Thermion Zero Pedalboard Amp


Here's what Thermion say about the Zero pedalboard amp:

Zero is the portable amp that lets you play live, rehearse, or practice at home just with your pedals. We have created Zero for those guitarists who love analog and realistic sound and don't want to use digital emulators.

Thanks to our own Class D hybrid power technology, with two real 40 watt outputs, we have reproduced the behavior of a tube amp's transformers and all of their harmonics. Zero has a clean analog preamp, stereo effects loop, stereo reverb and a preamp loop, so you can switch between its internal preamp and your own.

All emulated outputs equip our 'Analog Speaker Modeling' technology, which recreates the behavior of a real speaker cabinet using only analog circuits, to retain all the dynamics of your tone. Thermion Zero is the hybrid revolution of simplicity and portability. Open up a whole new world of possibilities for your pedalboard with Zero.
