Merlin – ’57 Tweed Champ

From 395,00

(4 customer reviews)


Providing warm tube sound, this little champ nails that authentic tweed amp tone, and is perfect for home practice, studio, or intimate gigs.

We used the original 5F2a Tweed Princeton schematic – which is basically a 5F1 Champ with an added tone control – and packed it into a beautiful tweed pine cabinet.

True to the original, the Merlin is hand constructed and soldered on eyelet board. We only used components of excellent quality, such as Sprague Orange Drop® capacitors, JJ® or Shuguang® Tubes and a Celestion® speaker.

This single-ended class A design delivers wonderful cleans at low to moderate volumes. When turned up, you are indulged with a unique touch-sensitive overdrive.

The Merlin amplifier is covered in expertly applied tweed covering, while the period-correct oxblood grille cloth and chickenhead knobs complete the aesthetic package for this little amp.

Just like the original tweed Champ, the Merlin uses a tube rectifier, which provides extra compression for that true vintage tone.

    Great amp, just one comment. When it arrived one of the lamps was detached, other than that, it’s a terrific sounding amplifier.
