Hmmm, a voltage regulator for fuzz face bias? Now that's an interesting idea! I wonder if it's been done before?

Thanks for the tip. maybe it would be interesting putting an emitter-follower buffer on the front end the pedal to make it more consistent. I read somewhere that the low output impedance of a guitar and the low input impedance of something like this or a fuzz face means that your guitar is kind...

Thank you! I'm currently doing an electronic engineering course in college and I'm trying to combine all the stuff I'm learning theory wise with the practical knowledge I have from messing with pedals and other electronics. Of course, a modern bachelor of electronics engineering isn't that...

Thanks for the quick response. I totally missed the notification on this thread which is why I'm only responding now. I'm planning on drawing up a schematic based on the 2nd schematic, with PNP transistors instead of NPN, as good, high gain NPN Ge transistors are hard to find. Have you figured...

Those use resisitors to adjust the bias. Definitely different to supplying 6V á la a dead battery. Again, how different is it? I don't have the knowledge to make a definitive statement on this. A "sag" control actually is fairly different to supplying a constant voltage! Traditional "sag"...

Voltage dividers create a 'virtual ground' which are generally fine for say providing bias voltage to an opamp/transistor but are not ideal for power rails. They aren't as stable as a regulator. How much would this effect a guitar pedal? I don't know enough to say. But I never have seen a...

Thank you. I was thinking I would have to load it alright. The LED is a clever idea alright, though I don't reaaaally feel like fiddling with resistors to get brightness to match. Although it is just a simple equation and that barely even matters with bicolour ones so I might just do that. A 1K...

Hello! I am building a Devi Ever Ruby on stripboard and I want to be able to change from standard 9V input to 6V via a 78L06 with the flick of switch. It should be pretty simple, just have the power strip attached to a switch and flick between the 9V coming from the filter caps and 6V from the...

Hey, I'm about to get my hands on some hfe appropriate NOS transistors for this fuzz, what are people's experiences with biasing this thing?

Thank you. It does look like that I will have to get a 100k expression pedal to get the controls to work properly. I was just curious if I could use some parallel trickery to get most of the way there with a, say, 10k pedal.

Hello! Just wondering if It would be possible to add an expression pedal to control a 100k potentiometer to my build of the Hyperion 2, for the oscillation control, in a way that allows the full range of the pot to be smoothly expressed. I know how to wire a switching jack to a potentiometer...

Okay those are some very convincing results. Damn.

Inkscape for me is incredibly frustrating. Any time I want to draw something relative to a line with any degree precision, I end up having to create rectangles for rectangles for rectangles to use as guide and hope that it's not at too strange angles that one of the snapping tools won't decide...

This makes a lot more sense to me, a common graphic design noob, now. Thanks for breaking it down like that! Thank you, I will check that article out!

I've been trying to mix multiple fonts together on my pedal graphics for a while now (usually two, never more than three) just to break the visuals up and clearly distinguish between controls and the pedal name, and I've got to say, it's pretty hard getting multiple fonts working together! I...

It either looks like I could crack it open and get a packed lunch out of it or find a bomb. Okay now I want a lunchbox that's in the aesthetic of an old 5 knob ehx pedal.

Something about how that pedal looks really appeals to me for some reason. The guts look really tidy too, good job!

Been trying to find an answer to this one on google, but honestly, I can't find any good resources. Basically, I just want to know how much current is typically passing through clipping diodes either during soft clipping or hard clipping of a pedal, in order to figure out the Vf of a diode at...

Hello! I'm repairing a boss DD-3 whose internal wires are breaking off - they're all 26 gauge and have old, poor quality solder joints, so it's kind of like a game of whack a mole, where I repair one, another starts fraying and going bad as I have the pcb in a position I can work on it, putting...

Thank you, I will try that.
