Thanks, guys! Yeah, the crackle on the grit control is because the signal goes to ground instead of Vref and there is not output cap from opamp stage. Fixing either of those two would eliminate that issue.

Hi all, this project was one that I wanted to do for a while. It's been pretty fun digging into how oil can delays work and sound. Don't Tell Ray has a front end that can get gritty and dirty, a sinusoidal LFO, modulation speeds that match the hardware, and a tone control that allows the delays to s...

After we decided to modernise the Chorus on the Rockman X100 by using modern parts like MN3207 BBD and CD4046 PLL, and decided to add new controls like LFO speed, Chorus depth and Chorus delay time (while making sure there is a setting that replicates the Rockman) We took an existing topology of LF...

Once I resolve the LFO to give me the shape that I want, I've got a through zero flanger design using the 56028 otherwise ready to rock. Technically it's complete, but the LFO shape is a little more asymmetric than I want. I just need to sit down and bang it out.

Glad you guys like it. I have done an updated version of the Stalker with modified LFO control so that you can get even weirder effects out of it. I'll have to check whether that's in the latest package or not. caspercody, thanks for the vero layouts. I don't do vero for anything, so creating layout...

I apparently have a thing for delay/reverb circuits. I decided to do a true stereo reverb using PT2399. It's based on my Spare Room design, but it takes advantage of of the ability to cross feed the left and right signals and to do some cool cross channel-dependent modulation. It's not a small circu...

Super cool! I've been wanting to get into DSP effects for a bit, but I'm still mining the depths of PT2399's, ES560xx, and microcontrollers at the moment...

The 56028 has a couple of advantages: - Lower minimum delay time - Single Fadj pin/scheme that allows for more "traditional" LFO/modulation schemes - Space considerations The 14 ms minimum delay time of the 56033 can do chorus-esque, but the 56028 gets much lower. This chip is the same ch...

There are quite a few components, for sure. Honestly, the 0805 size resistor/ cap package isn't hard to do by hand. I do all my soldering by hand.

Very cool - thanks for posting. I looked around for the ES56028 chip and noted that it comes in a DIP package (ES56028E) which means you could probably construct this with through hole components on vero. The vero layout would likely be large but not too bad to do. I've got some of the DIP parts fo...

I like to try to find effects where there aren't many DIY offerings and come up with something. Dimension chorus is like that. There's the DC-2 clones and the Dimension P and that's about it. I repaired a Boss CE-5 a little while ago, which introduced me to the ES56028S chip that Boss now uses in al...

Ah, it was the other forum, not this one. Here you go:

It's fair to say that I have been on a bit of a quest to come up with a variety of DIY-able reverbs. I did the T60 Reverberator a year and a half ago, the Spare Room and Riptide reverbs were last year, and now, the TBR. It stands for Tiled BathRoom and started life as an Ersatz Verben, but I did a f...

I have completed a new project for this wonderful community. Riptide is a real spring reverb utilizing a blue Accutronics tank. The circuit is actually rather straightforward, but I haven't seen any fully documented DIY projects for one, so I figured I would make one. The decay time is something in ...

I did a little more development on it, but it's still mostly schematics and pseudo code. I should revisit it. I don't think it should be overly hard, I just keep getting distracted

I have just finished up another project for the DIY community that I am calling the Spare Room. It is based on valvewizard's Equinox II reverb, but with a few notable changes. The first is that I take the output of the first delay stage, low pass filter it, and feed that into the input of the second...

I created this project while messing around with the ES56033 chip that I used in my Stalker Double Tracker project. I figured out a way to get some modulation, but the chip seems to have an internal compensation circuit, which means you can't control delay time the same way you can on PT2399. Howeve...

I don't usually design boosts or dirt box, but I thought I would have some fun with the Fuzzrocious Ram the Manparts circuit. I've made a significant number of changes, but thought I would pay homage to the name of the original with Rochambeau (or at least that's what my Southpark watching friends t...

I did look at that chip, but it was a little harder for me to find, and the documentation I found seemed to indicate it was an older chip. That may not be true, but boss uses the bigger brother of the es56033, so the parts/ manufacturer should be relatively robust.
