Sale price$2,450.00


Overtone Joyful Music 50

Model Descriptions:

When people talk about “holy grail” guitar tones, there are names that inevitably come to mind for most guitarists.  Brilliant players like Jimi Hendrix, David Gilmour, Angus and Malcolm Young, Eddie Van Halen, James Hetfield, and Robben Ford have changed music as we know it not only with their undeniable skills as writers and players, but also with sonic signature.

One of such brilliant players is John Mayer.

While we have no affiliation with any of these players, their influence in our work can be seen to those attentive.

The Joyful Music! 50 is a clone of the amplifier largely responsible for Mr. Mayer’s amazing tone.  While this won’t get you an amazing collection of Rolexes, or help you date the most beautiful women on the planet…you’ll at least sound good!

Think of the JM50 as the mellow, wise brother to the SSS 50.  While the SSS is all about power, the JM has a similar signature but delivers it more sweetly (and less earth shatteringly loud).  The dynamics are a bit bouncier, more vintage-feeling.  Tonally, the two amps are somewhat similar, but the JM is much cleaner, a little sweeter on the high end, and has a more prominent midrange more similar to other OTS amplifiers.  The JM is also more stripped down in its features (and wiring), which equates to a bit more pure-to-the-guitar tone.

As with all Ceriatone amplifiers, we’ve obsessed over component selection, and it uses our specially designed, custom transformers for superior reliability, frequency response, and feel.
