■The legendary overdrive MAXON ST9 was released in the 1980s and is still talked about as a vintage effect even though it is no longer in production. The ST9Pro+ (Super Tube) is a reborn version of the original ST9 with a new circuit.

■The mid-range boost control reproduces a powerful, heavy sound like a stack of amps. The drive control also allows for a wide range of settings, from booster-like settings to blues sounds and hard rock sounds.

■The new 2-pair diode clip and low-frequency boost circuit allow you to select even stronger distortion and low-frequency boost.

■The internal operating voltage can be selected from 9V and stabilized 18V. The new circuit boosts the voltage to 18V with the internal DC/DC converter only when 18V is selected. When 9V is selected, the internal DC/DC converter does not operate at all and the unit operates on the voltage supplied directly from the battery or AC adapter. When using batteries, the internal DC/DC converter does not operate, so the battery life is improved.

■By setting the internal operating voltage at 18V, sufficient dynamic headroom is ensured, unintentional distortion is significantly reduced, and stable, high-quality sound is always obtained.

■The unit employs TBS (True Bypass Switching) with a 4PDT mechanical switch. When bypassed, the unit is in a completely bypassed state that does not pass through any electronic circuits. Even when using effects, the sound does not pass through electronic switching circuits, so there is no deterioration in sound quality. This TBS is extremely popular with many musicians and guitarists.
