http://www.loop-master.com/product_info.php?cPath=34&products_id=169 Echoplex Footswitch: Get full control over all functions of your EP-2, EP-3 or EP-4 Echoplex tape echoes with one pedal. (*Not for use with the Gibson/Oberhiem Digital Pro models etc..**) Select "Bypass"to completely remove the Echoplex from your signal chain. Echo On/Off lets you turn the echo off but still take advantage of the Echoplex's great buffer. Recording/Playback lets you playback something you recorded on the fly. All functions do not have to be hooked up. For example, if you just wanted to use it as a bypass box for the Echoplex, just use the loop part of the switcher. (In, Out, Send, Receive) Or if you only wanted to control the Sound On Sound (Playback) and/or Echo On/Off etc.. just connect those sections up only. Unit will work without power minus LED indication. Can also be used as a stand-alone single loop effect switcher for any effect that you want to bypass. Dimensions: 4.7" X 3.7" X 1.1" box enclosure. Built with Switchcraft jacks, heavy-duty switches, military spec. wire, and silver soldering throughout. LEDS: For the 9V DC Jack, these units require a 9V AC adapter with a Boss/Ibanez style 2.1mm barrel plug. If you do not have one, we have these in the "Accessories" section. (The LED circuit in any Loop-Master pedal does not affect tone.) All leds: Blue http://www.loop-master.com/product_info.php?cPath=34&products_id=170 Footswitch for the Fulltone Tube Tape Echo: Footswitch for the Fulltone Tube Tape Echo (TTE). Controls "Playback" and "On'Off" functions. Dimensions: 4.37" X 2.37" X 1.22" Comes with blue leds **You must use a stereo (TRS) cable for this pedal to hook to the TTE. The TTE manual calls for the use of the highest quality stereo cable you can find to reduce signal loss. We have access to these cables if you need one. Email us with your required length and I will get you a quote. Also, if you have little or no use for the "Playback" feature, you can use a standard guitar cable into the TTE and this switcher. Or, just use one of our standard Channel/Effects Switchers into the TTE with a standard guitar cable if you aren't ever going to use the "Playback" feature on the TTE.
