You can definitely test it without SW2 connected, just be aware that the 3PDT that switches between high/low gain also selects which level pot is being used. I'd recommend shorting the middle leg of your Level 1 pot to the output if you're going to leave the switch out entirely.

According to the schematic SW2 activates the LED for the high gain mode. The other poles for this switch will bring the high gain trimpot into the circuit and determine which level control is active. To jumper you can use an alligator clip or just solder a lead between the pads. I think a SHO...

Looks awesome, nice work on the grille cloth too!

Looking good! Love the potential of a wide open space.

Yep, continuity when depressed is what you want! The trimpot looks good too. I'm not familiar with the diode mod, but it's definitely worth socketing to try it out. Let us know how you go!

I've done this for the Dark Rift delay and it's heaps of fun! For the oscillation footswitch you want an SPST momentary NO. That way pressing the footswitch will short the feedback pot via your tripmot.

Current draw is easy enough to find out with a DMM. Just hook it up to the pedal's power jack and select the appropriate amperage range on your DMM. It'll be under 1 amp.

Substituting a 10nF will be totally fine.

Blue is a double link. It means both of those links meet there.

Good to hear, thanks guys!

That looks sick! How were they to deal with during the process?

They're probably ok then. Do you have any spare TL072's you can try? I don't think they're the problem but they're socketed so worth checking. Squeeling sounds more like it could be a bad cap somewhere. Double check all your component values, especially around the volume and gain pots. Do you...

Q1 (2N5457) is out of production and feels a bit suspicious. Where did you get yours from? If it's a fake that could be where your problem is coming from.

As a general rule you should stick with what the pcb says.

From my experience, making assumptions when it comes to drilling will only land you with an unusable enclosure. Just because circuits have similar controls and enclosure sizes doesn't mean placement will always be the same. I might just be overly cautious, but I'd recommend drilling an...

Woops! You're totally right, sorry. Alternatively you could do two 10nF in parallel and that would be 20nF

if you wire two 47nF caps in parallel that will give you 23.5nF.

Good luck! It's a relatively simple circuit so if you need some troubleshooting help there's heaps of people here to help.

Hey Chris, both will work, but MLCC are generally considered to be higher quality and more robust than your standard ceramic disc caps. As long as the value of your C2 cap is 220pF (or there abouts) and is rated to at least 16v, you're ok.

The function of the charge pump is affected by both the IC and the circuit. For example, MAX1044 is typically used as a voltage doubler, but can also be used as a voltage inverter or divider depending on the circuit. For pedals running on 18v, 35v caps should be ok. 50v caps will also work, but...
