Maxon ST-9Pro+ Super Tube Pro Plus is a bigger, badder, and bolder 808 Tubescreamer-like overdrive pedal. It 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 drive 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.

The Low Boost switch is the 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 pedal 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 ST-9 is a devilishly diverse pedal that can punish a clean amp or turn a dirty amp into a wall of doom.

Maxon Guitar Effects

Maxon Guitar Effects is a Japanese company best known for designing and manufacturing high-quality guitar pedals, particularly overdrive, distortion, and fuzz pedals. Originally established in the 1960s as part of the Nisshin Onpa Co., Maxon initially produced pickups and eventually moved into effects pedals, working as an OEM (Original Equipment Manufacturer) for major brands, including Ibanez. The company became particularly famous for developing and producing the iconic Tube Screamer overdrive pedal for Ibanez, one of the most influential and widely-used pedals in guitar history.

Solid build quality and analog warmth

Over the years, the company developed a strong reputation for innovation, often pioneering new effects circuits that became industry standards. Their pedal designs emphasize tonal clarity, durability, and analog warmth, appealing to both vintage enthusiasts and modern players. Maxon’s effects pedals are highly regarded for their build quality and sound, with many musicians and collectors seeking out both vintage models and newer reissues for their reliability and distinct sound. Today, Maxon produces a range of pedals under its own brand name, including overdrive, distortion, delay, chorus, and other effects. While still relatively boutique, Maxon’s pedals have a dedicated following among professional musicians and tone enthusiasts worldwide.
