The GUP Tech Dude Screamer is a handmade boutique overdrive pedal, part of the Canadian maker's range of overdrive pedals. GUP Tech describes its gain as ranging from low tube-style gain to high saturation, so it covers everything from a light push to a fully saturated drive sound in one box. The pedal is listed at a regular price of £131.00 GBP, with a sale price of £109.00 GBP shown1.
Controls
The Dude Screamer keeps the layout simple: three knobs and two switches.
| Control | What it does |
|---|---|
| Volume | Sets the pedal's output level |
| Drive | Sets the amount of gain, from low tube gain to high saturation |
| Tone | Shapes the pedal's treble response |
| Fat switch (left side) | A boost, mounted on the left side of the enclosure |
| Clipping toggle | Selects the clipping character, see below |
The clipping toggle is the pedal's most distinctive control, offering three positions1:
- Left: asymmetrical silicon clipping
- Middle: bypass, which GUP Tech describes as giving more dynamics
- Right: 5mm red LEDs as the clipping elements
The left position of the clipping switch selects asymmetrical silicon clipping. The middle position is bypass, which GUP Tech describes as giving more dynamics. The right position selects 5MM red LEDs clipping. GUP Tech does not publish sound clips or reviewer quotes for this pedal, so the descriptions above are the maker's own1.
Circuit origins
GUP Tech states that the Dude Screamer is "Based on a very popular pedal that we don't need to name here"1. The maker leaves the origin circuit unnamed on the product page, and the pedal's Lawn Green styling is listed as its variant style1. Players comparing it with the well-known green overdrives it evokes can read more in the Boss SD-1 vs Ibanez TS9 Tube Screamer comparison. GUP Tech builds several other takes on classic drive circuits, including the PHNX Overdrive and the Horsie Overdrive.
Power and practical details
The Dude Screamer runs from a standard 9V adaptor with a DC output and negative center pin, the common arrangement for guitar pedals, so it works with a typical pedalboard power supply1. The pedal uses a true bypass design, so its circuit drops out of the signal chain completely when off1. A 5mm green water clear LED shows when the pedal is engaged1.
GUP Tech publishes a quickstart document for the pedal as a downloadable PDF from the product page, covering setup and operation1.

Questions
What does the Fat switch do on the GUP Tech Dude Screamer?
The Fat switch is a boost mounted on the left side of the pedal. GUP Tech lists it as part of the pedal's control layout alongside the Volume, Drive and Tone knobs, so it gives the player an extra level of push on top of the main overdrive controls. It is a toggle rather than a knob, so it works as a set-and-forget option rather than a footswitchable effect.
Is the Dude Screamer true bypass?
Yes. GUP Tech describes the Dude Screamer as having a true bypass design, meaning the pedal's circuit is taken out of the signal path entirely when it is switched off. The pedal also has a middle position on its clipping switch that GUP Tech labels Bypass, which the maker describes as offering more dynamics.
What pedal is the Dude Screamer based on?
GUP Tech says the Dude Screamer is based on a very popular pedal that the company does not need to name here. The maker's own page leaves the origin circuit unnamed, so the pedal is presented as a boutique take on a well-known overdrive design rather than a licensed copy of any specific model.
What power supply does the Dude Screamer need?
The Dude Screamer runs from a standard 9V adaptor with a DC output and a negative center pin, which is the common standard for guitar pedals. GUP Tech describes it as compatible with a standard 9V AC adaptor with a negative center DC output, so a typical pedalboard power supply output or one-spot style adaptor will run it.
Does the Dude Screamer come with a manual?
GUP Tech provides a quickstart document for the Dude Screamer as a downloadable PDF from the pedal's product page, so the documentation is available online rather than only in the box. The quickstart covers the pedal's controls and operation.
