    questions about a broken dual pot on a bass.

    Hello, Something heavy fell on my bass, and the top of the Bright/Volume dual potentiometer is broken. The top is controling the volume. I'm trying to fix it, but it's soldered on a small pcb and it looks like im not going to be able to desolder and replace it. Im thinking about leaving it...

    How does impedence work in long signal chains ?

    Hello, I recently build an analog delay and noticed some issue in a long signal chain with 10 or 15 various effects, including buffered bypass circuits from Boss or MXR. Some circuits are decreasing the delay's repeats and response, even in bypass, depending on where the delay is connected in...

    Star Chamber MXR M118 delay clone : possible issues with other buffered circuits in the signal chain.

    I noticed that my Star Chamber build has a weaker delay with less amplitude and repeats when i engage some circuits before it. For example a looper/mixer/blender circuit (Pro-cessor from TH Custom Effects), or even a Boss GE-7. I also have this drop with the delay response after a little EQ...

    Byzantium (BF-2), Ocelot (OC-2) and Lectric Fx's Star Chamber (MXR M-118).

    I thought i had already too much circuits, i thought i decided that i wouldn't build more anytime soon. ...Then i saw that musikding had recently started selling Byzantium kits. I always wanted to build this one. I also realized that there is a few new delays available, i hesitated between...

    SOLVED Byzantium calibration questions

    Hello, I am calibrating the byzantium and i m not sure how to set the Clock. The other 2 trimmers are easy to figure out, but Clock calibration is a bit more tricky for me. Madbean has a similar project, so i checked the instructions to calibrate my build...

    WarScythe : volume loss and sub question.

    Hello, My last build is an Hoof Reaper clone made with a musikding kit. https://docs.pedalpcb.com/project/WarScythe.pdf Everything sounds fine as far as i can tell, all controls are working. I only noticed one obvious issue : If i just use the Tonebender and if i activate the octave, there...

    War Scythe : settings suggestions and circuit explanations.

    Hello ! My last build is PPCB War Scythe. It sounds promising but i'm not sure i understand what is happening in there. There are 3 circuits: Ungula, Squidward and Scythe. I know nothing about the original circuits, except they're from EQD, there's a muff variant (hybrid ?) a tonebender...

    Extra pair of MPSA13 in War Scythe kit : Why ?

    Hello, I just built the War Scythe kit from musikding. Everything works fine, as far as i can tell. https://docs.pedalpcb.com/project/WarScythe.pdf There are two MPSA13 transistors in the kit, and i m not sure why. I guess it's supposed to be used as an alternative for some other transistors...

    Tube question : TAD RT372 vs RT272

    Hello, I need a new spare set of tubes for my Blues Junior 3 : 3x ECC82 and 2x EL84 The original tubes are getting fried one by one after 9 or 10 years of service. EL84 were GT Groove Tubes, the ECC82 are still fine so far, but i guess after 10 years they will also fry sometime soon. Looking...

    Bass Dude, Omnilooper, F-24 Multi-FX

    Here are a few interesting builds. Nothing went wrong for once, they aren't the easiest builds but with good instructions and a little experience, everything went smoothly. Let's start with the Omnilooper from Schalltechnik_04 : https://schalltechnik04.de/en/instructions/omnilooper Best...

    [SOLVED] JamMan Xt Solo power supply replacement question

    Hello, The XT Solo Loop Station power supply just died. it was old, i might as well buy a new one. The problem is that the DC power input jack on the JamMan is slightly smaller than the usual ones. I can't use my other power supplies, their connectors are slightly too big and won't fit. This...

    How to load effects into EEPROM ?

    Hello, I am building DeadAstronaut's F-24 Multi-fx project. It's almost done, and i suspect the two EEPROM sent with the kit are empty. But the project includes a 6 pin header to access the EEPROMs...

    SOLVED Aion Xenotron : Manual control issue

    Hello, this is my second troubleshooting post on this circuit : i thought it was ok, but it's not compared to other builds. https://aionfx.com/app/files/docs/xenotron_documentation.pdf The obvious issue is that on my build it is much harder to dial some good modulation settings, compared to...

    Quick question about soldering residue cleaner

    Hello, I've been using some residue cleaner recently, and i notice that pads are much harder to reflow after cleaning the pcb. When applying heat to reflow and improve some soldering joint, i can see bubbles and strange things going on on the pad, it feels like i should remove the cleaned...

    Phase II : Low Pass, Vibrato and 2 stages mods

    I built a few phasers, the Phase II is probably my favorite, i really like how the sweep sounds. However, i built an other one sometimes ago, a Small Stone clone with all the popular mods, called the Redshift from Aion. The mods are allowing some interesting sounds, and i often regret that...

    DEMO Aion's Redshift and Spectron (EHX Small Stone and Lovetone Meatball)

    I built these effects sometime ago, in 2021. Hopefully, they could be some interesting examples about what is possible to do when a pedal builder has "no artwork skills". The idea for the "art design" came to me while i was shopping at the local grocery store. I saw two big packs of rice, one...

    Soldat Distortion (Providence SDT-2), GCI N.E.W HM-2, Frequency Interchange Filter

    I built the SDT-2 because i like some SDT-1 variant very much, so i wanted to try it. It's a great distortion able to get heavy on the low frequencies, just as i like them. It's quite different from the GCI Bass Brutalist which is based on the SDT-1. The gain texture feels a bit more precise...

    Black Eye Distortion and Proposition Distortion (Rockman Ultimatum Distortion Generator)

    I decided to build the Black Eye upon recommandation from @jhaneyzz. All my thanks for this kind suggestion ! The fact that some Sushi Box effects are available at musikding, allowed me to build this project. This circuit sounds amazing, it's impressive and very inspiring, it will be put to...

    Neurotron (Lovetone Ring Stinger) and Xenotron (Lovetone ? Flanger)

    After a few years building stompboxes, i felt confident about these big builds, and i was very curious about these Lovetone circuits. I built the Spectron before (Meatball) and it is such a great circuit that i thought that everything coming from Lovetone must be amazing. I have to admit that...

    SOLVED Neurotron (Ring Stinger) sawtooth waveshape : low volume, no modulation.

    Hello, I built the Neurotron recently, from a musikding's kit. https://aionfx.com/app/files/docs/neurotron_documentation.pdf Based on what i could listen in the utube demos, it sounds like everything is working on my build (VCO, LFO, etc) except the sawtooth waveshape. According to...
