The MOD102+ expands on the same all analog vacuum tube classic American circuit design combined with a British style Class A output section as the Original MOD102 with some much added special “+” features. These special features include a three position progressive toggle switch for off-standby-power and additional push-pull functionality for each control - pull out the bass control knob for “mid boost”, pull out the treble control knob for “bright”, pull out the volume control knob for “turbo”. These new features and a JJ ECC803-S (a long plate 12AX7 known for its complex mid range tones) allow for a wider variety of tones and extra control for the user.
