Booteek Amps: Handmade by Marshall Heiser


Booteek amps are located in sunny Brisbane, Australia. I handcraft every amplifier and cabinet myself, one at a time, adopting time-honoured construction techniques and using only the best materials available today. Though inspired by classic tube combos I have known, owned and loved over the years, booteek amps brings a new twist to these designs to better serve the needs of the 21 century musician. Last, but not least, I familiarise myself with each and every amp after completion, playing it in and meticulously quality-checking before releasing it out into the wild.

About the Amp

It’s MAMA BOO….warmer than a Champ….louder than a Princeton….more versatile than a Deluxe! Featuring all the rich harmonic detail and touch responsiveness of a single-ended, class A circuit, paired with a 6L6-optimised power stage and feeding a colossal Hammond 125ESE output transformer. In addition to that 10 Watts of pure tone, she’s housed in a resonant and rattle-free, solid-pine cabinet with a 12 inch speaker. Don’t talk back to Mama!

This premium-quality, hand-wired, all-tube amplifier was inspired by a desire to find an mid-to-small size combo capable of both crisp, clean tones and creamy overdrive…and all at levels suited to a variety of playing environments. No expense has been spared with regard to component selection and attention-to-detail craftsmanship.
