The Engine's unique synergy of dynamic overdriven foundation tone combined with a sparkling Range boost will give you a huge sonic world to explore. It consists of two fully Analog sections. Side A is very carefully tuned to capture the sound, feel and dynamic response of a real 60's British non-master-volume amp. You can easily get that cranked Tube-like distortion sound but without the need to play at ear-shattering levels. Side B's most powerful feature Range is our take on the Treble Booster from the 60's. Besides that, the high headroom and distortion-free Clean Boost and versatile Low & High EQ will help you even further in tailoring your tone. Stacking these A&B sections (A to B or B to A) with the Order switch can yield numerous combinations of incredibly rich sounds.
