Ground Control Audio announces the Tsukuyomi Midrange Booster

A simple but effective tone-sculpting tool.

Ground Control Audio Tsukuyomi Midrange Booster

Fresh out of Ground Control Audio’s corner is the Tsukuyomi Midrange Booster. The pedal is modelled after the brand’s popular Amaterasu Bright Pre-amp, and features a dedicated midrange boost that shapes tone in a unique way.

Like how a samurai slices through enemies with a katana, this stompbox is designed to cut straight through the mix. It borrows two elements from the Amaterasu pedal: a JFET frontend and a 20dB gain amplifier stage.

With the “Mids” switch to the right position, the pedal acts as a volume boost. But flick the switch over to the left, and the 880Hz to 1kHz frequency band gets a 12dB boost. This gives your lead tones the right amount of push to stand out in the mix. The overall effect is governed by a “Gain” knob.

As you would expect, the Tsukuyomi reacts differently to various pickups. Ground Control Audio recommends a single-coil and trebly amp setup for some “velvety fullness”, or, if you’re partial to humbuckers, a “crunchy sweetness”.

Retails at $159. More information at
