The GUPtech FrAG Boost Gold Tone Rush edition is a metal boost pedal from GUPtech, the Quebec builder whose product pages describe it simply as a "Metal Boost by GUPTech"1. It is a special-look version of the company's FrAG Boost: GUPtech describes it as "Exactly the same circuit as the original GUPtech Frag, in a unique Gold box"1. In other words, the electronics are unchanged and what you are paying for, beyond the standard pedal, is the finish.
What it does
As a boost in the metal vein, the FrAG sits in the part of a board that pushes an amp or drives downstream gain pedals harder. GUPtech categorizes it alongside its other boost designs, a family that also includes the Slime Mid-Boost, the Le Chiou EQ-Boost and the Peeps Clean Boost1. If you are new to the category, the site's Boost Pedals page covers what boosts in general do to a signal.
The Gold Rush edition versus the standard FrAG
The only difference GUPtech draws between this and the regular FrAG Boost is the enclosure. The maker's own wording is that the Gold Tone Rush edition carries "Exactly the same circuit as the original GUPtech Frag, in a unique Gold box"1. Like the standard FrAG Boost, it is made by GUPtech in Saguenay, Québec, Canada1.
The Gold Tone Rush edition was listed as sold out on GUPtech's product page as of 26 October 20261.

Questions
Is the Gold Tone Rush edition different from the standard FrAG Boost?
According to GUPtech, the Gold Tone Rush edition carries exactly the same circuit as the original GUPtech FrAG Boost. The difference is the enclosure: the Rush edition comes in a unique gold box. So the choice between the two comes down to looks and availability rather than tone or circuitry.
Where are GUPtech pedals made?
GUPtech states that all of its pedals are made by the company in Saguenay, Québec, Canada, and the FrAG Boost Gold Tone Rush edition is no exception. It is a small-shop Canadian builder rather than a mass-production brand.
