Italian pedal manufacturer OPFXS has announced the Twin Boost, a stereo-output boost pedal that pairs an analog boost circuit with digital control, Guitar World reported on December 13, 20231. Guitar Pedal X had published its own account of the pedal on December 4, 2023, and reported that it was available for orders from the OPFXS web store at that time2.
The pedal is named for its dual mono and stereo outputs, which allow gain boosts to be sent to different amplifiers1. Guitar World reports it provides up to a 24dB push for driving tube amps, overdrives and distortions, and describes it as low-noise and high-output1. Guitar Pedal X describes the design as two +24dB clean, transparent analog boosts with digital control, and states that TRS cables enable pre/post boost, separate pedals or amps, and an FX loop insert, while a mono input provides only a mono output2.
A screen at the top left displays settings, where the gain boost and the rate at which it engages are viewed and controlled1. A control knob operates gain and preset transition changes, and presets can be saved and recalled via a footswitch1. Guitar Pedal X lists three presets (I to III) lit by red LEDs under the white knob, gain steps in 1 to 24dB intervals adjustable with the left footswitch, and a slew rate of 0 to 99 for transition timing2. It adds that F1, F2 and MIDI handle presets, channels, joint or separate operation and tip/ring selection, and that separate mode offers bypassed or independent channels with three presets per channel2. Guitar World reports that a separate channel mode effectively clones the pedal, with each channel featuring its own setting and preset controls1.
The pedal takes a standard 9V plug and has a printed QR code on its top surface linking to an online startup guide1. OPFXS calls it "a groundbreaking digitally-controlled analog booster" and says it has a "flat frequency response" and a "low noise floor even at very high settings"1.
"OPFXS's Twin Boost combines two +24dB, clean, transparent analog boosts with digital control."
Guitar World gives the price as approximately $1621.
