The Photon Booster / Line Driver is a pedal that is based on the Seymour Duncan Pickup Booster (version 2). This version, which was traced by Aion FX in 2019, features a true class-A output stage. The original version of the Pickup Booster was traced in 2007, but the updated version had not yet been dissected by the DIY community.

The purpose of the Pickup Booster is to provide a clean and transparent 25dB boost to your signal. It is designed to be used as the first effect in your signal chain, as it directly interacts with your pickups. If it is not used as the first effect, the Resonance switch may not function as intended and may only act as a slight treble cut.

One of the unique features of the Pickup Booster is its resonant peak switch. This switch allows you to adjust the sound of a single-coil pickup to sound more like a vintage or high-output humbucker, depending on the setting.

The Photon Booster / Line Driver is essentially a direct clone of the Pickup Booster, with the only modification being some additional power supply filtering. This ensures a clean and stable power supply for the pedal.

Overall, the Photon Booster / Line Driver is a faithful adaptation of the Seymour Duncan Pickup Booster, offering a versatile and transparent boost to your signal.
