So sorry for the late reply! It's been a busy holiday season here at TWA and we're now just about caught up. Are you able to hear the effects at all? Does your guitar have the built in Fishman System?
It may be worth trying a new battery in the Fishman system or a different cable between the guitar and the TWA.
If you continue to have trouble, shoot us an email at firstname.lastname@example.org and we'll help you figure it out!
