Notakliche bits

[zeropluszero]

Hey all, I'm hoping to finish off a notakliche feeding into an uberdrive this weekend, and just have a couple of questions.
I'm looking to use bat41 for the main diodes at the bottom of the PCB - I can see the PCB is labeled with a stripe for what I assume is the cathode - although I also read that some germanium have their stripe on the anode...so now I'm paranoid - does the PCB stripe label cathode or anode?




Also, in regards to the LEDs, are these an extra clipping option? or an additional with the D1/D2 diodes? Could I populate D3/D4 with Bat41 and D1/D2 with germanium and have both options?


Pictures for reference.

Your diodes are fine. Technically they should be oriented the other direction to match the silkscreen, but because of their arrangement in the circuit it will make no difference in this case as long as you install them both using the same "standard" ...

D1/D2 are always in circuit, D3/D4 are added in parallel when the toggle switch is flipped.

There has been some discussion about how much of an impact the LEDs have when added in parallel with the clipping diodes. I highly doubt it'd be worth adding germanium into the mix there.

Could I put the bat41 into the LED sockets d3&4 and put germanium in the D1&2?
I guess I'd sort of hoped to have that as my configuration. Probably should have just modded a regular kliche

 

[Robert]

You certainly could, but I don't think there is going to be much audible difference between the BAT41 and Germanium diodes.

Ideally what you'd want for the most noticeable tonal change is a diode with a higher forward voltage (LEDs) in D1/D2, and lower forward voltage (germanium or schottky) in D3/D4.

The switch makes the dirty path louder and adds the LEDs in parallel with the BAT/Germanium diodes.
Honestly, what you're looking for would be a regular clipping switch that actually switches diodes in a way that makes sense.
The LEDs will have barely any effect on the tone really, as the BAT/Germanium diodes already clip the signal with a much lower threshold here.
What you could actually try is putting the BAT/Ge diodes to D3/D4 and try some silicon diodes or even LEDs for D1/D2.

Ah you both had the same idea haha. I guess good thing I socketed these, I can give those combos a try.

That way makes sense because the switch would compensate for the lower volume of the schottky/germanium diodes vs silicon/LEDs. But the clean/dirty balance won't be the same regardless of setting compared to a normal Klon/Kliche. Still could be interesting to experiment.

 

[jwin615]

I'll echo, put whatever has the higher Vf in D1/2

Just to be clear, while this makes more sense, it is not how the original is configured. The original uses the values as printed on the PCB.

I'd like to try the circuit with the same values in R15/R16 to see what impact (if any) the LEDs have.

Yeh that's cool Robert, I'm less interested in this being a 'notaklon' pedal so much as it being a klon style with options built into the PCB.

Where's the (full) schematic at?

I wanted to DL a copy that isn't cutting off the tail end of it and searched "notakliche schematic" and nothing came up, ditto with "Notakliché..."
Checked this thread:

NOTAKLICHÉ PCB - Arriving Soon!

https://www.pedalpcb.com/product/pcb681/

forum.pedalpcb.com

and it's not there either.

I checked the missing build-docs/schematics thread, too.

Maybe I haven't had enough coffee, I'm usually pretty good at rooting these things out of the threads...

It's in the build doc.

 

[Feral Feline]

There's a build doc?

EDIT: Joking aside, I didn't even think to look for a build doc. Ooops.





Thank you spi

So I got my new enclosure in the mail after fucking up the drill template on the first one (that SUCKED) (Yes I'm aware of the input jack being very close to the switch & diodes)
I'm looking to put the order switcher in place which I'm clear on the wiring for - Just need to know if the far left of the notakliche 3PDT breakout is where I need to connect the S1 connection on the 3PDT order switch, or is this different given its buffered?

 

[Nostradoomus]

use the in/out pads on the top of the board

 

[zeropluszero]

Oh
Do I make all 6 connections from the notakliche to the 3pdt then?

 

[zeropluszero]

So this is what I think is right- With the Yellow being ground connections to the PCB from the jacks, Im not sure where S1 and R1 need to go for the notakliche, whether to the outer sides of the footswitch, or to the in-out at the top of the board.

 

[Nostradoomus]

That won’t work, connect the switch like normal to all pads on the 3pdt board. Use the top in and out pads to go to S1 and R1.

 

[zeropluszero]

Ok, I haven't added them in yet, but this is my plan, should I connect the input jack ground to the boards, or maybe unnecessary?

 

[zeropluszero]

Seems to be working. a load of squeal coming from the kliche if I max out the dials - my initial suspect is that the clipping doesnt like that - so...just dont do that.


LEDs in D1/2, Bat41 in D3/4.
