The V-4 was never made into a combo amp, but however the VT-22 was and is essentially a V-4 combo amp, as far as the specs are concerned.

Here's a VERY rare opportunity to own a B-15S 15" extension cabinet. Most of the time you see cabinets that were stripped of the amplifier. This was manufactured as an extension cabinet. This is not an orphan cabinet from a complete amplifier. You can see its fitted with the original cups on top that the steel feet would sit in rather than having the shock mounts for the amp chassis. The cabinet is in original cosmetic condition however I am doubting the speaker is original. Its not very ... more

Up for sale is a 1965 Ampeg Gemini I project that was cut down to a head. It's in good condition and works good, but will need a pair of 7591 tubes and a tune up. Obviously, the reverb does work without a tank and the vibrato does not work also, however itt comes with the original footswitch and should be able to get up and working during servicing / It's missing the knobs which is how It ended up with it. They nicely cut down the cab, however no back panel.

A great example of a late 70s ampeg B100 bass amp. I got this amp from an amplifier technician who moved shortly after its purchase. This amp served me well as my main amp for years until unfortunately due to its old age a single capacitor blew making it smoke every time it turns on.
If you are experienced enough to change the capacitor then jump on this deal because theres not many of these gems around anymore and you won??t find a better deal.... more

These were some of the best tubes made back then and they still are today. ... more

This is a great set from when I parted out a bad SVT cabinet.

They are nickel chrome-plated and feature the unique Ampeg head that you need a special wrench for. But don't worry, a standard blade screwdriver fits snugly in the slot and gives you enough torque to fully tighten down your ... more
