The GUP Tech BOF is a multi-effect pedal that puts two overdrives and a digital delay in one enclosure. GUP Tech builds it from three of its own circuits: the PHNX Overdrive, the 1982 overdrive/distortion, and the KSTR digital delay. The maker describes the result as "a Swiss knife adding two overdrives and an ambiant delay to your board in only one enclosure."1 For a player, that means three pedals' worth of gain and delay on a board without three separate boxes, in the same spirit as other GUP Tech multi-circuit builds like the Blades of Steel Triple Overdrive.

The three circuits inside

Each section of the BOF is a pedal GUP Tech also sells on its own, so a player can hear what each part contributes before deciding how to use it1:

The maker's own words carry the idea behind the pedal:

Jack sets and the loop

The BOF is wired around two jack sets rather than a single input and output. PHNX and 1982 sit on the first jack set, and KSTR sits on the second, with center jacks forming a loop between them.1 The BOF Douche Edition uses the same arrangement, with the center jacks serving as an internal loop.2 In practice, that layout lets a player run the two gain stages and the delay in the order the enclosure is built around, or use the loop jacks to place other gear between the sections.

Power and practicalities

GUP Tech specifies 9Vdc center negative power for the BOF, with a power consumption of 42mA.1 That draw is worth noting for players powering a board from a daisy chain, since it is higher than a simple single overdrive typically needs. The same 9Vdc center negative requirement applies to the Douche Edition.2

The BOF draws 42mA, a figure GUP Tech lists under power consumption, so a standard pedal power supply with enough headroom is worth checking before adding it to a daisy chain.1 GUP Tech lists the pedal at £178.00 GBP.1

For a quick reference on what the maker specifies:

  • Power: 9Vdc center negative1
  • Current draw: 42mA1
  • Build location: Saguenay, Québec, Canada1
  • Pickup: GUP Tech shop, 6182 Boulevard Talbot, Saguenay QC G7N 1W1, usually ready within 24 hours1

Colors and the Douche Edition

The standard BOF comes in three color options: green, yellow and pink.1

The BOF Douche Edition is a custom special edition unit from GUP Tech, and the maker's page lists it as sold out as of 26 October 2026.2

GUP Tech has a running habit of Douche Edition special versions of its pedals, typically limited runs in distinctive enclosures, and the BOF followed that pattern with its own custom unit.2 With the Douche Edition sold out, the standard BOF in its three colors is the version currently available from the maker.12

Questions

What is inside the GUP Tech BOF?

The BOF combines three GUP Tech circuits in one enclosure: the PHNX Overdrive, the 1982 overdrive/distortion, and the KSTR digital delay. GUP Tech describes the result as a Swiss knife that adds two overdrives and an ambient delay to a board in only one enclosure.

What power does the GUP Tech BOF need?

GUP Tech specifies 9Vdc center negative power for the BOF, with a power consumption of 42mA. That is more than many single overdrives draw, so it is worth keeping in mind when planning a daisy chain or choosing a power supply.

GUP Tech builds the BOF in Saguenay, Québec, Canada. The maker states that all of its pedals are made by the company there, and local pickup is available at the GUP Tech shop on Boulevard Talbot in Saguenay.
