I'm thinking spin a rev with oversized enclosure holes and use calipers to measure x and y distances from jack thread to enclosure cutout.

F Why use smd/hybrid caps some of the time and the for the rest?

What's the radius on your rounding in the corners?

From what I see, the clipping diodes will form a DC path from vref to GND when the diodes are engaged. I would make the GND side of the diodes Vref assuming vref has a big bypass capacitor >=47uF.

Good idea

Sorry to push back but the volume/blend has worked for me on previous builds. It's true that volume loads down the blend but that's why volume pot impedance is a magnitude higher. I could increase further to reduce interactivity though. If I follow the opamp with volume then my output...

Yeah I have the big muff wiper feed direct into a non inverting buffer. It worked on the last rev. SO did the blend and volume pots. I removed the blend pot to see if the volume control was acting as an antennae, somewhat is the case. After lowering some gains and the output bleed resistor to...

I am fresh out of college. Less than a year deep in work. There are people on this forum who also work stem and for much longer than myself. Humility goes a long way. It's arrogant to assume I'm the smartest in the room. Furthermore if I'm building circuits in my free time on top of the...

I measured wiper to each end at both CCW and CW for the blend pot. The level pot loads down blend so that 10k5 become 9k5 at max wet. SO upping my level pot to a 250k or 500k could help.

Delay Out and Dry are fed direct from opamps. The opamps are biased to Vg, the DC midpoint. Delay out also feeds the feedback path which presents a minimum impedance of 1k.

It is a custom layout and schematic. It's NOT high gain nor high impedance so I'm apprehensive that bleed is a crosstalk issue from layout. But, I can't see a bleed path in schematic.

WHile this is a hobby project, I work MI so I have non competes against sharing the circuits I make 😔. Ik it's frustrating not having the circuit, I try to explain without pictures as best I can The blend pot is 10k followed by 100k volume. I will bypass the pots. Hadn't thought of that. Also...

Bout to vent... I've been troubleshooting a pt2399 delay with a big muff tonestack. Custom build. The blend does not go 100% wet despite it being a pot to pan between dry and wet signal. The pot measures continuity across rotation. There is a volume control directly coupled after. Then the...

Awesome. Thanks!

Yeah so if I settled for 1.5Vpk would that still be considered usable? The OD clips at .7ish (go figure) and there is clean 10.5dB (3.3x) gain after so 2.3Vpk theoretically. From an oscillation standpoint, I need to drop ~4dB from the sum of the volume and drive gain. I could subtract from...

Hi, Have a design where the gain product of the drive and volume control can introduce oscillations. I'm looking at trading post clipping volume for pre clipping gain. I am wondering, what output level is considered weak for a pedal? I usually shoot for for full swing so 3.5-4Vpk but if I had...

Also diodes will reduce signal level by about 10-12dB depending on Vf.

I would favor adding clipping earlier rather than later in the signal path. Prior to IC3A and IC4A. If the opamp clips rails I can't imagine diodes are gonna soften that.

The aion fx is doing some real weird stuff. Looks like there's all pass filters in it. Wonder why, maybe notching when summing the bands.

Becomes like the xb driver from tech21. They make great stuff
