DIY Phaser Circuit With Voltage Control 

Haha, spooky!! Thanks for watching!

Same here! I'm working on a modified Compact Phasing 'A' design with additional controls & (hopefuly) shrunk down a bit. It's partly breadboarded right now, working on the LFO design at the moment. What is your basis of design? # of stages?

I'm not sure what everyone else's inspiration was, but I first started to take a look at this a couple years ago when I first found the J. Haible PCB/schematic & then got really motivated once I watched the Hainbach CP-A video last year.

@@damantis79 do you have a link to the schematic?

There's plenty on the way! :)

Really glad i could help! Definitely will do a full videos on JFETs & Voltage control as there's lots of stuff you can do with them :)

​@@TheAudioPhool I work with electronics in the context of sound - and everything else, or so it seems. And, it's feeling a lot lately like new or recent EE grads can't - or won't - try anything that's not FPGA based; uses a microcomputer or ASIC custom tailored for whatever they're tring to build out. I use OpAmps for signal processing because they're generally cheap: lots of LM358s and LM1324s; TL082s and what not. I love the sound of a multi-stage diode ladder. I don't care much for 555 based sequencers because I've yet to hear one that doesn't click and pop incessantly. A good decade counter, particularly one that'll reset at 5. VCRs built from a single JFET and not much more, now that's impressive. I've gotten some sweet results out of an NPN and a PNP 'long tailed pair" when the BJTs are complimentary and biased properly, too. Nice video; really like that you took the time to set up some simulations with Falstad's simulator; pix are worth a thousand words. Hope to see more from you and maybe exchange some iideas; maybe chat some. Thanks.

Thanks for watching!! :)

Thanks for watching :)

Glad I could help! :) I'm open to requests I just can't say when I'll be able to fill them!!

@@TheAudioPhool Hopefully it's not overly complicated, but I've been curious on how to make a smoothed random LFO. The S&H style isn't applicable in most cases, but a smoothed random would be amazing. While I think about it, maybe a video on random voltage on a button press would be cool. I really can't express how big this phaser circuit is for me. I make bass heavy guitar music, with four pedals output into a mixer.

@@tziirkq Both great ideas! It's on my list! :)

yes!

With Op-Amps, anything is possible!!

@@TheAudioPhool is it possible build a triangle wave where both the rising and falling edges can be adjusted (I.e. from sawtooth to reverse sawtooth)?

@@phyphedelic3214 tinyurl.com/y9fxk3x7 Just threw this together! As chance would have it a version of this circuit is going to be in my next video so a detailed explanation will come there, although i don't know if i'll add the saw adjust, it's essentially a triangle wave generator with the ability to turn it into a saw :) If you need mroe help, join my patreon where i take suggestions and help my patrons design circuits, and you'll also get early access to new videos! Thanks so much for watching :)

@@TheAudioPhool that is waaay easier than the method I’ve been failing @. I’ve been trying to do it following this method ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ibnz5UjQ4u0.html ) to no evail for ever. Guess you can do anything wit an op-amp😲. Thanks for the knowledge! I’ve gonna need some of your patreon support for another issue I’m having involving linear-exponential conversion. Being that it’s my first fully-functional VCO, I’m sure there will be many more questions to follow. Looking forward to working with you.

@@phyphedelic3214 Glad i could help :) Next few videos will be on VCO's, voltage control & CV so stay tuned!

Unfortunately not :(

You could try a P-channel MOSFET if you have some of those kicking about. The channel resistance will probably be much lower but it should still do some modulation

@@TheAudioPhool ok I will probably buy the components in the schematic then since I dont have any mosfets at all. Looking forward to if you do a video on voltage control cus I have no idea how to implement that kind of stuff on my own

@@LabSkaterPussies Videos on voltage control are incoming :) Got a few videos on oscillators coming up next where we will go over a few different types of voltage control

Dual supply

Yes any P-channel JFET will work. That's just what had on hand!

Cool!
