JMK/THcustom Epic Looper - with video
« on: June 21, 2019, 06:25:19 PM »
This is my implementation of the venerable JMK/TH Customs Epic Looper. This is such a fantastic loop switcher! Not just a great DIY loop switcher, but great period. It goes as far as you can go in functionality while staying completely simple. And itís so compact! I think everyone should build one. Now, if you want something that goes way beyond epic and space isnít a concern, take a look at Marshall Artsí Eoo3 project. Everyone else, build the Epic Looper.

I went a little off the reservation with this one in terms of making it my own. Here is a list of things I did that strayed from the build report:

- soft touch switches
- separate LEDs for programs/loops (vs bicolor LEDs)
- 7 segment bank display (This actually is an option provided by Jacob and Thomas but itís a little more work to build)
- extensive use of 3D printed parts to get everything to fit and mount. I also used 3D printed drilling guides
- custom printed/cut vinyl graphics by my friend Forest at Dukes Decals.

For more info on how I built it, check out the WIP thread.

Thanks for looking!

The inside of that looks like a server room.
 ;D 
Nice work, inside and out.
Love the super clean labeling.
Technical difficulties in abundance.  Please stand by.  ;-)

Are those relays(?) inside the box the same color as the blue on the outside?

Thanks friends. It feels good to have it done and the only troubleshooting was reversed leads on the MIDI pins.

Good point. I guess they are. That was unintentional. Funny thing about those relays; there was something super satisfying about getting the relay board populated. It was so easy to do but when it was done I kept staring at it because it looks so good. And it feels really substantial.

Looks really great!

Could you share what switches you used and if they were a direct replacement for the switches from the BOM, please?

Thanks! The switches are the soft touch momentaries from BLMS. The kit is not designed to work with them. Circuit-wise they are just fine but the kit is designed for DPDT switches to directly mount to daughter boards which in turn hold the indicator LEDs. To make these work I had to fabricate my own mounting solution for the daughter boards and LEDs. I donít recommend it unless you have a 3D printer and know how to do 3D modeling. The switches from the BOM work great. They have a nice feel and only a slight mechanical click.

We designed it with you in mind it seems! You can build it vanilla, or build it extreme, so you can have the kind of unit you want. I'm glad this all came together so well for you Lee. Looks awesome!

Thanks. My summer has been way too busy to actually get it up and running on my board but it all tests out. I bought a bunch of those redco square plugs that I learned about from you. Hopefully this fall I'll be able to build up all the cables I need to get it working. I may have to rebuild my pedalboard to make it fit but that will be fun. It's definitely the perfect loop switcher for my setup and I'm really glad I built it. You and Thomas nailed it.
