The Maxon ST-9 Pro+ Super Tube Pedal stakes a big claim for being one of the most sonically customisable overdrive pedals ever invented. The secret behind this incredible functionality and tone lies in the design which was loosely based on the late 70s OD-808, just with some major upgrades.

The Mid Enhance control lets you vary the amount of iconic mid-boost that Maxon overdrives provide, while the Low Boost switch allows a rumbling low-end response with increased saturation thanks to an alternate set of clipping diodes. Add to this, the pedal can operate at either 9V or 18; run at 9V for the classic 808 sound or switch to 18V for increased headroom, improved dynamics, and thicker, chunkier overdriven textures.

AD-900 Analog Delay

In 1994, one Bill Finnegan (and two engineers from MIT) sat down and created the Klon Centaur, one of the most talked-about circuits of all time. While it was at its core an overdrive circuit, it boasted several innovations that put it ahead of the rest of the stuff out there. For one, it included a robust power supply that provided a theoretical 27 volts of headroom from a nine-volt supply. Perhaps more notably, the Centaur thrust the idea of dual-gang potentiometers into the groupthink of pedal development. While these weren’t cutting-edge tech in 1994, very few pedals utilized them. In fact, the Shin-Ei Uni-Vibe is one of the only popular pedals I can remember using one (C100K in fact).

AD9Pro Analog Delay

The AD10 takes Maxon’s 30+ years of experience in analog delay design and offers it up in one compact, WYSIWYG pedal.

The AD10 delivers up to 600 milliseconds of gorgeous, organic delay that doesn’t get in the way of your original guitar tone.  Delay repeats are tuned to perfection with a subtle yet distinct distortion and none of the high-frequency whistle associated with over-clocking of the delay circuit.
