This is the final version of the Lickliter XD120. What a killer amp! I had a blast making this clip and video. This all tube amp has a 6550/EL34 combo in the power amp which is my favorite combo. Every tube has its own bias control so you can easily swap tubes to find your perfect combination. In addition to the high gain channel featured here, this amp has a great clean channel. I will have a clip of that coming shortly.
