An overdrive pedal that boosts internally to 150V and features a 12AX7 (ECC83) vacuum tube. It has a warm sound unique to vacuum tubes and can also produce a sharp drive sound. ■ Details 1. This model is a refined version of the vacuum tube OD previously used in the collaboration pedal (limited edition) with TS developer Mr. Tamura and idea sound product, equipped with JJ Electronics' low-noise/high-reliability vacuum tube, and further refined for ease of use. 2. The DC9V power supply is boosted internally to 150V and supplied to the vacuum tube. The unique circuit configuration fully expresses the characteristics of the vacuum tube. ■ Specifications DC INPUT: DC9V center negative (power supply of 400mA or more) GAIN: Adjusts the amount of distortion. TONE: Adjusts the high/low frequencies. BASS: VOLUME: Adjusts the volume. INPUT: Input impedance 1MΩ OUTPUT: Output impedance 100Ω FootSW: The LED turns off when off. In that case, it becomes true bypass. BrightSW: Adjusts the ultra-high frequencies. On when up. TUBE: The vacuum tube installed is 12AX7 (ECC83). A DIP switch is installed inside, and you can access it by opening the bottom plate. ※ Be sure to turn off the power before opening. When set to MidBoost, the mid-range is significantly boosted. ※ The default position of the SW is no boost. The operating voltage of the vacuum tube is 150V. To avoid electric shock, always turn off the power (remove the DC plug) when opening the bottom plate. ※ The photos are all samples. The serial number and design may differ slightly. ※ Handmade effectors may have minor scratches or paint unevenness.
