From Old Blood Noise:

What began as a simple request for a vocal version of an Old Blood effect spiraled into a multi-function device with 10 new effects, versatile in/out and send/return sections oriented toward any instrument you want to throw at it, and ample control over all elements. It’s the new multi-tool for effects lovers on stage and in studio.

• XLR preamp for use with microphone level signals
• Switchable saturation section with blend, volume, and tone controls
• Two independently controlled effects sections with modulations, delays, reverbs and octaves, and controls over mix and two parameters of each
• A send/return to patch in external effects
• Post-saturation dry output for mixing versatility
• Relay bypass switching with momentary or latching functionality and effects trails
• Standard 9VDC center negative power
