Up for Sale is a Vintage 1960's Cordovox Tube Amp & Tone Generator !

 Accordion / Guitar Amp! Made In USA!

This is really cool. You are looking at a Vintage 1960's Cordovox Tube Amp & Tone Generator. Designed as a Accordion Amp, these also make a great guitar amp. So what exactly is this?
From The Web:  
CORDOVOX CG TUBE AMPLIFIER. or more precisely, tube amp AND tone generator. Research shows the amp is rated at 30W, using TWO sylvania and RCA 7591 power tubes, and TWO 12AX7 preamp tubes (that look to be telefunkens!). The tone generator uses 60 (yes – SIXTY!) tubes (6X8 and some other kind that aren't useful for guitar amps), not including six other preamp tubes (a mix of 12AU7 and 12AX7 tubes, some branded Mullard, Lafayette, RCA, and a couple i'm unable to discern the name off). The 2 speakers are TRUE vintage C12R Jensens, dated in 1964.
Back up: what the heck is a tone generator?

Let me first preface that in the 60s, CMI (Chicago Musical Instruments) had several brands under its name, such as Gibson (for high-end guitars), Maestro and Kalamazoo (for their economy line), and Cordovox, for accordions.

Accordion manufacturers at the time (1960s) are scrambling to compete against the skyrocketing popularity of electric guitars. They tried to follow the concept of plugging in an electric guitar to an amplifier, but it was not easy to amplify an accordion back then (other than to simply mic it). Unlike electric guitars that simply had at least one pickup for all 6 strings, each chord on an accordion had to have its own tone bank that had to be amplified. In this particular Cordovox model (CG), this resulted in using at least 4 up to 6 vacuum tubes EACH chord. For a full octave (12 notes or chords), 60 tubes had to be used. These tubes had to be housed in a cabinet called a TONE GENERATOR, same size as the SEPARATE cab that housed the amp section and the two 12″ speakers.

The tone? USEFUL and BEAUTIFUL! With a MASTER volume dimed, you can dial in the loudest CLEAN this amp can push at 30W, just back off the mic volume to about 10 oclock. Dial past that and you start overdriving the sound nicely, and diming it produces a gritty distortion that has bluesy sustain. Another cool thing about it? keep the mic volume dimed but back off the master volume, and you have bedroom levels that retains that overdriven tone!

This amp really does sound awesome. It can be converted to just a guitar amp with some work. Right now you just plug into the tone generator and it sounds just fine. You do have to have both the amp and the tone generator and the cable to make this work. You can convert this to a single 2x12 combo amp. There are a lot of conversions listed on the internet. This Auction is for the Cordovox Tube Amp, Tone Generator and the Cables. (The amps in the background are NOT part of this sale).


Footswitch NOT Included
Complete Package with Amp, Generator and Cable!

Everything functions and works fine!

Cosmetics: Excellent Condition. I don't think that there is much playing time on this Cordovox. Keep in mind that this is a 55+ year old vintage amp. Normal wear and tear. It is used. Not perfect. Look at the pictures closely. They will tell the story.
