The T-Rex Binson Sterephonica is an analog stereo drum delay from T-Rex built around a magnetic wire wrapped moving drum, which the maker describes as "just as the original." Alongside its echo voices, it offers a Swell mode for reverb-like sounds, and it runs on 24V DC with a 350mA current draw. The reviewer verdict quoted on the announcement was blunt: "This is every way a perfect execution - possibly bar its size and price."1
What it does and how it is controlled
The Sterephonica carries two record heads, labeled Slow and Long, which read and write to the moving drum to set up its delay structure. An Echo Tone control adjusts the color of the delay, shaping how dark or bright the repeats sit in the mix. A Swell mode produces reverb-like sounds, a use the original Echorec was also known for. Speed can be controlled by expression pedal, so the drum speed can be swept by foot for pitch-bending, tape-style shifts while you play.1
The 24V DC, 350mA power requirement rules out a standard pedalboard supply or daisy chain. Plan a dedicated 24V output on your power supply.1
Connections: XLR, line and MIDI
This is where the Sterephonica parts company with most delay pedals. It is built to sit in a studio or a professional rig as comfortably as on a board:
- XLR inputs: XLR Left In and XLR Right In1
- XLR outputs: XLR Out Left and XLR Out Right1
- Line outputs: Out Left and Out Right on conventional jacks1
- MIDI: MIDI In and MIDI Out1
The XLR ins and outs mean it can be patched directly into an interface or console without a DI box, and MIDI In and Out let it sit under the control of a MIDI controller or switcher alongside the rest of a rig.1
Where it came from
The Sterephonica's drum design is the heart of where its sound comes from: a magnetic wire wrapped moving drum, which T-Rex describes as "just as the original." The pedal also carries a Swell mode for reverb-like sounds, extending what the drum mechanism can do beyond straight repeats. Power needs are substantial for a pedal, at 24V DC with a 350mA current draw, which is worth planning for on a pedalboard supply.2
The Sterephonica is a separate, larger stereo unit announced in January 2026. It is not the same product as the earlier mono T-Rex Binson Echorec Magnetic Disk Delay.13
What reviewers said
Guitar Pedal X's Stefan Karlsson, writing at the announcement, summed the unit up this way1:
"This is every way a perfect execution - possibly bar its size and price."
The size and price caveat is the honest counterweight: at roughly $3,000 USD and studio-oriented dimensions, it is aimed at players for whom the Echorec sound is worth a serious outlay, not a first delay pedal.1

Questions
Is the T-Rex Binson Sterephonica analog or digital?
It is analog. Guitar Pedal X describes it as an analog stereo drum delay based on the Binson Echorec, and like the original it uses a magnetic wire wrapped moving drum rather than digital processing to produce its repeats.
Does the Sterephonica use a real spinning drum?
Yes. Guitar Pedal X reports that it uses a magnetic wire wrapped moving drum, just as the original Binson Echorec did. T-Rex's earlier Binson Echorec pedal likewise uses a custom alloy drum with a spinning mechanism, described by the maker as delivering vintage tone with modern reliability.
Does the Sterephonica have XLR connections?
It does. The rear panel carries XLR Left In and XLR Right In, plus XLR Out Left and XLR Out Right alongside conventional Out Left and Out Right jacks, which makes it straightforward to run into a studio interface or a stereo rig.
What power supply does the Sterephonica need?
It runs on 24V DC, center negative, drawing 350mA. That is a higher voltage and current draw than most standard pedal power supplies provide, so it needs its own supply rather than a daisy chain.
Can the Sterephonica's speed be controlled with an expression pedal?
Yes. Guitar Pedal X lists expression pedal controllable speed among its features, so you can sweep the drum speed by foot while playing.
How much does the Sterephonica cost?
Guitar Pedal X describes a price of roughly $3,000 USD as appropriate, and notes that the unit was available for preorder at a few select dealers as of January 2026.
