The Furukawar Effects Temple of Doom Fuzz is a compact analog fuzz pedal built around a single knob and a diode toggle switch. RockBoard's PedalPedia describes it as "a simple, no-BS fuzz pedal" capable of producing a range of sounds, from a low but clear rumbling drive tone to a fat, rich fuzz, with various options in between1. Writing at Pedal of the Day in 2015, reviewer Mike B called it "just a solid, fat fuzz that will enhance your tone and cut through any mix you want to throw at it"2.
Controls
The pedal keeps its face simple: one knob and one switch.
| Control | What it does |
|---|---|
| Volume knob | Controls the volume, which simultaneously adjusts the amount of grit and fuzz1 |
| Toggle switch | Alternates between Silicon and Germanium clipping diode selections, allowing for further tone customization1 |
Because the lone knob doubles as the gain control, turning it up brings in more grit and fuzz along with more level. The toggle switch is the only other sound-shaping option, and Mike B noted it is "almost hidden in the shiny silver enclosure"2, so it is easy to miss at first glance.
The diode toggle: Silicon versus Germanium
The toggle switch alternates between Silicon and Germanium clipping diode selections1. Those are the two classic diode types used in fuzz and distortion circuits, and each clips the signal in its own way, so flipping the switch gives two distinct flavors of fuzz from the same box. The maker frames it as allowing further tone customization1.
Power
The Temple of Doom Fuzz runs on 9V DC, center negative, and draws 4mA1. That is a small current draw by pedal standards, so it fits comfortably on a shared power supply with the rest of a board.
What reviewers said
Pedal of the Day reviewed the pedal on 12 June 2015, when it was the maker's flagship and currently only available pedal2. Mike B's verdict was positive on the pedal's simplicity as much as its sound:
"I really, really dig this fuzz, the simplicity, the easy controls and most importantly the sound."
He described it as simple to dial in, with easy controls and a strong sound2.

Questions
What power supply does the Temple of Doom Fuzz need?
The Temple of Doom Fuzz runs on a 9V DC supply with a center negative plug, the standard arrangement for most pedalboard power supplies. It draws 4mA, a very small current draw, so it sits comfortably alongside other pedals on a shared supply without straining it.
Is the Temple of Doom Fuzz analog?
Yes. The pedal is an analog circuit, according to the maker's product information. That matters to players who prefer the way analog fuzzes respond to picking dynamics and guitar volume changes, and it means there is no digital conversion anywhere in the signal path.
What does the diode toggle switch do on the Temple of Doom Fuzz?
The toggle switch alternates between Silicon and Germanium clipping diode selections, giving two distinct clipping characters from the same circuit. The maker describes this as allowing further tone customization, so you can flip between the two diode types to shape how the fuzz breaks up.
Does the Temple of Doom Fuzz have a tone control?
No. The pedal has a single knob, a Volume control, which simultaneously adjusts the amount of grit and fuzz along with the level. There is no separate tone control; the diode toggle switch is the only other sound-shaping option on the pedal.
