We’ve done many Tele’s – on guitars with the output jack mounted on a plate in the edge of the body, you can usually remove the jack plate and slide the Redeemer into the hole directly behind the jack. Then all you have to do is find room for the battery inside the control cavity. Most tele’s have a flat bottom cavity which is no problem for the battery, some tele’s have a ridge of wood in the bottom of the cavity in which case you could either remove the ridge, or adapt the Redeemer to a smaller camera battery – As long as the Redeemer has at least 3.6V it will be happy – it can go as high as 18V.
