My understanding is the high end loss associated with guitar vol Pot has to do with impedance interaction with pickups inductance, and the capacitance in the long cable from guitar to pedals/amp. Not sure what context you’re wanting to attenuate volume, since what’s before/after will affect it...

the effectiveness of 1 and 3 is highly dependent on the input impedance of the following circuit. (Basically, forming a voltage divider between the in line resistor and the input impedance (resistance to ground) of the following circuit. 2 is still somewhat dependent especially if the input...

I chose the Jr pcb for size (1590B!). I don’t recall what all the differences were between them. The circuit does definitely invert phase, so a typical blend won’t work as the center of the sweep will partially cancel out. The little vero board in the corner is an inverting op amp buffer...

Here's some phone clips playing through the Double Analog Octave pedal I made. Hope it's enough to give the flavor of the concept. The higher octave isn't always apparent but, that mode always gets nastier. First clip (all Les Paul Neck pup): Clean Clean + 1 Octave Clean + 2 Octave Second...

It sounds roughly 2x as bad as the green ringer with chords haha! I’ll try to record something soon

Since you guys are octave up enthusiasts, I thought you might appreciate this. I recently built a couple double-analog-octave up pedals. Basically it’s just 2 green ringers in series, with a toggle to select one or both and of course the footswitch to bypass the whole thing. The second circuit...

Agreed on the neatness of the vero build (as usual). Do you cut the pot wire to precise lengths? If so, what is your process for determining the lengths? When I build vero I usually just guess at the lengths based on roughly where I’m gonna put the pots, always adding a little safety length...

I think the OCD has some op amp clipping (before the mosfet clipping). That can sound kinda thick. Upping to 18V or maybe adding some blue led soft clipping leds would reduce or remove the op amp clipping. No idea if the TL op amp clipping is part of your “fatigue”, just a thought to try. Let...

Except that V1 vs V2 you can actually hear easily, unlike the magic diodes haha (my opinion).

FYI - there two versions of the Bluesbreaker that delineated pedals are based on. The main difference is two resistors in the first op amp stage. For example, KoT is based on the V1, and the Morning Glory is based on the V2 and has more aggressive upper mids and treble. It is possible to put the...

Ah ok. That one has 10 pins, right? Are you thinking just a board that mounts the switch and then 10 wire pad holes for easily attaching wires?

Just to be sure l, do you mean the 9pin rotates (8 positions)? If so I have that footprint in diptrace and could design and have some pcbs shipped to you. Unless of course PPCB wants to make one.

All advice should be taken with a grain of salt and further your own learning. What is the purpose of C11? Capacitors in the signal path like this let the AC voltage audio signal through but block DC voltage. This is important because the FV-1 section is biased at a different DC voltage than...

I don’t see anything that I can say for sure is ruined on the pcb, but I would definitely suggest reflowing a lot of those joints to clean them up. Make sure there’s good contact and no bridging. I’m guessing the ringing only occurs on one of the 25k pots (density or dilute (called mix in the...

I helped a friend finish a tremolo factory recently. It was quite unpleasant as the layout doesn’t seem well thought out since the jacks would interfere with the pcb. He had followed the drill doc. I guess low profile jacks could have fit above the pcb (when viewed from gut), if drilled all the...

Great, thanks!! I already put in an order like this a few days ago based on the confidence I got from yours and Robert's replies!

Sweet! I built the Fuzzdog version which has some mods baked in - toggle sw between 1 or 2 octaves down, and output volume boost built in. Still a 1 (or maybe 2 ) trick pony, but a little more useful. But for something to plug in and having fun, you’re already there!

I’ve built the blue warbler. It has a standard trem mode and warbll-y vibrato (like the Bigfoot fx Magnavibe sound). Which is kinda cool in its own right. Honestly I like the idea of the dynamic depth, but I haven’t played with it like that enough to really say. I think the nightwire looks...
