Are you selling, keeping, or just inquiring?
Ampeg V-series are unique amps. Out-of-the-ordinary tubes and design give them their own tone. The 3-way rocker switches above almost every knob on the things (and the circuitry behind the switches) makes them very versatile, you can get a mind-numbing array of sounds from them. They came in head, 212 (like yours) and 410 configurations (like mine.) Rated at 40 watts, they are nonetheless LOUD. Also heavy- at least the 410 is- it's biggest drawback.
There were about three generations- top-loaded, front loaded, and front-loaded with master volume and/or distortion controls. Generally, TL's are more desirable than FL's, and the master vol./distortion models the least desirable. But, similar to the lore that has sprung up around blackface Fender amps, it seems the actual differences in the three generations are far less than the rumors would have us believe, and all V's can be easily modified, being point-to-point wired.
Ron Wood ('Stones) and a famous somebody much more current like them, or did at one time. I don't think there were every any celeb. endorsements.
Right before the current recession,
a VT-40 sold on eBay for $1,050. Now, you will be lucky to get half that, but if you sit on yours, the value should recover, unless the vintage amp market was a "bubble," which is very likely. Time will tell.
The vt-40's are probably more collectable than the heads or 22's, but the 22's are probably more usable and gigable, due to the 40's absurd weight (my 40 easily out-weights any of the Fender Twin Reverbs I have owned.)
Hope that helps.
I wanted to sell
my VT-40 (front load, no dist. or master volume,) and even had a member here ready to buy. Shipping hassles and general life delayed the sale, and he bought another one. Frankly, I am glad it happened that way. Mine now sits in my son's recording and rehearsal studio in New Orleans, and will soon be played by a famous guitarist from a current band that is, ahem, "angry with the equipment..." (and that's all I'm gonna say about that.)
Where do you live, Zim?
