The T-Rex TwinBlaze is a two-channel tube distortion pedal designed and assembled in Denmark, built around a real 12AX7 (ECC83) triode preamp tube. T-Rex describes it as capturing "the soul of a roaring tube amp and brings it to your pedalboard," and says it channels the spirit of classic amp stacks like the JCM45 and Mesa Boogie1. It sits in the maker's distortion line alongside pedals like the T-Rex Mudhoney and T-Rex Dr. Swamp, and belongs to the broader family of distortion pedals.
The TwinBlaze is listed as sold out on T-Rex's webshop as of October 20265. It is a 12V pedal drawing 500 mA, so it will not run from a shared daisy chain or an output that cannot supply 12V at that current.
The controls and footswitches
The TwinBlaze carries three footswitches: channel A, channel B and boost. Guitar.com's reviewer Richard Purvis called it "this three-footswitch stomper" in his August 2026 review4. Both channels offer Crunch and Lead modes, giving four gain voices across the two channels1.
Each channel has a control array that follows the Marshall JCM800 template: preamp gain and output level plus bass, middle, treble and presence4. That is a fuller EQ section than most distortion pedals carry, and it means each channel can be dialed in as its own amp-style voice rather than sharing one tone stack.
The third footswitch engages a dedicated 20dB clean boost. T-Rex says the boost preserves your tone, adding volume and presence without coloring your gain, which makes it a solo or volume-lift footswitch on top of the two channels1.
Outputs and recording
The TwinBlaze offers both a standard output for amp setups and a speaker simulation output for direct recording or live mixing1. The speaker-simulated output lets the pedal go straight into an audio interface or a mixing desk without a mic'd cabinet, which is where a tube preamp pedal with a real 12AX7 differs most obviously from a conventional distortion or overdrive box.
What reviewers said
Guitar.com's review of the TwinBlaze concluded that "the TwinBlaze nails every aspect of its brief, and you don't have to be an 80s diehard to appreciate the quality of its" tones4. The reviewer's overall verdict:
"the TwinBlaze nails every aspect of its brief, and you don't have to be an 80s diehard to appreciate the quality of its"
Purvis also placed the pedal in context for the maker, calling it "part of an expanding range of homegrown pedals from a company that used to be pretty much all-in on Chinese production"4.

The TwinBlaze is a current product page on T-Rex's site with product number #102102, but the webshop lists it as sold out as of October 20265. An English manual for the pedal is available through RockBoard's PedalPedia entry3.

Questions
Does the T-Rex TwinBlaze use a real tube?
Yes. T-Rex fits the TwinBlaze with a high-grade 12AX7 (ECC83) triode tube, the same preamp tube type found in guitar amplifiers, and describes it as delivering authentic warmth and dynamics. RockBoard's PedalPedia entry likewise lists it as a tube-driven overdrive/distortion built around the 12AX7A.
What power supply does the TwinBlaze need?
The TwinBlaze runs on a 12VDC supply with a 2.1mm barrel plug, and T-Rex includes one with the pedal. It draws 500 mA at 12VDC, which is well beyond what a standard 9V pedal output on a typical daisy-chain supply provides, so plan your power accordingly.
Does the TwinBlaze have a speaker simulation output?
Yes. Alongside a standard output for amp setups, the TwinBlaze offers a speaker simulation output intended for direct recording or live mixing, so you can run it straight into an interface or front-of-house without a microphone on a cabinet.
What amps is the TwinBlaze modeled on?
T-Rex says the TwinBlaze channels the spirit of classic amp stacks like the JCM45 and Mesa Boogie. Guitar.com's reviewer Richard Purvis noted that each channel's control array follows the Marshall JCM800 template, with preamp gain and output level plus bass, middle, treble and presence.
Is the T-Rex TwinBlaze still available?
The TwinBlaze is listed as sold out on T-Rex's webshop as of October 2026. The pedal remains on the maker's product pages, so it may return, but it cannot be ordered at the moment.
