GUPtech Saguenay Drive

The GUPtech Saguenay Drive is an overdrive guitar pedal made by GUPtech in Saguenay, Québec, Canada¹. GUPtech describes it as "perfect to push an already crunchy amp for more and more gain, even pushing a Marshall JCM800 into the classic Trash territory"¹. In other words, it is built as a gain-stage booster and overdrive in front of an amp that is already breaking up, rather than as a clean-boost-only box.

The circuit is a tribute rather than a new design: GUPtech states plainly that "Our Saguenay Drive is based on the original 1981 Boss SD-1"¹. What GUPtech adds is a set of modern build features on top of that vintage circuit.

An overdrive based on the Boss SD-1 circuit

The Boss SD-1 Super OverDrive, made by Boss, expanded on the OD-1 design with enhanced voicing and a tone control². GUPtech describes its Saguenay Drive as based on "the original 1981 Boss SD-1"³⁴, and TONEHOME describes the SD-1 as using "the same asymmetric overdrive circuit as the OD-1"⁵. Guitar.com's Cillian Breathnach characterizes the SD-1 as "The brand's take on a Tubescreamer-style mid-hump soft-clipping overdrive"⁶.

That family tree tells an experienced player a lot about what to expect from the Saguenay Drive: soft clipping rather than hard clipping, a midrange push rather than a scooped sound, and a character suited to pushing an amp rather than creating distortion on its own. For a beginner, the short version is that this is the same style of overdrive as the classic green Tube Screamer and SD-1 boxes that sit in front of countless amps⁶¹⁷.

GUPtech's own framing of the pedal's job lines up with that lineage. The maker positions it as a pedal for players who already have some amp gain and want more of it, up to and including high-gain territory¹.

What GUPtech changed

The Saguenay Drive keeps the SD-1 circuit but updates the hardware around it. GUPtech lists these modern features¹:

• Top-mounted jacks, which save width on a pedalboard
• True bypass, so the signal passes through untouched when the pedal is off
• Solid Alpha or equivalent potentiometers

The true bypass point is worth noting for anyone comparing it with the original: Boss's own pedals traditionally use buffered bypass rather than true bypass, so this is one place where the Saguenay Drive deliberately departs from the pedal it honors. For more on the effect type generally, see overdrive pedals¹⁴⁷.

Power and practical details

The Saguenay Drive runs on 9V DC with a center negative plug, the same standard as most modern pedals, and draws 6mA¹. That low draw means it is easy to run from a shared pedalboard supply alongside other low-current analog pedals.

The standard Saguenay Drive is listed at £71.00 GBP by the maker in October 2026¹.

The Saguenay Dry limited edition

The pedal's name is a pun with local roots. GUPtech explains that the Saguenay Dry was a locally made ginger ale, and the company pays tribute to it: "Today, we are doing an hommage to the original name and colour scheme of the Saguenay Dry by using the puns to turn it into the" Saguenay Drive, whose initials match the SD-1 circuit inside⁴.

That homage took physical form in the Saguenay Drive Overdrive - Douche Edition, a super limited chrome-green edition carrying the ginger ale's color scheme⁴. It shares the same circuit and features as the standard pedal, including the top jacks, true bypass design, and 9V DC center negative power⁴.

Where it sits among GUPtech's overdrives

GUPtech makes a range of overdrive and preamp pedals alongside the Saguenay Drive, including the CocoCast Preamp-Overdrive and the Queen of Crow Dual Overdrive, which also received a limited Spooky 2026 edition. The Saguenay Drive is the company's SD-1-based entry in that lineup, where the Queen of Crow offers two overdrive circuits in one box and the CocoCast takes a preamp approach.
