The RED JASPER RJ-1V by Free The Tone is a low-gain overdrive pedal designed to provide sensitivity and responsive tone with a natural and comfortable compression feel. It features carefully chosen high reliability components and a passive type tone circuit (hi-cut) to minimize phase error in the guitar signal. The pedal also includes a mode switch to select low-end frequency characteristics from four settings, allowing users to adjust the lower register output to suit the characteristics of their guitar or amplifier. Additionally, it has an astoundingly excellent signal-to-noise ratio and implements Free The Tone’s original HTS (Holistic Tonal Solution) circuit to maintain sound and low noise while preventing degradation of guitar timbre even when the effect is turned off.

- Input Impedance: min. 390 kΩ
