Hiwatt - Custom SA20-H

The Hiwatt Custom 20H is a tube head designed for guitarists who want an amp that's responsive, expressive and easy to play. Constructed in Class A cathode bias, it delivers Hiwatt's legendary clean tones, precise and detailed, while revealing rich, natural overdrive at moderate volumes.

Unlike more powerful models, which maintain a clear sound even when very loud, the Custom 20 invites you to push the gain to explore harmonious, dynamic textures, perfect for expressive playing or saturated passages.

Operation is intuitive and flexible. The Hi and Low inputs adapt to the characteristics of each guitar, enhancing dark pickups or tempering bright highs.

The three-band EQ is highly effective, to the point of being considered a real instrument in its own right, allowing you to sculpt the sound with precision.

The push/pull gain potentiometer provides a transparent boost that enriches the signal from the preamp, while the Bright switch adds brightness to clean sounds or tightens the treble on saturated sounds.

The Custom 20H remains very much alive under your fingers: its natural compression reacts to the nuances of your playing, and it interacts perfectly with effects pedals. Its compact size and contained power make it an ideal ally for the studio or intimate stages.


The build quality guarantees reliability and durability. English Partridge™ transformers, point-to-point wiring to Harry Joyce military standards and an 18mm birch plywood chassis ensure a solid rig.

This amp reveals the personality of each guitar and adapts to the musician's playing, offering a clear, dynamic and modular sound that is easy to set up and enjoyable to use every day.
