TUBELESS OVERDRIVE Feature #1 A drive pedal inspired by the sound character of the USA 30W amp that has captivated many famous artists. This is a completely limited production item that uses valuable parts and vintage parts that are no longer in production. TUBELESS OVERDRIVE Feature #2 The "Amplifier Matching Control" on the side allows you to control overtones, an important factor in guitar sound, and match the effect of TUBELESS with the sound of your amplifier. Of course, it can also be used as a control (which changes the sound even if it's not smelling it) for detailed sound shaping. Not only does it work well with clean tube amps, but it is also capable of outputting the finest tube sound when used with solid-state amps. TUBELESS OVERDRIVE Feature #3 By reducing the drive gain and increasing the output volume, it can also be used as a booster rich in harmonics. By using tubeless as a booster, you can further maximize the potential of your amplifier. At the same time, you can also control the sound projection even when the guitar volume is turned down. Recommended settings (Level 15, Gain 12, Tone 13, Side knobs full) TUBELESS OVERDRIVE Feature #4 The true bypass switch minimizes sound changes when bypassed. TUBELESS OVERDRIVE Feature #5 By using the simplest possible analog circuitry, we are able to directly reflect the guitar's original sound and the guitarist's expressiveness. Please experience its dynamic range and sound clarity for yourself. TUBELESS OVERDRIVE Feature #6 A completely original aluminum die-cast heavy-duty body designed by a professional designer. It boasts outstanding durability to withstand harsh use in professional settings. others You can use a commercially available (BOSS, MAXON, etc.) center-negative regulated 9V-10V AC adapter. This minimizes the difference in sound between using a battery and an adapter, a common concern with overdrive pedals.Condition: No problems with use. Parts requiring acknowledgment: None.
