I'm troubleshooting a couple of PT2399 circuits one is the sagan delay the other aleph null special sauce. The Sagan passes only clean signal. and all pt2399 are getting 5.78v. I know the 2399's are supposed to get 5v (the " I know" part is an idiot telling you HE knows something and he just...

Recently re-built an Emma ReeZaFratzitz again . Its been a few years . As with transistors and their varied variables does this apply to IC chips also. Cause I remember my first build being a screaming distortion but this sounds a bit .....less. Are there variations within an IC chips...

I've completed my build. I can get a mild flange turning the bias trimpot . Trying to set the clock trimmer I do have a DVM with frequency duty cycle setting. Going to the test point I get a reading but after maybe 5 seconds it goes to zero , thinking I moved the probe off tp.1 i check and get a...

After doing some random reading on this forum I came across a great idea( I think) "I appreciate that! I did pickup those 47u caps a while back from Mouser and just got a bunch of bucket and clock chips from Cabintech. I think I'm ready to go but I'll keep that in mind. It'd be cool to set up a...

The trimmers , 1 100nf cap and 1 unbelievably problematic .... 5pf cap. I have everthing but the 5 pf cap. What I do have is a couple of options 1 - I have ceramic caps marked 10 that read between 0.072nf to 0.0.052nf on the capacitor setting on my DMM 2 - I have 15pf...

I can't seem to find any 25k trimmers for this build ( so far). Can I get away with using a 30 k trim pot? It's the last part I need to complete this one> I wouldn't think there'd be a problem using a 30k since it's a higher rather than lower value. but, .....well that's why I'm here asking...

Is it ok to use tantalums where electrolytics would go, on this build specifically the 1 uf ones?

Finally got mine working. Is there a specific order to tune the jfets in?

what would cause the 78l05 give an out put of 7.5 volts ? I can't figure it out.

I do. 3 ring binders for all my printed pedal build docs. and spiral notebooks with my pedal chains and settings. I also have notebooks with my likes and dislikes about all my builds. and a few more notebooks on each pedals horoscopes. how else would I know whos gonna get a long with...

I have several Choruses. A Liquid Chorus (I forget who makes it) , a PSK Chorus , EQD Sea Machine , Seppuku Mind Warp, and a Boss CE-2 clone. I love just a taste of chorus a lot for my tones but haven't found THE perfect Chorus yet. What's your thoughts on the Chorus pedal?

After almost 3 years I finally got the correct transistors for my much anticipated Openhaus pedal Madbean's Orifice. Sadly it sounded about the same as with the other transistors I've tried. Saying this exact same thing on another forum someone mentioned that possibly the transistors are not...

I recently etched and stuffed the board. I had no TL022 and no TL062. Using my limited knowledge and the power of the internet I saw that lm358 and lm1458 are used in some LFO circuits . using the circuit below I subbed IC 1 & 2 with the 1458 and IC5 with LM358 and the board did'nt work. My...

I finally went back to my Slow gear build which did not work initially and I found 2 components that were the wrong value and replaced them. I now have it semi-working. Fiddling with the knobs and trimmer to get it dialed in with no luck As of now it does a half assed job. I have my guitar...

I got one of these recently. Problem is I don't know if any of the information is really relevant to me and pedal building. I was hoping someone could help me decipher the readings I get from the tester then trying to compare that info to the data sheets but I'm really just pissing in the wind...

I think I have the answer but asking anyways So my build calls for 2n1306 I have 2n1304 and they have a bit less gain than the ones called for (2n1306) My question is since the 2n1304 have a barely any overdrive and I think I can get genuine 2n1306 BUT if I could get 2n1308 would I get even more...

This time I used Madbeans layout. Its the furthest I’ve gotten on this monster. I am now signal tracing it and get signal up to and out the gain pot. I had a couple small bridges to fix and found that R7 is either 150 ohm or a 10M neither is correct should be 100k which I have not fixed yet...

Just a shout out to PedalPCB for another fine fun pedal with lots of knew sounds to experiment with The pedal? The Organ Donor. After finding faulty wiring on the 3PDT it fired right up. 2nd time soldering the FV-1 to a board and no problems. I just make sure I file my soldering tip...

Having a massive brain fart happening here. Some reason I can't figure this ultra simple wiring. I've omitted the battery snap and thats the only change. when powered up I get no LED's to light up. I think I know where I messed up by running the D.C. ground to the input jack ring lug kinda like...
