EL84s are at the tonal heart of the HT-20R MkII combo and head. Decades of valve amp design experience combines the response and character of this classic British valve with a carefully voiced preamp to create wonderfully lush valve tones. From pure boutique cleans, to mild overdrive that cleans up by backing off the guitar volume control, right up to saturated distortion, this amp does it all. Simple and intuitive controls, combined with pro features like our patented ISF control, studio quality reverb, effects loop, XLR D.I. out and USB speaker emulated output, make them perfect for any performance situation – whether you're in the studio, gigging in front of a small crowd, or playing to thousands.
