The IdiotBox Effects Blackout is a fuzz pedal built around two Muff-style fuzz circuits running at the same time. As the maker puts it, "The Blackout is a double muff," and the two circuits are "Not one into the other, but mixed parallel," meaning both fuzzes see your guitar signal and their outputs are blended together rather than one fuzz feeding the next1. That gives you two independent fuzz voices in one fuzz pedal box, and the character of the combined sound depends on how you set the blend between them.
Controls and how the two circuits differ
Each of the two fuzz circuits has its own separate FUZZ, TONE and OUTput controls, so you can dial in one voice, dial in the other, and set how much of each reaches the output1. The tone stages are not identical:
- Top fuzz circuit: the traditional Muff tone control1
- Bottom fuzz circuit: more of a mid boost/scoop control in place of the standard Muff tone1
That difference is the point of the design. A conventional Muff tone control rolls off highs in a particular way, and players often note the mid scoop that gives the classic fuzz its voice. By giving the second circuit a mid boost/scoop control instead, the Blackout lets one side sit in familiar Muff territory while the other can be shaped to fill in or cut mids, and the parallel mix lets the two work together rather than one replacing the other1.
Power and bypass
The Blackout runs on a common 9 to 12V DC center negative BOSS style power input, the same connector type as most pedalboard supplies. A battery snap is included among its features, so it can run from a battery as well. IdiotBox Effects notes "Power supply not included," so you will need to bring your own supply1. The maker lists the current draw as "?mA," so no figure has been published for it1.
The maker lists the current draw as "?mA" on the product page, so if you are planning a daisy chain with other pedals, that figure is not published and you may want to power the Blackout on its own outlet1.
Switching is true bypass, so when the pedal is off it is removed from your signal chain1.
Size and price
The Blackout fits in a smaller 4.7" x 2.6" x 1.5" 125B sized enclosure, which is a compact footprint for a pedal carrying two complete fuzz circuits and six knobs1. The list price is $139.00 USD1.
The name: Blackout the pedal and Blackout Effectors
The Blackout's name can cause confusion with Blackout Effectors, a separate builder known for fuzz pedals of its own. The Blackout Effectors Musket Fuzz v2 is described by RockBoard's PedalPedia as "a best selling, highly tweakable, highly fuzzed-up iteration of the vintage muff-type circuit," and Aion FX describes it as "a unique and modern take on the Big Muff while retaining the character of the vintage circuit"23. Blackout Effectors also made the dual-fuzz Fix'd Fuzz Deluxe, of which Pedal of the Day's reviewer wrote, "Both of these fuzz channels are completely different in design and sound, making experimentation and mixing-and-matching" a major part of the appeal4. The IdiotBox Blackout is a different product from a different maker, but the shared idea of two distinct fuzz voices in one box runs through both.

Questions
Does the IdiotBox Blackout come with a power supply?
No. IdiotBox Effects states on the product page that a power supply is not included. The pedal runs on a common 9 to 12V DC center negative BOSS style power input, so a standard pedalboard supply works, but you will need to use one you already own or buy one separately.
Can the IdiotBox Blackout run on a battery?
Yes. The maker's product page lists a battery snap among the pedal's features, so the Blackout can be powered from a 9V battery as well as from an external DC supply. Note that a power supply is not included with the pedal.
Is the IdiotBox Effects Blackout true bypass?
Yes. IdiotBox Effects specifies true bypass switching on the Blackout, so the pedal is out of your signal path entirely when it is off.
What size is the IdiotBox Blackout enclosure?
The Blackout uses a smaller 125B sized enclosure measuring 4.7 x 2.6 x 1.5 inches, according to IdiotBox Effects. That is a compact footprint for a pedal carrying two complete fuzz circuits.
How do the two fuzz circuits in the Blackout differ?
The top fuzz circuit has the traditional Muff tone control, while the bottom one has more of a mid boost/scoop control in its place. Each circuit has its own separate fuzz, tone and output controls, so the two voices can be set and blended independently.
