TomKat pedals TomKat Super Heavy

The TomKat Super Heavy is a stereo digital pedal that chains three effects in one box: delay, then overdrive, then reverb. Designed by Tom Kogut of TomKat pedals, it launched in December 2024 and was reported by Delicious Audio as his first release in five years¹. The builder describes the design as inspired "by the most powerful rocket ever launched by humans"¹.

Where many multi-effect pedals treat each block as an equal, the Super Heavy puts the reverb first: Delicious Audio calls the reverb "the most important and therefore tweakable effect in this circuit"¹. The pedal is made by TomKat pedals, whose Tom continues to turn out new designs¹. Alongside the reverb, the circuit includes delay and overdrive elements².

What it does

The signal runs through the three blocks in a fixed order: delay first, then drive, then reverb¹. Because the whole chain is stereo, a player can feed two amps or a stereo interface and keep the width of the delays and reverbs intact. One thing to know before buying a power supply: there is no analog dry-through, so the dry signal passes through the conversion too, and the pedal's rear panel takes 9V DC at a reported 350mA, which rules out a battery and makes a daisy chain with other pedals risky².

The pedal stores 7 factory and 7 user presets, so a player can recall saved delay, drive and reverb settings rather than rebuilding a sound from scratch¹.

The controls

The face of the pedal is organized around a central knob and a set of smaller controls that light up in four colors, each color standing for one part of the chain. Turning the central knob selects and edits one of the three effects, or the parameters that affect the entire output, with the color coding showing which effect is being tweaked at that moment. Pressing the central knob enters Presets mode¹.

Guitar Pedal X breaks the four color-coded clusters out as follows²:

The Universal cluster is where the overall balance lives: input and output gain at the ends, and individual mix levels for the delay, drive and reverb blocks in between³.

Two footswitches sit at the bottom of the pedal:

• Left footswitch: a momentary Freeze function that freezes the wet signal¹. Guitar Pedal X describes it as an Infinite Freeze / Pads function, useful for holding a wash of reverb and delay under your playing².
• Right footswitch: engages and bypasses the pedal².

The Freeze function is the performance feature here: hold the left switch and the effects signal sustains while you play dry lines over the top, a common trick on ambient and pad-style reverb pedals¹.

Where it came from

The Super Heavy comes from TomKat pedals, the small maker whose Tom, as Delicious Audio puts it, "is still churning out pedals"¹. Delicious Audio's coverage highlights where the pedal's priorities sit, describing the reverb as "the most important and therefore tweakable effect in this circuit"¹. Guitar Pedal X covered the launch and the pedal's place among that year's new spatial and time-based effects²³.
