PRISONswitch

Engineered for musicians who demand reliable remote control and clear status feedback for their amplifier's built-in effects circuits. PRISONswitch simultaneously engages or disengages onboard tremolo and reverb while giving immediate visual confirmation during performance.

Status

Prototype Footswitch Digital Control

Switch Operations

Hold / On-Off / Expression

A robust dual-switch architecture independently controls two effect circuits, with potential double-click support for new modes.

Monitoring

Pedal Statistics

Hold both switches down to view pedal statistics, including switch count and held-time behavior.

Microcontroller

ESP32-S3 Platform

Built around the Xtensa® 32-bit LX7 dual-core microprocessor with 2.4 GHz Wi-Fi and Bluetooth® 5 LE.

Core Functionality

Control Beyond Basic On-Off

Switch operations: supports hold, on-off, and expression functionality, with a potential double-click feature for new modes.
Performance monitoring: hold both switches down to view pedal statistics, including how many times the pedal has been switched or how long it has been held.
Microcontroller power: ESP32-S3 family architecture showcases advanced microcontroller skills and future-proof wireless integration.
Easter egg: hold the switch for 10 seconds to discover the hidden strobe effect.

Prison Variant Design Ethos

Sophisticated, No-Blinking Aesthetic

Transparent housing: the flagship Prison variant uses a completely clear acrylic housing that exposes the internal digital circuitry and mounted components.
Premium materials: the enclosure is accented with brushed metals and set in brushed steel screws.
Visual feedback: status is provided discreetly through a transparent 1.51-inch blue OLED screen with 128x64 resolution and SSD1309 driver chip.
Profile: designed with a low, flat profile.
