Two questions

[Nyklus]

Im about to add a new plug to my delay pedal. It's for externalizing control of delay time for an arduino,

I have the hole cut and connector in place. I want to wire it up but my concern is that i will be messing with the original resistance of the delay time pot by adding all this metal to the circuit. I'd like this thing to be consistent.

any advice? Think i should add an on/off by putting a switch between the lead of the pot to my new control?



also

other question.

I'm taking apart my A/DA
i found that there were holes for new switches but i drilled them before realising there was a lot of components right underneath leaving me maybe 1 half inch or a little mor to fit in a latching pole throw switch.

Does anyone know of switches for sale that are extra squat? Preferably with the leads coming off the side?

I'm a little baffled by your question. Do you know what the delay time pot is inside your delay pedal, or how it works? And does your scheme for controlling the delay time with an arduino match what the circuit expects from the delay time pot? I.e. a variable voltage, or a variable resistance or whatever? It's likely not to be happy unless the arduino connection sends it what it expected from the pot.

I'm completely baffled by the wondering about "adding all this metal to the circuit". Metal per se doesn't have much effect at all.

Why? What objective do you hope to reach with this?

Good that you didn't drill them with a laser then.

Wire in the range that we use in pedals is something like 10-30 ohms per 1000 feet. Even if you used something like 5 feet of wire, you'd be under an ohm or resistance. Only you know if this is going to mess with your delay pot since you didn't provide a schematic for the pedal, or say what it was.

I'd you can find toggles, you could try to find slide switches. They often come in small packages and have lugs/pins coming out of the side.

I once drilled a hole through a wall before realizing there was a 60-pair telephone cable where the drill came out.

It is a mistake you (try to!!) only make once.

Ok, Thanks for your response about the metal adding resistance. To answer your questions.
This pedal is my guyatone delay MD-2 and flip delay. I really like these pedals when you modulate the resisitance of the delay time so i've already modded my flip

also, it doesn't seem to unrealistic that squat pole throw switches exist and i really like

also I'm taking apart my A/DA because i want to change the inner trim pots and

You want to change the inner trim pots with a switch?

I am completely baffled as to why you would do this and what you think you are going to accomplish by doing this.
