The Ghost Note Audio Omega Lead is an analog preamp pedal built around the circuit of the Sunn Beta Lead, the amplifier it takes as its model. according to RockBoard's PedalPedia, its CMOS distortion stage generates harmonically rich distortion, which an active EQ with wide-range controls then shapes, so the pedal works as both a drive and a tone-shaping preamp in one box1. It sits in the preamp category alongside other Ghost Note Audio pedals such as the ICBM, RGX 100, Century and 8100 Gold, and alongside the wider field of preamp pedals.
What it does
The Omega Lead reproduces the preamp section of the Sunn Beta Lead in pedal form. RockBoard's PedalPedia describes the signal path in two stages: a CMOS-based distortion circuit that produces harmonically rich distortion, followed by an active EQ circuit whose controls have an extremely wide range, letting a player cut or boost well beyond what a passive tone stack allows1. For a player, that means the pedal can go from a mild push to a full voiced lead tone, with the EQ able to reshape the distortion rather than only trim it.
Power
The pedal runs on 9V DC, center negative, and draws 180mA1.
At 180mA, the Omega Lead draws more current than many standard pedalboard power supplies deliver per output, so a supply with sufficient current per output is worth confirming before adding it to a daisy chain.
