125B · 6 knobs
From the vendor
FV-1 based digital multieffects platform with onboard USB EEPROM programmer.
Three digital control parameters, analog dry signal path with wet/dry mix, and adjustable output volume.
Difficulty
Moderate – Some SMD soldering is required as well as the use of command-line utilities to flash / convert EEPROM data. It’s not rocket surgery, but also not an absolute beginners project.
Controls
• Control 1 – Digital parameter control
• Control 2 – Digital parameter control
• Control 3 – Digital parameter control
• Mix – Adjusts the Wet/Dry mix
• Mode (toggle switch) – Selects the active algorithm
• Volume – Controls the overall output volume
Compatibility
The FV1Dev has been tested on Microsoft Windows 10 (1803), Apple macOS Sierra, Apple macOS Mojave, and Ubuntu 18.04.1 LTS. Other versions may work, but have not been tested by PedalPCB.
Specifications
• Designed for a 125B enclosure with top-mounted jacks
