    My first tube amp build 5f2a

    I'm not great at describing tone, but sounds really nice to me. This is my first Fender-style amp. Although I've owned and built tons of pedals, I've only owned one tube amp before--it's Peavey Classic 30, and I've had it for almost 30 years now. So I don't have a lot of experience with...

    My first tube amp build 5f2a

    Just wrapped this up. I took my time building it, also researched a lot both before and during. It has some mods, but nothing to change the tone much, mostly for safety: Added a RC filter stage of 22uf + 250R before my B+. This was to reduce noise and it also drops the B+ voltage by about...

    A Blast from the Past - Custom Flanger

    Very cool. How come other Electric Mistress clones I see have way more ICs and parts? Are there more than one electric mistress circuits?

    Automatic Wire Strippers

    I saw those recommended elsewhere. And those are dead ringers for Harbor Freight, which is one of the reasons I bought the HF model. I'm guessing they're OEM from the same factory. It's possible the Weicon's have specced different blades or springs to change the performance, but I'd still be...

    Automatic Wire Strippers

    I did see these getting good reviews (as well as a couple of similar looking no-names) when I was shopping around. I figured the harbor freight would be equivalent to all these. And it works well with small wires?

    Automatic Wire Strippers

    Anyone have good recommendations for wire clippers strippers that are effective at 20-24 awg wire? (and that don't break the bank) For most, 22 or 24 awg seem to be the advertised limit, and from what I read they don't work well at the edge of their range. I just bought this inexpensive one...

    What are these diodes doing?

    thanks, I caught that before I saw your reply.

    What are these diodes doing?

    Both diodes go to Vcc. I would expect this to keep the voltages between Vcc +- Vf and clip signals above or below that range. On second look, one goes to -Vcc. So it'll keep the voltages between -Vcc-Vf and Vcc+Vf. It seems like that would have very little impact as the IC is also supplied...

    Current Tayda fees after new tariff?

    I wonder how much business Tayda (and other overseas sites that cater to niche hobbies) is losing over this? I hope they stay in business.

    125B General Tso's Compressor

    Yeah, I used a standard 4 knob for mine, and added a washer on the switch to account for the larger hole (but that was because Tayda was still selling pre-drilled for cheaper than custom drilled).

    Simple tone generator for audio probe

    Awesome, thanks everyone, I'll breadboard a few of these and see what works for me.

    Simple tone generator for audio probe

    When using an audio probe it'd be nice to generate a signal (usually I use a looper pedal, but it requires some extra steps). I see this SMD based circuit in the shop here https://www.pedalpcb.com/product/pcb668/, but I'm more inclined to throw it on a stripboard. Anyone have a simple...

    Duocast - Transistor?

    Perhaps your transistor isn't rated for above 9V? Which transistor did you use?

    looks great! can you share a tutorial video (or more than one) that you found helpful?

    Best brand of breadboard

    Busboard also makes great vero/stripboard. The tracking and the traces are nice and thick.

    new build: Duck Box

    yeah this one was underwhelming effect-wise (I assume that's what you're experiencing). I do find boosting the signal into it helps quite a bit, so try that.

    Current Tayda fees after new tariff?

    is any company actually giving rebates?

    Current Tayda fees after new tariff?

    I wonder if their low price shipping option weren't managing tariffs so they dropped it or something like that.

    PedalPCB source germanium transistors?

    According to Aion's build doc for the Broadcast: "Others including the Dual Broadcast use the NTE 2N404A, a new-production germanium that is anywhere from 50 to 250 hFE. The 2N404A taken from a Broadcast in this video measured at 216 hFE with 125µA leakage." So I guess it sounds "relatively...
