Passion for tone
Designing our amps was a true adventure, a quest for ultimate guitar tone.
Our goal: making the most awesome sounding, most durable and user-friendly tone-machines on the planet.
Our amps are made to inspire and have a truly unique character and feel, a delicate blend of
the perfect organic gain-structure, ‘punching’ frequency response, dynamic response, sustain and definition.

Maximum tone with minimum ‘bells and whistles’
Our amps are among the most versatile ones on the market yet extremely user-friendly.
Feature-wise all our amps are slimmed down to what you really need, which basically comes down to this:
awesome sounding amplifiers that are easy to use with features that are truly beneficial to you.

We believe durability is the key to sustainability. Therefore our products are extremely low maintenance and designed and build to last a lifetime. Over the years this will save you a lot of money on servicing and repair but it will also contribute to save the environment. We do our utmost to manufacture our products environmental friendly. We use *FSC certified wood, **RoHS compliant materials and production methods combined with a strict waste-management.
