The RGX 100 from Ghost Note Audio is a compact analog preamp pedal inspired by the high-gain Randall RG100ES, an amp known for its tight, aggressive tone. according to RockBoard's PedalPedia, players can shape a wide range of tones, from articulate high-gain rhythm to saturated lead textures, while maintaining the character of the classic RG circuit1. It sits among preamp pedals aimed at players who want an amp-style gain stage on a pedalboard.
What it does
The pedal takes the RG100ES circuit as its starting point and adds controls and modes that go beyond the original amp. A Tightness control allows for even sharper attack by trimming low frequencies in the early gain stages, which is aimed at keeping high-gain rhythm parts tight1.
A Crunch Mode introduces additional tonal flexibility by altering the bypass capacitors in the first gain stage, placing the sound halfway between the RG's two channels1.
The maker also describes an upgraded Sustain Volume feature that corrects the original amp's volume drop when engaging sustain mode, so switching into lead tones does not change the overall level1.
Power
The RGX 100 runs on 9V DC, center negative, and draws 180mA1. That current draw is higher than many compact pedals use, so it is worth checking what a shared power supply can deliver before daisy-chaining it with other pedals.
