All that musical might comes courtesy of the specially developed Ultra Response power amp. Cranking out up to 50 watts of deliciously dynamic power, its punch and feel rivals that of any similarly rated tube power amp. It sends every single watt to the speaker with that spine-tingling dynamic response intact and translated into impressive sound pressure. And the Ultra Response power amp stays true to its musical character even at an all-out roar.

For almost 40 years, we’ve been exploring the origin of the tonal magic of tube amplifiers more and more deeply. And what became obvious is this: it’s about way more than just the tube. The true tonal magic emerges from all the ‘weird’ dynamic interactions between the single circuit sections and the amp stages, the transformers and the speakers.

Together, these highly complex and dynamic physical phenomena create that rich, organic and tactile sound experience guitar players are looking for.

The Spirit Tone Generator technology faithfully recreates the natural yet wildly complex interactions of traditional tube amp circuits in a ‘bionic’ way. This miniature masterpiece distills the essence of tube amp physics, with all of the intensity and responsive tonal behaviour, into a compact, strictly analog circuit that promises unbridled playing pleasure.
