Hi Res pictures...

Unfortunately, I won't have time to draw the schematic. Maybe someone else will do that?

What more is needed?

I'd really like to see, what's different in the version one ("SYOD1") and in the new SYOD3, which combines both voicings of the older versions.

Version 2 is all smd. As my wife is in hospital, I won't have time to do the tracing myself but I will take some macro shots. The pedal doesn't sound better than the old version, but it might have more headroom, as it can be used with bass or power humbuckers without any distortion. The clean boost ...

Just ordered version 2. I will post photos and schematic next week

Effectsdatabase lists 5 Chaser pedals and their names are all similar to Boss pedals:
Maybe it's helpful to find out, when these Boss pedals were released?

Is the enclosure identical to Boss?

Please post some photos here!

Which Biyang phaser are we talking about?
The old silver PH-8 was an exact clone of the MXR Phase 100

J = +/- 5% tolerance

One idea: Add a switch that disconnects the Mosfets from Vref. The second opamp will do the clipping now. Try different opamps, maybe OP275 (as in the Black Cat OD-1 "Freddie Fuzz"), AD712, rail-to-rail models or very old ones like 1458. But first, replace the opamp with a socket... https:...

A lot of marketing bla bla. Maybe it's just a tube screamer variation with a clean blend. Maybe like Voodoo Labs did it, or with a summing amplifier, as in my Rose Screamer.

Wow, great project! :applause: :applause: :applause: :applause: :applause: :popcorn: If you want so improve it further, work on the readability of the layout. The best program in that regard was DIY Layout Creator V1 - it had some flaws but it was quick and simple, too. I never use the newer version...

I built the original sweet honey od and added the voice control from the zendrive. Very useful!

Sure. Leave enough space for a rotary switch for various clipping arrangements. Or use a simple dpdt switch for two sounds. A dpdt on-on-on can be used for three sounds: One side of each diode combo is hardwired to the circuit, the other sides go to lugs 1, 4, 6 respectively. There's many combinatio...

What about a 9v opamp version of the Blackface Deluxe Reverb, including the tremolo section and a Belton-IC for the reverb?

Photos of both sides of the pcb. Maybe some shots against a bright light, so that you can see the connections through the board. And you should write the parts list, as it's hard to read the values and colour codes from photos. If you're in bright daylight, a smartphone camera is a very good tool fo...

Hiss might be a bit lower, but...

Things are boring these days. PedalPCB has everything already...

*BUMP*

I'd really like to see a schematic for this one. Maybe it's just a variation of the tube screamer, but a very good one.

yupp, that's the one I remembered

Does anybody have a vero board layout for the quad opamp version and true bypass?

I'd like to convert this pedal to true bypass, omit the second output and cut out the "jack pcb" completely. But I don't really understand, how the circuit on that jack pcb works. Is "delay out" on the main pcb the output of the circuit? Or is that just a signal with vibrato, whi...

Have a look what "corne" posted in the german forum musikding.rocks:

I think he uses a kit from tube-town.de for the midi controller
