I would say I was probably wrong about the ET not benefiting from a blend circuit, but I also don't particularly care for blended compression at the front end of a guitar anyway. (Recording is a different matter. I'm all about blended compression in post.)
Quote from: midwayfair on January 11, 2017, 02:43:54 PMJon, did I read an old post of yours correctly in that the Engineer's Thumb doesn't need an added blend? It already has it using the RATIO pot?
Don't just jam whatever compressor you like into a blend circuit. You need to make sure that the signals will be in phase at the output. (So you can't just put the Bearhug in the JMK Panner for instance without extra work, not that I think that the Bearhug benefits from a blend circuit given the short decay.) The 4:1 was set up to do the blend right. The fractional extra speed you get with an OTA compressor like what's in the the Wampler over a fast vactrol like the VTL5C1 is not really that meaningful when you're using the clean blend to retain the attack of the note.
If you want to be able to add any compressor (or other pedal) to a blend circuit so you can experiment, read this: http://www.geofex.com/Article_Folders/panner.pdf

That's beautiful! Really cool of drolo to allow his design to be used by delyk also.
Quote from: sturgeo on January 12, 2017, 03:10:45 PMI popped out the opamp and set the switch to bypass. No change.
OK, what about the buffer circuitry? I guess that is sharing the normal GND? can you bypass that to rule it out?

The noise is when any pixel is lit. Just a static text, you get noise. I don't think it's the I2C lines.
Just had a closer look, you've got the AGND & GND connected in the pic, does it still have noise with them disconnected?
Quote from: Timko on January 09, 2017, 10:06:57 PMGood! Hold tight and I'll hopefully get this remedied ASAP.
Building a looper was one of my 2 pedal resolutions for 2017 .
Quote from: sturgeo on January 10, 2017, 12:12:32 PMI'm having to figure that out as we speak. I have an idea, but don't want to share yet.
I looked at either the 16x2 or 20x2 but gave up trying to find a neat mounting solution.

With the Opto mute are you driving it straight from the IC or through a 1k resistor still, also are you muting with a delay before & after the relay switches?
Quote from: sturgeo on January 09, 2017, 10:20:30 AMAll of that is 100% accurate.
Looks good, very similar to something I'm finalizing however I'm using a LED alphanumeric display.
I guess this is what was being discussed here?: http://www.madbeanpedals.com/forum/index.php?topic=24225
Whats this issue with noise from the OLED? separate GND plane for AGND & DGND? is there only noise when data is being written to the display or is it constant? I'm guessing with the display removed its noise free so it isn't the I2C bus in general
Quote from: pickdropper on January 08, 2017, 12:49:46 PMI've been eyeing the MONO Acoustic + Electric + Baby case. A bit out of my price range.
Congrats on both! Beautiful baby and guitar.
I would recommend carrying the baby in a more padded case, though. I don't think that one's going to protect him well enough.
Quote from: Muadzin on January 08, 2017, 12:30:37 PMI have thought about this and theoretically, yes. I'm 99% sure we can with MIDI. I designed it so we could, at least.
That SO looks like something I could have used, before my Axe. I still might be interested. Could you daisy chain two of them together? For even more loops?
