Perfect for anyone looking to add subtle or dramatic movement to their sound without complex routing.

Frequently Asked Questions

No, it requires a standard expression pedal input that provides power. It's designed specifically for those connections, not for arbitrary CV control.
No, it's a linear attenuator. While it provides adjustment, it won't offer the same level of nuanced control as a logarithmic pot would.
Yes, 5V falls within the supported 3.3V-9V range, but performance may be slightly reduced compared to higher voltages. Check your pedal's documentation.
