Probably the best finish I've gotten on a pedal so far. Drill guide didn't QUITE line up, but close enough I could make it work. Top plate is anodised aluminium I laser engraved, everything else was pretty standard with a hand picked MP20 (84hfe, 90ua of leakage). Is it worth the hype? Not...

R just means resistance - makes it clear that 100 is 100, and not 100k.

Howdy, I've just had my third order turn up from SOVCOM on eBay - first two orders were perfect (and 10/10 transistors I ordered were right in the middle of the gain ranges with minimal leakage), but this order got lost somewhere in the Ukrainian post system (which is understandable given...

I attempted to make a Woolly Mammoth 4-5x when I was much younger (15 or so years ago) and never got it to work. Last year I made a PCB for one and it worked perfectly the first time.

Sooo... I was poking around with my multimeter to check other voltage points while it was on and suddenly it started working. I've wiggles and moved every single component I was near and can't make it stop working. Maybe some sort of tiny short I couldn't see? No idea. With that being said, it...

Weirdly enough I have the exact same issues as this guy, just with wildly different voltages around the transistor - which leads me to believe there's definitely some fuckery around there. https://forum.pedalpcb.com/threads/isosceles-boost-issues-tiny-no-signal-when-engaged.5944/ He also notes...

All switches/knobs do something, but it just sounds incredibly misbiased - no sustain, super farty, etc. It does appear the tone controls are working, but it's really hard to hear with how little noise I get out of it. Confirmed all components are correct (couple of minor changes; pulldown is...

You can panelize with KiKit

Shouldn't be a problem - you should be able to set up an exclusion zone to remove it if you're really concerned though

Op-amps typically want to see a bipolar power supply - something like +/-9v (with reference to ground). Just using a 9v battery you only have a unipolar supply (+9v/0, or -9v/0 if you flip the battery), so by using a equal resistive divider you get +9/+4.5/0. If instead of the ground/zero...

Tell me about it :p It's cool for vibes, but absolutely isn't worth it either from a cost or time perspective.

Just cutting tracks? Easy. However the whole process is: cut tracks cut half through-holes cut positioning jig removing board, cutting rear tracks applying UV-cure solder mask to both sides removing solder mask from both faces cutting through-holes all the way through cutting board outline As...

There's barely an offboard connection there that doesn't look like it's got a short, and with that much damage to the PCB I would be shocked if you hadn't got multiple trace issues

NE5532 will easily drive most reverb tanks, and plenty of schematics out there for full send/return circuits with all controls included.

Create your two separate ground planes as nets (ie. I use GND and GNDD just to make life easy). Place a symbol called "Net Tie" on your schematic, and connect the ground to it on opposite sides. Attach a footprint to it - use any of the generic ones (just redesign it to suit once in PCB...
