Vintage Japanese effects unit, super high-quality pro-audio equipment
After suspecting that the GX60 Ibanez guitar amp that I've recently come across was built by Maxon, the discovery of this beauty may have confirmed it. The circuit boards inside the casing all have Maxon stamped on them and it all looks super clean as well.
This will need repair, however. It powers up fine and switches between effects, but the effects don't actually kick in unless you crank the volume to the max. Something must be shorted out somewhere. Hopefully it will be an easy fix. When I'm able to find the sweet spot and this thing works like it should, the sounds are top-notch.
This has a very large following in the collector's market, like most 70s and early-80s Ibanez gear. Famous players who used this model, which was manufactured between 1977 and 1979 are Jerry Garcia and Bob Weir of the Grateful Dead and Steve Miller. On top of being highly-collectable, these are also incredibly rare. I've seen it listed from anywhere between $550 and $1200 recently.
Thanks for looking, more high-resolution photos here.
