    Roboto, with a cavaet

    First of all, this is a really cool and unique pedal! I love all three DBA pedals I've built (please trace more @Robert!), and this one is no exception. Here's the catch; I used a 1P8T toggle switch instead of a 2P4T. It works, and sounds awesome. I haven't tested it extensively and won't be...

    War Scythe - incredibly noisy

    Hey all, just finished putting together a War Scythe build with the cleft mod. I used a 2N1306 for Q2 (the AC176) as that was the only NPN germanium I had (this could be the problem, but I can't compare). I originally tried the 2N5089s for Q4 and Q5 as per the mod, and that was noisy. Switched...

    Understanding the Hydra Switches - Schematic Analysis

    Found this schematic of the Hydra circuit in the forum, and I'm trying to understand how the switches work in tandem with the FV1. Pins 16, 17 and 18 (S0, S1 and S2 respectively) are connected to three of the switches, one each. The pinouts refer to these as related to program selection, so I'm...

    War Scythe Cleft Mod - Handful of questions

    I have a few questions before I keep going with this one, they're all relatively simple. 1. Looking at the build docs, it's D2 and D5 that are swapped out but then C16 is left blank (I assume unpopulated means no jumper either). C16 is in the first feedback loop; should C19 be left blank...

    Oddity Build

    This one was a request from a client (admittedly my only one), and while I was skeptical having never played one before, it delivers on a classic light overdrive sound. it can do a clean boost and a gritty drive for your amp or other dirt boxes. I didn't have time to look into mods, but this is...

    Taqueria Build

    Short version, I like this pedal and there's not a lot of bad sounds in there, but I think I need to stray from the path in terms of biasing and just use my ear. I LOVE the biasing pads, thank you @Robert!

    DEMO Circulator!

    Hey everyone, this is #38 overall and I think the 9th in April. I've been fighting an XC Phase* on and off, so I was excited to have a phaser I can rely on! this thing has some cool sounds and I really like that I can get almost an autowah effect with it. It was a fun build and I'm glad I waited...

    Captain Bit Build - Transformer Fixed!

    So this pedal is super fun and cool!!! I love dialing a fat saw bass noise, then running that into the Octaclave. Key note, primary side of the transformer points towards the top of the board!! I had to do surgery on a grape to get the transformer out, and it left a ton of damage. I also...

    Octaclave Octave Fuzz

    tldr; Good pedal. Primary side of the transformer goes towards the TOP of the PCB. So far I'm really enjoying this pedal; even more so once I flipped the transformer around! It was a pain in the ass but I managed to unsolder it and jimmy it back in. I used D9B diodes, I have some others I might...

    Specialist Reverb + Default FX Switch

    There's like two dozen builds before this I haven't posted, but this is a great one to start with, as it is my first commissioned build, my first FV1 build and my first "proper" mod (ie not just a different component value). I LOVE this pedal and will be building one for myself. I have a Walrus...

    Super Heterodyne - Divebomb sound with no input

    Hi all, just finished this about an hour ago after the delivery was delayed due to the big storm in the northeast. While I'm playing it sounds cool and I believe is working correctly, but if I don't play or even unplug the input, it'll make a kind of divebomb sound falling in pitch, like a...

    Combo Pedals - Do I just chain the output to the input of the second one?

    Hi all, I have a couple combo build ideas, but my first is pretty straightforward: op amp and transistors big muffs, with two footswitches and a toggle to flip the order. My intuition tells me I can just wire up the inputs and outputs to the order switch utility PCB and call it a day, but...

    Celsius Preamp - Whining noise with switch on High

    Hey everyone, I mentioned this in response to a build report but wanted to get some more in depth help here if possible. The preamp sounds like it should, but on higher settings with the switch set to High there's a "whine" that dominates the sound. I switched out 3 different each of charge...
