Fantastic Sounding amp from 1965/66 in extremely clean condition.

Despite what the Vintage Guitar magazine guide says, it seems to have been proven that this model is not the Jimmy Page / Led Zeppelin I amp. Weird because you can absolutely cop those tones if you grab a vintage tele and crank this amp up. Either way, this amp is absolutely amazing tonewise and condition-wise. Grab a piece of history.

Also, It records ridiculously well with Guitar or Bass.

Comes with a swanky custom made cover.

* not interested in any trades. Like, really. Not even whatever thing you might have for trade. Cash only. Thanks!
