wow, that’s super informative. thanks for going over it in that much detail. maybe i’ll swap out s few of the caps i’ve got in some of these boards i’m preparing.

oh yeah? like across the board better?

thanks, i'll check it out!

i'm gearing up for one of these myself. can you share your reasons for using tantalum caps instead of electrolytics in most places?

i switched from adobe suite to affinity (didn't nab publisher just yet) about a year and a half ago, and i have to say i agree wholeheartedly with the above recommendation. as a long time professional user of photoshop and illustrator it has taken some getting used to, but my opposition to the...

heh. for proper mojo effect, i guess i was expecting something with cyrillic or klingon writing on it or something :alien:

the struggle is real. especially with these 1590G boxes. i bought a few thinking "these are great!, and not realizing they are much more shallow than the 1590A or B... i can't seem to do anything the easy way.

this is VERY cool. what did you use for C4, and C6? looks like the parts called for on the original BOM are gone from mouser

thanks a bunch! oh no, am i in trouble?

i have to say that even though i was having a high pitched frequency problem when i initially populated the board with all 2n304s for whatever reason the tone of the thing didn't really light my fire that much. after coming on here and asking for pointers i just tried some different things with...

this is my first pedalpcb project, and i hope to have many more to come! i dabbled in pedal building in my early college years, but that mostly only served to generate a small box full of partially functioning 3ms pedals that were far beyond what i should have been attempting. anyway, a lot has...

wow! easy enough. thanks!

looks great! what can you tell us about the paint job? i'm into it!

i see. i did expect it to be somewhat more noisy unboxed, but also didn't think the squeal would be coming from a lack of shielding, etc... i'll be ordering some of those alt transistors and see what i come up with.

i may have a couple 2n4401s, but not the others. when i tested the circuit i was using a test rig that i’m building, which is not mounted to an enclosure yet. however, i’m working on enclosures for both the tester and the derm today, so hopefully by tomorrow i’ll have a housing for both. would...

here is the component side as-is. i’ve pulled the transistors for the time being

hi, i commented on another thread, but it doesn't seem to be showing up on the "what's new", so maybe nobody has seen the question. hope this is not an anoying redundancy if you've scrolled past this question already. i've just tested my two sticks of derm board and the effect is quite nice...

actually, i do need some help here. i went through maybe 10-15 2n3904 units and still got the shriek/squeal which is very annoying. i don't have a way to test hfe that i know of right now. i ordered a component tester that should be here next week some time. is there another component that can...

glad to know i'm not the only one who is having this issue, although for me the squeal-ish thing only happens at the last little bit before maxing out. i'll try the changing out the transistors as recommended. god bless the search function here.

great tip re: the plastic shaft. i'll keep an eye out for aluminum shafts only. thanks!
