So you got this freind who put a Lo Baller together and barely had any effect , upon examination it was found a mylar cap was used in place of a tantalum same value wrong type That would be c3 470nf . Would this be the reason why there is no effect? Can an electrolytic be used in place of a...

Is it possible to swap out a tc for an lt 1044? whats the difference between the two? I built a caline englishman and the squeel is really bad I took a stripboard layout and got rid of the jumpers and moved a component This pedal sounds great from what I hear between the squeals. I've read a...

I'm building this . Yerasov 7000 can anyone tell me how changing (subbing) the (3) 47pf caps with 39pf or 56 pf I have also but how drastic of a change would that likely make . I may just socket them and find out myself but I thought it'd be wise to ask and as I started typing thought of the...

Has anybody recently purchased any legit lm308n chips? If so from where ? I want a few not just for the rat but a couple other builds I'd like to try. Took 2 gambles on it so far First Ali express ( I knew it was a crap shoot gamble from the start) and 1 from good ol Flea bay also a no go...

I didn't know where to post this so........... Just came across this place Talon Electronics . I have not heard any talk of it but they have a Huge Huge inventory BUT like only 2 of this item 1 of that sometimes more and prices seemed reasonable . Looks like a lot of hard to find goodies and...

Pedal is stuffed, pots and jacks wired up, everything but the bypass switch I did this layout https://dirtboxlayouts.blogspot.com/2025/07/solar-guitars-chug-lite.html?sc=1753678096700#c841080721134874214 from this schematic https://forum.pedalpcb.com/attachments/1000007278-gif.99100/ On...

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...
