    SOLVED: Spirit Box - Unity Gain Issue

    The 470n caps I’m using are large but I’ve shaped the legs to fit the board. I’m still new to schematics so wondering if these can affect volume/unity gain.

    Spirit Box w/ Fuzzdog mods

    Stared a new thread. I was going to do that but wasn’t sure which was better … to start a new thread or add on where a similar issue was already being talked about.

    SOLVED: Spirit Box - Unity Gain Issue

    I built the spirit box Pcb and noticed a drastic volume drop when the pedal is on. In other words, I need more volume to achieve unity gain. I’ve been reading that the best approach is to increase the resistance value of R4. I started out with 10k. I tried 18k, 20k, 47k, and 68k. The higher I go...

    Question about Breadboard Wiring and Grounding

    I have this question about wiring up a breadboard. It was too long to type, so I put it in this YouTube video:

    FV-1 Questions

    I just have a few FV-1 questions. 1. Is it possible to feed a signal into two modes without needing 2 FV-1 chips on the board? (For example, can I send spring reverb into a shimmer and hear both at once?) 2. I’m noticing FV-1 chips cost much more than PT2399s. They are like $15-$20 each. Is...

    TL072 Question

    In a guitar pedal circuit that calls for a TL702, do you happen to know if they are interchangeable? And if so, does the sound get altered drastically or only slightly?

    TL072 Question

    Something I’m confused about with the TL072 is all the different versions. (TL072CP, TL072BCP, TL072ACP) What are the differences?

    Is WIMA just a brand name thing or do they sound better & last longer?

    PT-2399 Quality Question

    Looks like that deal I saw is no longer there. It was something like 20 pieces for $7 or $8. Must have sold out.

    Which is best for the Spirit box 100uF caps? 25V 6.3x11mm Or 16V 5x11mm

    PT-2399 Quality Question

    I’m about to order some PT-2399 chips and noticed that they cost about $0.35 on Amazon and about $2.40 each on StompBox. Are all PT-2399 created equal or are there quality differences between different price points? I imagine they sound exactly the same but may not last as long. (Similar to...

    Ceramic Capacitor Differences

    For ceramic capacitors, what are some of the differences between these two types and are they interchangeable? Differences in sound? Quality? (Not wondering about the pF or nF values, I realize the ones in the photos are different values. I’m building my cap stock and wondering which I should...

    Kliche Mini - Tone Knob

    I had posted a similar question back in April but didn’t get a response. I’ll try to rephrase it in case the issue was in my wording. I want to modify the Kliche Mini so that the tone knob adjusts a different frequency. (I’d like more of a high-frequency sparkle and less of a mid-high sound...

    Sandspur Fuzz - Volume Loss

    Ok, thanks. Just a follow-up. I’ve purchased new “solder lug” pots on stompbox. Hopefully I’ll have better luck with those.

    Sandspur Fuzz - Volume Loss

    What I’m trying to accomplish is bringing those internet controls to the outside. Explain to me why this is not a good idea. I know it has level, fuzz, and sundial on the outside. I’m assuming you are saying that the sundial is the bias where it’s min and max are controlled by the internal range...
