Key facts
Input impedance> 1M Ohm @ 1KHz1
Power60mA current draw @ 9VDC1

The T-Rex FuzzTopia is a hybrid fuzz and distortion pedal: two complete circuits in one enclosure, each with its own footswitch and its own set of controls. T-Rex describes it as "a hybrid between retro fuzz and warm distortion," and says it "can go from the nastiest thunderstorm to the sweetest, smoothest distortion without losing its character."1 It is designed and handmade in Denmark, and T-Rex frames it as "a tribute to the sound that began with a studio accident in the '60s and still inspires us today."1

Two circuits, three sounds

The FuzzTopia's layout is built around independence. Each section carries the same four controls, and the two footswitches operate independently, controlling each effect separately.1

ControlWhat it does
Fuzz / DistortionGain for its own circuit: fuzz on one side, distortion on the other1
ToneTone shaping for that circuit1
BlendMixes clean and distorted signal for that circuit1
VolumeOutput level for that circuit1
Footswitch (x2)One per circuit; each operates independently1
Rear toggleLinks both effects for simultaneous on/off, or separates them1

Guitar.com's reviewer, Richard Purvis, described the result: "two circuits in one box with separate footswitches means instant access to three sounds: left, right and both at once."2

A push-button on the back handles 'individual/both' switching. T-Rex's product page describes a rear toggle switch that links both effects for simultaneous on/off, or separates them for individual use.1 Purvis noted that this lets you turn both circuits on and off simultaneously with either footswitch.2 Each circuit also has backgrounds that light up when the relevant channel is engaged.2

The Blend control

The Blend knob is the pedal's distinguishing feature. T-Rex calls it "the unique Blend control, which is a new feature on a fuzz pedal," and says it "lets you mix clean and distorted signal for dynamic tonal shaping, from subtle crunch to full-blown chaos."1 Each of the two circuits carries its own blend, alongside gain, tone and volume.2 For players familiar with fuzz pedals and distortion pedals as separate categories, the idea is that you can keep low-end and clarity from the clean signal underneath the affected one, rather than committing fully to either.

Build, power and size

Purvis found the build solid: "the metal enclosure feels rugged, and the knobs are recessed to protect them from your clumsy hooves."2 The pedal is not valve-powered and runs off a standard 9V power supply, which he noted as a practical advantage.2

T-Rex's specifications for the pedal:

  • Power: 9VDC, 2.1mm barrel plug1
  • Current draw: 60mA1
  • Input impedance: greater than 1M Ohm @ 1KHz1
  • Size: 2.36 x 4.45 x 4.61 inches (W x H x D), including knobs1

The 60mA current draw means the FuzzTopia needs a supply with headroom; a low-output daisy-chain output may not carry it alongside other pedals. No battery option appears in the maker's power specification.1

The FuzzTopia draws 60mA at 9VDC, so a standard 9V supply handles it, though a daisy chain shared with other pedals needs enough headroom for that draw.1 Its list price was £129 (€149/$189), which puts it in the mid-price range for a fuzz pedal.32

What reviewers said

Guitar.com's review gave the FuzzTopia a rating of 7. Purvis's verdict was mixed. On the positive side2:

  • He called it "a compact two-in-one solution at a great price"2
  • He found the distortion sounds really nice at lower gain levels2

On the critical side:

  • He described the fuzz as quite spitty and hard to tame2
  • He judged it not the most elegantly designed stompbox2
  • He characterized the fuzz side as more gnarly Maestro FZ-1 than purring Tone Bender2
  • He found the tone control softens the midrange but does nothing with the piercing treble2

Questions

Can you run both sides of the T-Rex FuzzTopia at the same time?

Yes. The two footswitches operate independently, so you can run the fuzz and the distortion separately, and a rear toggle switch links both effects so they switch on and off together. Guitar.com's reviewer noted that two circuits with separate footswitches gives instant access to three sounds: left, right and both at once.

Does the FuzzTopia take a battery?

The maker's product page lists power as a 9VDC supply with a 2.1mm barrel plug, and Guitar.com's review notes the pedal is not valve-powered and runs off a standard 9V power supply. No battery option is listed, so plan on a 9V DC centre-negative supply with at least 60mA of current.

What does the Blend knob do on the FuzzTopia?

The Blend control mixes clean and distorted signal for dynamic tonal shaping, which T-Rex describes as ranging from subtle crunch to full-blown chaos. T-Rex calls the Blend control a new feature on a fuzz pedal, and each of the two circuits has its own.

Where is the T-Rex FuzzTopia made?

T-Rex states that the FuzzTopia is designed and handmade in Denmark. T-Rex is a Danish effects maker, and the FuzzTopia is described by the company as a tribute to the fuzz sound that began with a studio accident in the 1960s.

How big is the T-Rex FuzzTopia?

T-Rex lists the pedal's size, including knobs, as 2.36 x 4.45 x 4.61 inches (W x H x D). Guitar.com describes it as a compact pedal that houses two circuits with separate footswitches.
