do you mean collector or emitter? apologies, the references get a bit confusing when the transistor is flipped. for context, i’ve currently got your schematic breadboarded with some MP11A NPN Ge. with the collectors hooked up to resistors (390R) to ground, im seeing about 0.03V at Q2C and Q3C...

cheers guys, it’s not too bad making one when you can just use the metal lid as a template. i didn’t get it perfect, little bit wonky but im just glad the holes lined up

ayy thanks! 🤟🏻

i’m sure anyone that’s had a browse of the range at effectslayouts has seen this nifty little board. i only bought it cos i thought it looked cool, and it is cool, but i was never really sure if or when i was going to build it. but recently i’ve been enjoying building with 1590B, and getting...

hell yeah brutha 💪 built one of these last year, on vero. will go full on tight metal if you try boosting it with an 808/SD-1. i was also a little bit shocked at how much gain is available. which diodes did you sub for the Ge? (i also used 4148s in place of 51E) only really noticed a...

if you're willing to try building with something different... https://tagboardeffects.blogspot.com/2013/04/1-knob-fuzz-bonanza.html https://tagboardeffects.blogspot.com/2013/01/electro-harmonix-lpb1-with-trimmer.html

yeah i saw that one, was kinda shocked to see someone had actually used my layout. probably wouldn’t be that hard for someone (smarter than me) to adjust that schematic for a pedal application.

here’s one i did schematic taken from this project: https://paulinthelab.blogspot.com/2012/06/brian-may-deacy-amplifier-stripboard.html?m=1

🚨 zombie alert 🚨 inspired by the thread, https://forum.pedalpcb.com/threads/do-you-ever-rebuild-your-pedals.27329/ ive decided to post an update. anyway, tonight on this pedal got a tonne of use on my board since it was built, it did a heap of my band’s first shows for a year or so, until...

thank you ^_^ i just use a piece of card and make a little tray to fit the board (to shield from potential shorts) this one was from an instant miso soup box - shiitake mushroom flavour

a few weeks ago i breadboarded the V5 big muff and i was immediately keen to build one. ...and like many others, big smashing pumpkins influence, siamese dream being an inspirational masterpiece - this has been on my list for ages. it’s got a unique crunchy crispyness that the others don’t...

ehx bender royale

it’s the ‘super tube screamer’. basically it’s an 808 with a mid frequency boost opamp gain stage in front of the clipping stage. mid freq is adjustable, but the gain of the mid freq boost is fixed. aionfx has ‘current’ and legacy versions of it (‘cirrus’) i prefer the legacy board style, so i...

i've built all of them. OD-1, SD-1, TS808, OD808, while they're all kinda the same, yes there are subtle differences that matter. stock OD-1 is thinner, tamer, and smoother than SD-1. it's probably the most boring of the lot. OD-1 imo is closer in sound to 808 than SD-1. OD808 and TS808 are...

check the link i posted above. 50v skinny wimas.

or the dreaded yellow boogers https://www.taydaelectronics.com/1uf-50v-multilayer-ceramic-capacitor.html can vouch for this ebay seller: https://ebay.us/m/BM6qLv (i haven't bought these exact caps, but i've bought other obscure components from this seller before)

so far my big muff journey has been rewarding, so i thought i’d build another variant, but i also just wanted an excuse to do something cool with my minty green 100n caps on a vero build. for the benefit of less noise, i probably should have done it in a 125B instead of 1590B, but it's hard to...

nope. there are no dangerous voltages inside this amp (it's all ICs, no tubes) (except for at the power switch & power transformer, but they won't be a risk while the amp is not plugged in) just a good ol +15V/-15V supply...

take the advice given in this thread - that would be the first required technical learning.
