From bluesy overdrive to diabolical dirt box, the Maxon ST-9 Pro+ Super Tube is a devilishly diverse pedal that can punish a clean amp or turn a dirty amp into a wall of doom.


Bigger, Badder, Bolder – these are the best three words to describe the Maxon ST-9 Pro Plus Super Tube Pedal.

The latest and possibly last incarnation of Maxon’s legendary 808, the ST-9 features more output, more gain, and more tonal options for the player who simply needs – well, MORE.

Starting with a circuit loosely based on the classic 808 architecture, the ST-9 adds a Mid Enhance knob to control the amount of midrange boost.  This knob functions similarly to an amp’s presence control, boosting perceived volume and gain as it’s turned up.

You may be wondering why an 808-style pedal would need more presence – allow us to introduce you to the ST-9’s Low Boost switch. The Low Boost switch is the ST-9’s secret weapon – This unassuming switch completely changes the character of the pedal, adding beefy low end and increased saturation via a LP filter and an alternate set of clipping diodes.

If this wasn’t enough, the ST-9 also offers 9- or 18-volt operation via an internal charge pump.  Run at 9 for the classic 808 sound and feel or switch to 18 for increased headroom, improved dynamics, and a bigger, chunkier tone to the overdrive.

From bluesy overdrive to diabolical dirt box, the Maxon ST-9 Pro Plus Super Tubee is a devilishly diverse pedal that can punish a clean amp or turn a dirty amp into a wall of doom.
