Part of Magnatone’s limited-run Billy Gibbons Master Collection, this Super Fifty-Nine M-80 is a striking take on one of the company’s most powerful amplifiers. With its gold and cream finish, gold hardware, illuminated logo, and commemorative Billy Gibbons plaque, it has a presence that’s difficult to mistake for anything else.

The M-80 combines the MKI and MKII gain structures in a single, footswitchable amplifier, moving from expansive British-inspired cleans and rich edge-of-breakup tones into thick, saturated overdrive. Powered by four EL34 tubes, its 45-watt design delivers substantial headroom, low-end authority, and the dynamic response that makes these amplifiers so rewarding to play. This combo also features a 16-ohm Warehouse ET90 speaker, offering a full low end and smooth, rounded highs.

What makes this example especially appealing is the combination of limited-edition character and genuine versatility. It's a distinctive, hand-built American tube amplifier with the looks to stand out in a collection and the performance to be enjoyed regularly.

Condition

Excellent to mint condition. Upon close inspection, I have not found any blemishes worth noting. The covering, hardware, grille cloth, and illuminated logo all present exceptionally well. Please review the photographs carefully as part of the condition description.
