Mode 1: Clean
The gain setting starts at splendidly sparkling and dynamically clean. Beyond one o’clock the clean morphs into a clean sound with sweetly organic edge of breakup. Around three o’clockvery gradually the sound changes into a sweet and subtle 3d-crunch. The sounds of voicing 1 are best described as dynamic, three-dimensional, open and sparkling. It’s warm yet with good definition. Voicing 1 reacts perfectly to fuzz and boost pedals plugged into the front.

Mode 2: Super Lead
Like the original plexi, the overall sound is three-dimensional and open sounding with super tight bass response and very pronounced mids, yet without annoying hum-noises. Another huge benefit compared to the original circuit is the addition of the our acclaimed double master volume and SVC circuitry*. It adds enormous tone versatility ranging from ‘60’s 3rd stone from the sun’ all the way up to late ‘70’s eruptions’ and 'early 80’s back in black’. In addition it makes it possible for you to play at lower volumes without thinning up the tone or destroying the sustain. When the gain-pot is turned up, it is easy to ‘clean up’ with the volume-control-pot on your guitar, just like the original plexi's.

SVC -Seamless Volume Control- Tube amp volume under control!
As the ACE has both gain and master volume controls, it’s easy to find your sweet spot. In the SVC power section you’ll find an extra ‘total’ volume control. It enables the amp to produce 0,1 Watt bedroom levels yet retaining great tone. So from now on the power-soak is a thing of the past!
