From the vendor
The PedalPCB Arachnid is an FV-1 based digital multieffects pedal platform. Select between eight different high quality digital effects.
Three digital control parameters, analog dry signal path with wet/dry mix, and adjustable output volume capable of up to 6db boost.
NOTE: This item does not include an EEPROM. A compatible EEPROM must be purchased separately.
New Features! (2019 Edition)
• 8-position rotary switch for program selection
Program selection is now achieved with a 16mm 1P8T rotary switch instead of a standard potentiometer. This means better tactile feedback, aligning graphics with the switch positions will be more reliable, and no more need for the ATTINY microcontroller!
• Updated mix control
Updated mix control allows 100% wet, 100% dry, and anything in between with less volume drop in the middle.
• Improved signal path for lower noise floor
Improved filtering in the digital signal path lowers the noise floor without impacting tone.
Controls
• Control 1 – Digital parameter control
• Control 2 – Digital parameter control
• Control 3 – Digital parameter control
• Mix – Adjusts the Wet/Dry mix
• Mode – Selects the active algorithm
• Volume – Controls the overall output volume
Specifications
• Designed for a 125B enclosure with top-mounted jacks
