    My second Muzzle is worse than the first?

    Hi Elijah, I just finished a Musikding kit Muzzle as well. It seems to work fine. Wired up the KEY passthrough as per build doc, but it was really noisy. I think because my power supply is isolated. So I connected the sleeves of the KEYs (slanted corners) together with a cable, which sorted...

    Thermionic Deluxe: doubt about clipping diodes lighting up

    Just saw your other question. Yes, when I switch to high gain channel and increase gain of low gain channel far enough, then also the low gain channel LEDs L3B and L4B start flickering a bit.

    Thermionic Deluxe: doubt about clipping diodes lighting up

    Sorry, I don't think I answered your question correctly. Yes, the gain control of the inactive channel has an effect on those LEDs lighting up. When gain is increased they flicker brighter, when decreased they flicker less bright. And if decreased far enough they stop flickering altogether.

    Thermionic Deluxe: doubt about clipping diodes lighting up

    Hi there, yes indeed, when I turn down the gain of the high gain channel and strum while in low gain channel, then the high gain channel LEDs L3A and L4A stay off.

    Thermionic Deluxe: doubt about clipping diodes lighting up

    True. They just light up when I strum, like written in first post.

    Thermionic Deluxe: doubt about clipping diodes lighting up

    Hi Harry, It does sound OK. I just found it a bit strange and thought lots of people already built it so maybe this doubt is easy to confirm or refute. Kind regards, Seb

    Thermionic Deluxe: doubt about clipping diodes lighting up

    Hi all! I finished a Thermionic Deluxe a few days ago and I have one doubt. Build Doc When I'm in the "low gain" channel (channel LED off) and strum some chord, not only the LEDs L3B and L4B light up, but to a lesser extend also L3A and L4A. Is this normal?

    Another day, another question! Recommended silicon transistor for a Range Finder build?

    Also wanted to say what spi said :) I like the Dragons Breath with the 2N2222A. Ranger Finder build doc says "Q1 is typical Germanium PNP spec’d for Rangemaster type circuit". So I'm just wondering if you can just swap out Germanium with a Silicon and call it a day without having the circuit...

    Soldering techniques

    Hi all, I had a little bit of a "revelation" when I was doing the Thumb Sucker. I was reading the Valve Wizard documentation (Link to PDF) and it said this: "Best soldering practice is to tack solder the component in place so it does not fall out, then snip off the excess leads. Then re-solder...

    SOLVED Another Squealing/Oscillating Boogie Monster

    No problem debrad, I have the JFETs in sockets so it's not a big deal. By the way, I just tried the SMD JFETs again with ROG settings. When I put a buffer in front of it the squealing stops immediately. I tried it with my tuner, a TC Polytune 3, which has a buffer built in. Putting a buffer up...

    SOLVED Another Squealing/Oscillating Boogie Monster

    Thanks for the video debrad! I have some spare SMD J201s lying around so I tested with the through-hole J201s that came with the Musikding Boogie Monster kit and the SMD ones. I think I may have been able to recreate the noise from your video, you be the judge. The attached recordings are all...

    SOLVED Another Squealing/Oscillating Boogie Monster

    Hi debrad, Could you upload a short sound sample with all knobs at 100%? I got a Boogie Monster, too, and find it strangely quiet. When I have all knobs at 100% I get what I would call a bit of feedback. But not sure if you're having just the same or if it's completely something else.

    Boogie Monster: picking the J201s

    Hi all, It worked out fine. I went with the through-hole J201 from the kit and put highest Vp to lowest (0.8 to 0.6) from Q1 to Q5. And then I set the drains to a bit over 6V at Q1 till Q4 as per ROG calculator. It sounds amazing. Never played anything with this much gain in my life. Always...

    Quality of guitarpcbmania pcbs?

    Hi all, I just boxed up a Vandal From Hell from them recently and I love it, it's brutal (once you boost its input a bit). Small nitpick, you need to bend one resistor a tiny bit to have enough space for the 220u cap next to it. The pedal was a tight fit into the 125b, but now I'm happy that...

    Boogie Monster: picking the J201s

    Oh forgot to mention something. Today the Boogie Monster kit arrived. And to my surprise it didn't contain the SMD J201s but instead Musikding put TO-92 J201s with an "F" marking on them and also a string saying "BAI7", or maybe "BAT7" or "BA17". And they measure at a bit higher Vp than the SMD...

    Boogie Monster: picking the J201s

    Hi all! Thanks very much for all of your replies! I didn't expect that many! I'll take your suggestions to heart and not worry so much about the JFETs in the Boogie Monster. I checked and found some sockets that I can use in my tool box, so I'll use them here for the transistors so I can swap...

    Boogie Monster: picking the J201s

    Hi all! I'm gonna get started on the Boogie Monster soon, tomorrow I suppose. I have a cheap transistor tester that shows Vg(off) and Idss and about 20 J201s (SMDs on adapters). So far I measured 10 and they have Idss from 1.1 to 1.4mA and Vg from 553 to 799mV. I read a post somewhere here on...

    SOLVED Closed Circuit C106 optional or not?

    Thank you for the information Bricksnbeatles, much appreciated. Will do it like you said. Kind regards, Seb

    SOLVED Closed Circuit C106 optional or not?

    Hi all, I'm building the PedalPCB Closed Circuit at the moment. I was about to solder the caps when I realized that I'm apparently one 100nF (=0.1uF) short. The Musikding kit contains four 100nF caps. It looks to me like a fifth 100nf was not sent because the BOM contained in the PedalPCB build...

    Thumb Sucker

    Hi all, I boxed up a Thumb Sucker yesterday. Easy build, didn't take too long, no problems. It's low noise. The bright switch difference is subtle, but when I turn it off I miss it immediately :) All knobs work. With the release knob it is a bit hard to tell. But I found that when it's CCW and...
