Great demo, Michael! Nice build too. Question: can you measure the drain voltages on Q1 & Q2, please? I'm curious how the JFETs are...

Ok, here's a demo of the Sugarbag for @Harry Klippton :ROFLMAO: . I was originally going to b use a couple of different guitars...

If you don't select Q3 / Q4 properly, you run the risk of :poop: tone.

It's a slang term that depending on context can mean fake, counterfeit, broken or fucked-up.

For a diff pair to work, the Vbes need to be matched. In the case of JFETs, Vp needs to be matched and we know what a PITA that would...

Chuck, what do the following changes do to the circuit? “After playing with it a bit, I bumped C7 up to 1nF, C11 up to 15nF and changed...

I was thinking the same. It is a push pull simulation. So I googled push pull with Jfets and BJT. My guess: JFet asks even more biasing...

So why the BJT transistors for the phase inverter? Why didn't the designer stick with JFETs throughout? Is there a tonal advantage here?

It's worthwhile to read the backstory of this pedal on the Aclam website. I breadboarded this baby in accordance with the Beatle Juice...

Yeah, I don't know what MXR engineers were thinking when they put that LDO in. IMHO it's not needed. Most everyone has a regulated...

Mid control sweep looks like a genuine improvement I've been putting volume controls before tone stacks lately, it's good to see I'm...

It is very compressed due to the hard clippers. One thing I tried is putting a 100Ω resistor in series with the clipping diodes. The...

Ah thanks for that. Had to google Vbe and take a better look at the schematic. So this pedal is a high headroom stage into a low...

Yes. The PENTODES knob controls how hard the output stage is driven. That's correct. Raising the power supply voltage does not...

No, but I can tell you analytically what to expect. Raising the rail voltage can improve the headroom or gain of the JFET stages (Q1 &...
