Algorhythmo SBX1-D and SBX1-A — Both stompbox units together

Ships worldwide

01The System

Kick on the right. Snare on the left.

Plug the SBX1-A (Extension) into the SBX1-D (Main) to trigger two different sounds from the same unit. One foot plays the Main (e.g., Kick), the other triggers the Extension (e.g., Snare). With the built-in Guitar Passthrough, your guitar signal mixes with your beats and goes straight to your amp through one cable.

SBX1-D — Digital Main Stompbox
Digital

Stores 100 instruments internally. Map your favorite 10 directly to the hardware icons — LED indicators show instrument in use. Each instrument has 10 sounds to avoid the "machine-gun" effect, for authentic percussion sounds.

SBX1-A — Analog Extension Pad
Analog

Plugs into the SBX1-D to add a second trigger. Once connected, a new LED lights up on the main unit so you can assign a different instrument to each foot.

02Why We Built This

Current stompboxes are toys. This is an instrument.

Most digital stompboxes on the market sound like machine guns — same sample, same velocity, zero dynamics. We built the SBX System to fix that. It's the first stompbox with a dedicated Extension Unit and a Multi-Layer Engine that actually breathes. Every instrument ships with 10 velocity layers or variations, so your playing sounds alive.

Built by passionate musicians

Need more cowbell? We have it. Want to play loud EDM kicks live? Done. Most stompboxes sound thin when you try to play electronic genres. The SBX delivers 32-bit high-resolution audio, handling deep sub-bass and sharp digital snares without choking.
