As soon as I read "Wawa hoagiefest" I knew it had to be a Philly thing. I grew up and lived there for 40 years before moving to New England for work. I always chose Pat's over Geno's. 😋 That's a beautiful looking enclosure. Can you say a little more about how you did it?

Thanks for that, Betty Wont! Dead End FX schemes are so hard to read. But that was a big help! Just a resistor and a cap. The Lola is +/-15V and the Duo is +9V. With the values used in the Lola, I got what looked like a LOG transformation of the triangle in the Duo (shark fins). Decreased the...

I'll pass on the beh... :rolleyes: Anyway, I already have a few other mods wired up to the Duo board, so I'm sticking with that. According to this... https://www.electronics-tutorials.ws/opamp/opamp_7.html ...a single opamp can be configured as a differentiator which appears to be capable of...

@Robert - Since the Bi-Phase originally had a sine/square selector for each of the LFOs, was wondering if you explored doing the same for the Duo-Phase. https://www.pedalpcb.com/product/duophase/ My cheap o-scope shows a triangle LFO in the Duo-Phase. I poked around a little but could not find...

Here's a direct link to the build doc... https://static1.squarespace.com/static/6761e66815296a34d2da56e3/t/681007e96be7b2512a68fe06/1745881084398/EverythangBuildDoc2025.pdf Agree, series/parallel is cool. I'll be doing that on the Duo-Phase I'm working on. But it looks a bit more involved for...

So, I was perusing the schematic in the build doc from here... https://www.otherpedals.com/shop/p/everythang-vibrato-phaser-tbntt ...and trying to think if there might be any mods that might make this thang even cooler. So, how about adding a duplicate of the LFO with a switch so that the...

Nice looking build! I'm currently working on one of these, too. Plan to squeeze it into a BB2 enclosure so I can have it UV printed at Tayda. You might be able to get more aggressive sweeping if you mount the LDRs facing up and lower, closer to the PCB, so they will also get the reflected...

For starters, I never buy PCB mount style pots. I always buy pots with solder lugs, which seem to be much more widely available from various suppliers. I solder about 4-5 cm of bare 22AWG bus wire to each lug so it can be mounted to the PCB. This also makes them more flexible when positioning...

Nice, clean looking build. I plan to try putting my straylight build into a BB2 enclosure, maybe even a BB, so I can have it UV printed by Tayda. Since the height of the bulb is actually less than the taller electros on the main board, you may also be able to trim down the sides of the light...

When I use two status LEDs of the same type and color, I connect the anodes together, connect the cathodes together, then treat them as a single LED with a single CLR. Like others have said, I work out the value of the CLR by trial and error on a breadboard or with alligator clips. Occasionally...

A build document would be nice, wouldn't it? Footprint looks like it could be a Lorlin SP12T.

I do work kinda slow sometimes. But I had to verify a couple of things before I ordered my enclosure. So, here's the plan... S/P - Series/Parallel (as above) - DPDT toggle (on-on-on) Switch to Parallel for stereo operation. Gives a different feel in mono, too. 2/4/6 - Number of filter stages...

Yes, both inputs in parallel for stereo, sorry. I'm locked into doing this series/parallel mod. I don't think I will ever need or use a second external input jack if I add the S/P switch. In parallel mode the input gets sent to the inputs of both phasers internally. Also, by using a switching...

For stereo output, I don't see why you would use the secondary input unless you are mixing two different instruments/inputs, one to the first phaser and a different one to the second phaser. Is that what you are doing? Secondary input makes total sense if you want to be able to treat it like...

OK, got it (duh). Input goes to phaser B first, then to phaser A. I got confused going from left to right on the schematic. All good... 😎

Yep, the trimmer looks like it is for the input gain. Might be useful as an external control, maybe? I need to build myself one of these. Had a blast back in the day playing around with Dean Hazelwanter's pitch shifter project which used to be at GGG. Looks like that's what the Robot is based on.

So, anyway... I am excited to build the Duo-Phase. Got the PCB, finally ordered needed parts and started working out how to do a couple other mods I'm interested in trying. But I've hit a roadblock. The reference designations in the PCB layout image on the first page of the build doc seems to...

I am curious to know from others that have already built the Duo-Phase with the extra I/O, how often do you really use the Phasor B input, and how do you actually use it? I'm thinking of leaving it out because, other than mixing two different instruments together, I'm not seeing how else it...

The Duo-Phase operates with the two phasers always in series. I'm thinking it would be cool to add a Series/Parallel switch. Something like this... Seems kinda like a simplified version of the Phaser B input switch on the Mu-tron. Moving on to add the dual inputs/outputs raised a few...

Thx! No vinyl at all. It's all UV printing. The enclosure, paint, drilling and UV printing all by Tayda. The green color on the face is just the color of the enclosure showing thru. Also, for the UV printing, I almost always get the white layer printed twice so that the enclosure color doesn't...
