Manufacturer Description
"A mythical overdrive meets the tone and feel of two iconic amplifiers. We have accurately recreated the circuit of the high headroom overdrive with the magic blend of clean and overdriven tones and added extra features for versatility. The amp-in-a-box section uses an all-analog circuit to capture the essence of two legendary D-style tube amplifiers. From tube-like compressed fat clean to sweet singing overdrive with blooming harmonic overtones. Combine both sides for near infinite smooth sustain and enter sonic bliss while a passive series effects loop gives you the option to connect your beloved pedals between the overdrive and amp section, building your ideal rig."
