There you go: Vp (V) Idss (mA) 2.91 6.6 2.32 4.3 1.64 2.1 2.75 5.9 1.82 2.8 2.94 6.7 2.55 5.4 1.82 2.6 2.70 5.9 3.01 7.0 Can you share where you plan to use them? I have quite a few of them that I'd be interested to use

I'm using the rog tester with 100 ohm and 10meg resistors. My multimeter claims to have a 40MOhm input impedance. According to the 2n3819 datasheet, Idss can go up to 20mA

I was counting on you to have a solution! Both can be easily done, which one do you recommend?

I can do it, give me a couple hours! Not sure how reliable the Idss readings will be, because it can be too high for the jfet matcher (if I remember correctly)

This one looks amazing! Great job!

Thanks for the reply! I was already expecting you'd suggest I should breadboard it, and it's always valuable advice. I can see why you think that a toggle fits this one better

Hey Chuck, Do you think Turbo works better as a toggle or could it work as footswitch? I'm excited to build this one, sounds amazing based on Temol's demo

I might be completely wrong here, but a little simulation on LTspice suggests the noise control kind of controls how good of an octave you can get (versus a very f*cked up fuzz). It is changing the bias on both npn transistors. If you have matched transistors, you might get the best octave with...

I love everything about this! Wow!

Btw, @Robert, I love that you're now including jfet measurements. It's so helpful when looking for a possible substitute

Fun fact @temol and @DAJE : the 2n5457 spec'd in the build document for the Figment (migfet) are as out of spec as the ones DAJE has. They actually look like a very good match

The cutoff frequency is 4.8Khz approximately. The way I hear it, it's removing some of the harshness. In his Viceroy, Chuck has replaced the standard LPF with a variable presence control

In RunoffGroove designs (which I believe were the inspiration for this one) they usually use a second order lpf at the output to simulate (broadly speaking) the frequency response of a speaker. It's very common in jfet amps-in-a-box (right now I can think of wampler, eqd and rog designs that use...

Nice! Thanks for taking the time to answer!

Nice one, as always, Chuck! I have a couple of questions, if you don't mind: 1) Resistance values in the tone stack are smaller than we typically see in tube and jfet design, is it because of the lower impedance of mosfets? 2) other than 1) (assuming my reasoning is right) is there a reason for...

DeadendFx has a board for the Crystal Dagger. It's the Shard: https://drive.google.com/file/d/1ocYb4a0HaWZYs3LlNG0tKL1VbXGSi3le/view

Will do, thanks! There's one from the late Blackout Effectors, called Sibling Phaser. I think it's the same phaser circuit (or at least super similar) found in the Blackout Effectors Crystal Dagger

Thanks for the answer! I have had a lot of fun with a 3-stage phaser (3 stages for me is the right amount of effect) based on the phase 45 topology, if I decided to add some feedback would I need the cap?

The phase 90 is the reason I fell in love with guitar pedals! Why does the feedback go back to the 2nd all-pass stage and not the 1st one?
