You could use PCB mount jacks

I was wondering why a LM1458 is used in the Timmy (Tommy III) versus a 4558? My understanding is that it's a stripped down TS, so, why not the 4558? Building one now and plan on socketing the op-amp, just wanted to get some opinions.

Thanks! That makes perfect sense.

Hey Guys, I'm installing some new pickups. I have the attached wiring diagram. It seems weird to me that there isn't a ground wire from the volume pot to the tone pot. Is there a reason for this? It seems consistent across a few different wiring diagrams I've seen.

You would use the continuity setting on your DMM to see which posts on the switch are connected/not-connected when pressed/not-pressed.

Agree with Erik S, the LED on all the time is the biggest anomaly. Are you are running it at 18V? How are the voltages on your regulator?

Also check that your external momentary switch is the correct type, i.e., normally open versus normally closed.

Looks like the momentary switch in the pedal has 4 terminals? You should use your DMM to figure out what is not-connected/connected in both states of the switch. You might need to move your added wires or add a second set.

Given the time lag to problem, I would check your transistors. They might have come loose from those sockets.

Gorgeous build! Really dig the aesthetic of this one, white knobs on black is killer.

I've got extra Ibanez BC-9 boards, if you are interested. Similar foundation as the Purple; you would just have to mod in all the extra switches and such. https://www.madbeanpedals.com/forum/index.php?topic=33837.msg325005#msg325005

Great build! I love this one, too. I did mine with top mount jacks too, but had to move to side mounts because of LFO noise. Glad yours worked out, but I wanted to give a warning that sometimes it doesn't :cool:

That pre-amp is loud by design. You can plug it into the effects loop of your amp and only use the power section.

This is the likely culprit. You could also try probing both sides of C3 and C4. Lastly, I have a 9V battery rigged with a snap and a barrel jack. Sometimes some pedals get weird noise from a particular power source.

The schematic is there in the Aion docs. You'd have to figure out which two components are jumped.

Aion has a DS-1 project (Comet) that has a lot of information about different mods. I'm not familiar with the mod you are describing, but I'd recommending looking over the documentation at Aion.

Because the breakout board is set up for a dual LED (the ones with three legs that are one color in the off state and another color in the on state). You have the leads from your two legged LED soldered to the off state pads.

I would cut the extra ground wire you have running from somewhere near the jacks to the switching board (the one next to the output wire). The ground from the main PCB will be enough.

If you have a dremel, you can cut a notch so that a flat head screwdriver can take it out.

Whoa, dude! Congrats. Analog delays are no joke, that is a feather in you cap, fo sheeze 😎
