For many, Clapton paved the way for rock guitarists with his blazing guitar work with John Mayall and the Bluesbreakers.  Moreover, many would argue his tone was just as important as his playing.

The Ceriatone JTM45 Bluesbreaker is based on the amplifier used on those recordings, and where it’s nickname originated.  It’s easiest to think of the Bluesbreaker as a JTM45, but with the addition of a fantastic bias-driven tremolo circuit.

Like other Ceriatone amps, we have labored carefully to select the finest components to suit the design, and the JTM45 Bluesbreaker uses our specially designed, custom transformers for superior reliability, frequency response, and feel.

Note: PPIMV mounted on Front Panel will be either mounted in place of pilot lamp (Marshall styles) or a hole will be drilled (OTS styles).
          PPIMV mounted on Rear Panel will always be in place of a Speaker Output Jack.
