i used: - x2 TL082 in the Qx positions that service the LFO stages (& output stage) - x1 TL072 for the input stages. - x3 4558s for the LDR stages. i would only suggest that it’s necessary to use a low current device like TL082, TL022 for the LFO stages to minimize LFO noise.

lol ok

real circuit or or pretend simulation?

not sure if useful - but i still have my breadboard build (didn't notice any oscillation at maximum fuzz)

imagine paying money for software... i prefer the analog version, it's kinda hard to hear graphical waveforms

not a problem. I recommend you start by posting a thread in the troubleshooting department ➡️ https://forum.pedalpcb.com/forums/troubleshooting/post-thread dont forget to include photos of the whole build, including close shots of both sides of the board. ay cheers :coffee: depends... if im...

heck yes. this is good to hear, still yet to build my brownout have you tried boosting it with an SD-1?

https://sheepylove.com/products/dark-sheep the only reasonable choice is an MT-2

💯 yep - definitely been the culprit. 100n would have been shaving tonnes of treble off at the end.

looks ideal. are you following the sola sound schematic at the top or the vox schematic below it?

that's a fair point. i guess the point im trying to get across, is that your options for useful / viable transistors opens up a fair bit if you're willing to put the circuit on a breadboard and tweak it/dial it in (using non-stock / non-standard values) to suit the transistors that you can get...

a fuzz face is a fine choice. - forget gain values. it doesn't matter as much as people bang on about. - adequate leakage is most often a good and necessary requirement. forget this arbitrary 100uA cutoff thing. (heck i would even suggest 100uA as a minimum requirement) - you do not need to...

- show us the breadboard build - post your voltage readings (particularly Q1c & Q2c)

big bakelite knob looks great 👌🏻 how’s it compare to a regular ol silicon FF?

great name ^^ i imagine that this is what it would feel like to use this pedal

yep. it really is the most redundant bs toggle option. +1

that's some good thrusting

hell yeah. this is the way. i should probably do it this way too, but i’m deranged and insist on using virgin components for final builds

confirmed. i was sold fake OPA2134PAs (wasn't aware until a problem showed up later). emailed them about it. they conceded and gave me 'refund' credit.

i'll either make a post about it somewhere here, that i can then refer back to later, or ill just write some notes in a little booklet/pad. photographs of breadboard builds have also proven to be quite valuable to me during moments of 'wtf is going on here' / 'what did i do?' usually this is...
