Easy install and works flawlessly. I am so glad this became available and I was able to get this. It takes my amazing EF-X2 mkii to another level. Thank you for help with the sale as well. Appreciate it!!

It's a DIY kit, but the instructions from the Echofix team were clear and comprehensive. I took my time and in about 30 mins I was up and running again. Shane was very helpful in getting me the right match of Kit for my configuration. The end result is significant increase in the capability of my EF-X3R. Highly recommended.

Awesome. Very fun to play with these.

Not sure why they use potentiometers instead of switches. I can never tell where the point on the pots rotation is that they kick on and off, so I don't have precise control.

The effect is amazing with these mods though. Really can't get enough.

Wouldn't mind having these available via foot pedal or some kinda external control (even on the front of the device) with an indicator light because I find myself using these a lot.

Can you tell us what bias and formula tape you use so we can make our own loops shorter and longer?
