    Got bored built some stuff. Poison Apple/Soul Drive/Troglodyte

    Nope, that is the “blue vein” from stompboxparts. Way too cold for rattle can jobs since I do mine outside. Edit: Aqua Vein

    Missing Build Docs / Schematics

    Any chance on getting the microblend schematic? Want an active blend but not set up for SMD so would like to Vero it

    Transistor Socketing and heat shrink tube

    Sockets can become unreliable. With multiple transistor switch outs the sockets can become loose and you run the risk of the transistor falling out of the socket down the road. As far as heat shrink I have never applied heat to the shrink wrap, I have some really small stuff and it’s really just...

    Poison apple. help me think through what I am seeing

    Thanks for the info. Once I moved my regulator off board I am getting the correct voltages where expected. The 5457 has clean signal going through it. This is going to be a really dumb question, but I am second guessing myself after staring at the schematic for far too long, but does the audio...

    Poison apple. help me think through what I am seeing

    All settings. I did a brief audio probe and it seems like it’s being injected at R5 BUT I actually don’t hear it coming out of the LM13700. I thought maybe me releasing the magic smoke on C100 (which was rectified) might have caused some AC leakage, but strapping a cap across the power terminals...

    Poison apple. help me think through what I am seeing

    Thanks for taking a peak at my problem child. So I have tried 2 different sets of lm358 as well as the TL072 which came from Mouser so would trust to be reliable. All with the same issue. I somehow must have borked the regulator section of the board. Off boarding the regulator solved the...

    Poison apple. help me think through what I am seeing

    Well, the popping/thumping is resolved but I am still getting light distortion on the E string and some of the higher frets of the A. Sounds a bit like fret buzz, but it happens with multiple guitars (Humbucker and single coil) and is gone when I turn the pedal off. Going to audio probe some...

    Poison apple. help me think through what I am seeing

    The regulator I am using is the one pictured so I’m going with there may be a short. In desperation I have off boarded the regulator on a vero and fed it into the left pad of the regulator and every thing seems to be behaving. It’s what I get for taking a build break.

    Poison apple. help me think through what I am seeing

    So my Poison Apple “works”, but I am getting serious popping/thumping at the envelope opening and even a little distortion on lower strings/frets. I have been pouring over this thing doing all the troubleshooting basics and the thing I keep coming back to is that my 5v keeps disappearing. So...

    Got bored built some stuff. Poison Apple/Soul Drive/Troglodyte

    For reasons, I’ve started building things again. Maybe just needed a little retail dopamine hit from getting packages in the mail and building. Trying to stay within the limits of parts on hand to mitigate having to order a bunch from stateside suppliers. First up is a Poison Apple auto wah...

    What's on the workbench?

    Just putting this out there…..Zshmeks Ringtone…eh….eh? But also, are the other synchro boards going to be restocked?

    Vibrobot distortion

    Thanks for the heads up. The build was banished to the pedal oubliette and to be honest will probably stay there. Not going to spend $$$ (relatively speaking) chasing obsolete chips to find one that gains me no greater functionality than I can get from a basic TR-2.

    Missing Build Docs / Schematics

    Is there a schem for the microblend and would this work for blending pickups in a jazz bass?

    Pickup winders? Raise your hands

    Questions about send return loops

    If nothing else you could maybe look at the schematic of the Tatiana and see how it separates the loop OR figure out how to break the feedback part of the loop to get the functionality you are looking for

    Questions about send return loops

    Look at the DEFX Tatiana. It has an overall bypass but the loop is activated by a momentary switch so so long as you have the pedal on, but don’t press the momentary, the pedal in the loop remains “in the chain.
