The Ceres Preamp Drive is a pedal that is based on the Catalinbread Sabbra Cadabra, which is an adaptation of Tony Iommi’s signature tone from Black Sabbath. The pedal aims to recreate the sound achieved by putting a Rangemaster-style treble booster in front of a Laney Supergroup amplifier.

The control set of the Sabbra Cadabra is simple, with controls for pregain, gain, presence, and master volume. It can be used as both a preamp and an overdrive pedal, reacting to what comes before it. It can be placed after other drive pedals but before modulation effects. It can also be used as a standalone overdrive pedal.

The original Sabbra Cadabra used MPF4393 JFETs, which are no longer produced. However, Aion FX sells the original MPF4393 in sets of 5. The PCB of the Ceres also has an extra pad for surface-mount JFETs (MMBF4393), which are still in production and perform the same as the ones used in Catalinbread pedals.

The Ceres is compatible with the 18V Voltage Doubler / Bypass module, allowing the circuit to be run at 18V without an external adapter. This higher voltage provides increased volume and clarity.
