MOOER DELAY D7 Mod. External Switch Modification I think it's amazing that this small body can also have memory. To make it easier to use, I asked an effector workshop to modify it with an external switch. You can turn it ON/OFF with an external footswitch using the mini-jack on the front. For example, you can set it at the back of your effector board, or if it's a slatted type, you can install it on the back. It can be connected with a general unlatch footswitch (*). * BOSS FS-5U, and others for tap tempo, etc. I think even inexpensive footswitches will be okay. Since it's a mini-jack, convert the SW side to a mono standard. The cable can be stereo or mono, it doesn't matter. Body only, no box or manual. No operational problems. Velcro on the back. There are a few small scratches, but it's in good condition. This is a great deal because it includes the body and modification costs. Instant purchase OK. (Ships on weekdays.
