This is the amp you didn't know you needed.  These were made in the 60s and 70s to compete with Fender Bassman amps, and they've got a cult following among guitar players all over.  I got this amp on a random trade, and it's been one of my favorites ever since.  They're increasingly rare, but they're an affordable alternative to buying a 60s Bassman...

I have made a couple modifications to the amp to make it more user friendly.  First, I had a master volume installed to make it playable at something other than stadium volumes.  Second, I had the old, ungrounded power chord replaced with grounding to prevent accidental death (you're welcome).  

It has new tubes (except for a couple preamp tubes that were in good shape and sounded great), and all the knobs work as intended.

The speaker cab is 4x10.  I currently only have a single Celestion Greenback installed in the cab and typically use a smaller 1x12 cabinet that weighs less than a gazillion pounds when I'm playing out.  The cab and amp both date to around October 1971, so they've been a pair from day one.
