The GUPtech Jojo Cake is a distortion and fuzz pedal handmade in Saguenay, Quebec, Canada. GUPtech describes it as a disto/fuzz unit that covers a wide range of drive tones, from smooth creamy distortion to over the top saturation, both with what the maker calls a huge bunch of sustain1. It sits in the territory shared by distortion pedals and fuzz pedals, and it is part of the Jonny Rock by GUPTech line, the former Jonny Rock Gear designs that GUPtech has built by hand since November 20241.
What it does to your sound
GUPtech's own description frames the Jojo Cake as a pedal that gets many shapes of tones from smooth creamy distortion to over the top saturation1. In practice that means one footswitchable circuit that moves from a sustained, creamy drive voice into full fuzz-style saturation as you turn up the Icing control, with the Sugar tone control shaping the top end and Size setting the output level1. Players looking for a single box that covers both distortion and fuzz territory is exactly the use the maker describes.
Controls
The three-knob layout keeps the pedal simple: set the level with Size, dial in how hard the circuit is pushed with Icing, and shape the tone with Sugar1.
Power and bypass
The Jojo Cake takes a DC output with negative center polarity and is compatible with a standard 9V AC adaptor, in GUPtech's wording1. That is the common center negative standard, so it works with typical pedalboard power. The pedal uses a true bypass design, so your signal is untouched when it is off, and a 5mm LED indicator shows when it is engaged1. The enclosure is powder coated die cast aluminum1.
The listed price is £107.00 GBP as stated on the maker's page dated 26 October 20261. No US dollar price is given.
Where it comes from
The Jojo Cake belongs to the Jonny Rock Gear line. Since November 2024, all Jonny Rock Gear pedals have been handmade by GUPtech in Saguenay, Quebec, Canada, and are branded Jonny Rock by GUPTech or JRG by GUPTech1. GUPtech describes the takeover as keeping the same tone and same circuits, with some little enclosure changes to accommodate its new building methods1. GUPtech builds its wider range of pedals there too, including the Pumpky Distortion, the Double Donut and the 1982 Douche Edition1.
Pink edition
Beyond the standard powder coated enclosure, GUPtech offers the Jojo Cake as a custom pink edition. The maker's page describes picking out a very cool custom pink JoJo cake with a special message on the side1, so the enclosure can carry a personal message.

Questions
Is the GUPtech Jojo Cake true bypass?
Yes. GUPtech lists the Jojo Cake with a true bypass design, so when the pedal is off your guitar's signal passes straight through without going through the circuit. The pedal also has a 5mm LED indicator so you can see at a glance whether it is engaged.
What power does the GUPtech Jojo Cake need?
The Jojo Cake runs on a DC output with negative center polarity and is compatible with a standard 9V AC adaptor, in GUPtech's wording. That is the usual center negative pedal supply, so a standard pedalboard power supply or one-spot style adaptor fits. The pedal has no battery option listed.
Where is the GUPtech Jojo Cake made?
GUPtech builds the Jojo Cake by hand in Saguenay, Quebec, Canada. The company states that all of its pedals are made by them there, and since November 2024 that has included the former Jonny Rock Gear pedals, which GUPtech now builds under the Jonny Rock by GUPTech or JRG by GUPTech name.
What do the Size, Icing and Sugar knobs do?
The three controls follow the pedal's baking theme. Size is the volume control, Icing sets the amount of distortion, and Sugar is the tone control. Between them they shape the pedal's range from smooth creamy distortion to over the top saturation.
Was the Jojo Cake originally a Jonny Rock Gear pedal?
Yes. Since November 2024, all Jonny Rock Gear pedals have been handmade by GUPtech in Saguenay, Quebec, and are now branded Jonny Rock by GUPTech or JRG by GUPTech. GUPtech says the pedals keep the same tone and same circuits, with some little enclosure changes to suit its new building methods.
Does the Jojo Cake come in a pink edition?
It can. Alongside the standard powder coated enclosure, GUPtech offers the Jojo Cake as a custom pink edition, described on the product page as picking out a very cool custom pink JoJo cake with a special message on the side. That makes it one of the few pedals you can order with a personal message on the enclosure.
