Radial Mix-Blender Buffered Instrument Mixer & Footswitchable FX Loop Pedal

Radial Mix-Blender: Two Instruments, One Amp, Endless Blends

The Radial Mix-Blender is a buffered two-channel instrument mixer and footswitchable effects loop housed in a compact 14-gauge steel pedal. It sums two instruments or two pedals into a single output, each with its own Class-A buffered level control, and then routes that combined signal through a send/return effects loop with a unique wet/dry Blend knob. Designed for guitar, bass, and keyboards, it solves the age-old stage problem of running two instruments through one rig, and it turns your favorite effects into something you can dial in by the drop. Plug in, set your balance, and hear both voices finally sit together the way you always wanted them to.

How the Class-A Buffered Mixer Works

Passively summing two high-impedance instruments usually robs them of tone, because each source loads down the other and drains the high end. The Mix-Blender avoids this by placing a discrete Class-A buffer on each input, presenting a full 220 k-ohm load that keeps pickups and piezos sounding open and natural. The two buffered signals are then combined at unity in a low-noise summing stage that measures just 0.01% THD across a 20 Hz to 20 kHz response, so the blend stays clean and articulate. Individual level controls let you balance a hot humbucker against a quieter single-coil, or a bright acoustic against a warm electric, so neither instrument overpowers the other.

The Wet/Dry Effects Loop Explained

The heart of the Mix-Blender is its footswitchable send/return loop and the Blend control that governs it. Instead of running your pedals fully inline, where every bit of your signal passes through them, the loop taps a parallel path: your dry instrument tone continues untouched while a copy is sent to your effects, and the Blend knob mixes the returning wet signal back in at any ratio you choose. This is why heavily colored effects like fuzz, octave, or ambient delay never thin out your fundamental, because the dry core is always present underneath. A single footswitch engages or bypasses the entire loop, so a whole pedal chain can drop in and out in an instant.

Keeping Bass Full with Parallel Overdrive

Bass players face a specific problem: run a bass straight into a distortion pedal and the low end collapses as the drive circuit clips away the fundamental. The Mix-Blender's parallel loop fixes this directly. Send the signal to an overdrive or fuzz, then use the Blend control to add just enough grit on top of the untouched dry bass. The result is an aggressive, harmonically rich tone that still moves air, because the power and weight of the clean signal stay intact while the distortion rides above it. It is the same technique used on countless records, now available in one footswitchable box.

Built for the Realities of the Stage

With two inputs feeding one output, the Mix-Blender lets you connect two instruments and switch between them instantly, or play both at once through the same amp, which is ideal for a player who alternates between an electric and an acoustic mid-set. The send jack doubles as a tuner output, so you can mute and check your pitch without adding another box to the chain. Combining two pickups on a single acoustic often yields the most natural amplified tone, and the Mix-Blender lets you balance an undersaddle piezo against a soundhole or body-sensor pickup with precision. Everything is wrapped in a signature book-end steel chassis with recessed controls that shrug off the abuse of constant gigging.

Who the Mix-Blender Is For

This pedal is built for gigging guitarists who carry two instruments, acoustic players blending dual pickup systems, bassists chasing full-bodied parallel distortion, and keyboard players who want to fold effects into their sound without a full rack. Session and worship-team musicians use it to manage instrument changes on a crowded stage, while experimental players exploit the Blend control to sculpt textures that inline pedals simply cannot produce. If you have ever wished you could keep your true tone while still going all-in on an effect, the Mix-Blender is the missing link in your signal chain. Power it from any standard 9V DC pedal supply and it drops straight onto your board.
