Vemuram Jan Ray style [Demo Video] https://youtu.be/LT5LzJ-32P8?si=PW4qgVsbdLFOeh_w [Product Description] Equipped with a vacuum tube: ECC83 (12AX7) and supplies power boosted from 9V to 180V. It has a wide dynamic range, excellent responsiveness to guitar volume adjustments, and directly conveys the nuances of string touch and picking. Lowering the Drive knob produces a shimmering clean tone. Increasing the Drive knob gradually transforms into an aggressive vacuum tube overdrive sound. The Sparkle/Normal switch emphasizes the high frequencies of the pre-gain, resulting in a sharp sound. Lowering the Treble and Bass knobs allows for sound shaping focused on the mid-range.
