Earthquaker Devices Tentacle

Had several requests for the Tentacle, but it's just more or less a Dan Armstrong Green Ringer clone. But I had the idea of making a Green Ringer layout with the bypass footswitch board-mounted so we'll just call this layout the Tentacle. Should fit easily in a 1590A. If you'd rather a fabricated PCB to build on, check out the Darkmantle on the store.

      Anything medium to high gain hFE should be fine. 2N5088, MPSA18, BC549C etc

    Thank you for the layout! I used it to create a double octave up with selectable Si/Ge clipping diodes in both circuits. Sounds beautiful. In this demo I played an acoustic Martin into a 65 Princeton Reverb: https://youtu.be/1euyGmRCjUA

    Hi, noob question, but there's a 47n capacitor in this schematic that is not in the layout. Is it better to omit it and just go ahead with the layout template?? http://guitar-fx-layouts.42897.x6.nabble.com/file/n34610/EQD_Tentacle_schem.png

    Thanks!

    Try BS170 (same position) or 2N5088 (inverted) in Q2. They sound amazing! Q1-Q3 2N3904.

      Personally, I prefer the 2N5088. But give it a try!

    Hi, it's the third time i try to build it, every time with a different pcb, checked everything, and it doesn't work, just no sound, build it with 2n5087, 2n3906, 2n5088, bc549c every possible combination, changed the 100nf next to q1 for a 47nf ad nothing, i don't know what i'm doing wrong, i even tried out one i found in stripboard, and nothing, and it's not my first build, i've built nearly 10 pedals here, all perfect, this pedal hates me :,v

      I dare say your transistors could die from static during soldering. Google this moment. I have faced this problem myself
