocks like none I've ever owned. Hate to do it however I'm 60 years of ages and require to sell this amp and other things.
