Gallien-Krueger MB500 Fusion bass head in excellent condition. Used lightly as a backup to my rack rig. This one's kind of interesting. When I bought it (I'm the second owner) the mute switch didn't work, so I took it in for service. The tech somehow screwed up soldering in the new switch and G-K replaced a good deal of the guts of the amp (see photo). Apparently to replace the front board with the controls, that board comes as part of a larger board replacement set. So...a lot of the amp is basically new (importantly including the knobs, switches, and jacks which can be trouble spots over the years). It works like a charm—including the mute switch! I've decided to just carry my tiny MB200 as a backup, so I'm selling its big brother to someone who might enjoy its tubey-ish goodness. I'll include the rack ears for mounting, a $40 value if bought from GK. Price doesn't include actual shipping cost which I'll split with the purchaser. Canada Post costs to US aren't much different than USPS costs. PayPal or preferred Interact Direct transfer within Canada. ------------------------------------------------------- SPECS: The Gallien-Krueger MB Fusion 500 incorporates the same all-tube preamp of the Fusion 550 and maintains the amazing portability of the MB2-500.
