A new feature that has been incorporated into our pedals for the last 6 months plus is a new form of low-power latching relay bypass that reverts to bypass when/if power is lost. The latching relay only consumes power when changing state, but a clever switching circuit uses a pre-charged capacitor to reset the relay when/if power is lost.
This feature is also being incorporated into the next batch of EchoVerberator pedals. The EchoVerberator is a buffered bypass effect that reverts to true bypass via the relay if/when power is lost. Giggity.
