Hand-Built British Craftsmanship

The PM-20C is a hand-built, all-valve combo amplifier that combines the core features of the PM-20H head with the convenience of the 1x12" Celestion Creamback-loaded cabinet. Crafted in the UK, it embodies the spirit of British boutique design, offering professional-grade tone in a portable, self-contained package that's ready for studio, rehearsal, or stage.

All-Valve Power and Dynamic Response

At its heart, the PM-20C is powered by 2x 6v6 output valves, producing smooth compression, rich harmonics, and touch-sensitive tone. With 20 watts of output, it strikes the perfect balance between volume and natural overdrive, making it ideal for small venues, studio recording, or at-home practice. From shimmering cleans to warm crunch and saturated drive, the PM-20C responds musically to every nuance of your playing.

Intuitive Controls and Tonal Flexibility

The front panel keeps things intuitive with Gain, Bass, Middle, Treble, and Master controls, giving players all the tonal shaping they need without unnecessary complexity. A two-channel design allows seamless movement between clean and driven tones, while the channel-linking function opens up new tonal textures by blending both channels. With these tools, the PM-20C makes sculpting your ideal sound effortless and inspiring.

Boost, Voicing, and Creamback Power

For extra punch, the Boost function - accessible via panel switch of FS-2 footswitch - provides a clean lift or subtle drive for solos and dynamic passages. A Dark/Light voicing switch adds even more flexibility, offering two distinct tonal characters: Dark for warmth and depth, Light for bite and clarity. Paired with the Celestion Creamback 12" speaker, renowned for its punch mids, smooth highs, and tight lows, the PM-20C delivers classic projection and definition with unmistakable character

Studio-Ready and Built to Last
