TRADITIONAL BYPASS: True Bypass operation just like all Echodrives shipped originally from the factory.

ACTIVE TUBE / DELAY CANCEL BYPASS: The Echodrive is renowned for its High Voltage Tube Preamp. Numerous users leave it on all the time. However many wanted the ability to run through the Tube Preamp even when the Delay signal was bypassed. It's a wonderful sounding pre-amp, why let it go to waste! Hence we came up with the Active Tube / Delay Cancel mod, now available with the flick of the switch on the Echodrive 4.

SPILLOVER BYPASS: Previously our most requested Mod to the Echodrive. Over the last 15 years we have modified 500+ Echodrive pedals with this bypass option. This allows for the Mix Control Echo to trail off after bypassing while also creating a subtle extremely low level ambient like Echo in the background. Great for coming off a solo but then back into rhythm playing. In Spillover mode as with Active Tube mode, the High Voltage Tube preamp is always engaged.

Last but not least, the Drone features. SiB has always prided itself coming up with something different for musicians to expand their creativity in new ways. Delay and Echo lovers have always enjoyed these pedals for both the ability to add controlled and reserved Echo / Delay tones, or go into self-oscillation Echo / Delay madness. The new Drone feature enhances this by giving the user the ability to do that instantly one way or another when wanted. The Drone control adds extra repeats depending on where the control is set. The Drone switch is a Momentary switch. When depressed it gives the user the ability to infinitely repeat if desired, self-oscillate if desired for as long as one wants. Once the footswitch is released it instantly goes back to normal operation.

All of these new features found in the Echodrive 4 are off to the side of the original circuit thus preserving the original legendary and coveted Echodrive tone.
