Nicolas,

You were right, the issue was the trimpot, the circuit works correctly now that has been adjusted. The circuit is a little noisy, but I think that might clean up a little when I put it in the case.

Thank you for your help.

Hello, simple question:

Was the trimpot open? R4 (minimum aperture possible)

Then, with your red Led, I noticed that in my case you have to reverse the polarity, otherwise I had no sound.

Try that

Edit : i see you reverse good the polarity, so it's good. But try to reverse otherwhere.

On another quality blue led, normal polarity was needed for it to work, weird (in my case).

You can check the polarity of the Nsl32.

You are in the right direction.

But there is a white point (normally) which indicates the mass, and you have to solder it to the opposite of the + of the pcb (on its right)

Hi Nicolas,

I’ll check the trim pot - the kit doesn’t come with any notes regarding setting up the trim pot, and I haven’t touched it so far.

Thanks for taking the time to look over my pictures and comment. It doesn’t sound like there anything obvious wrong, but I’ll double check the things you mention. I think I need to put an audio probe on this to see where signal is lost. I haven’t done that before, so I need to do some reading to find out how.

I’ve checked over the cabling, and as far as I can see, the foot switch is wired as in the wiring diagram. Please can you be specific as to where you think I’ve made an error?

Thanks,

Robin

Thanks, I’ll check it out.

Hi Max - Thanks for your offer of help. I’ve attached as much information as I can, please let me know if you need anything else.tremolowire.pdftremoloschalt.pdf

Hi,

I’m building a Das Tremolo kit, finished the build and am testing it. I hear guitar on bypass but not with the effect inline. The led pulses and I can hear the pots making changes to low level noise on the amp side, but no guitar sound. Can anyone advise me please?

Thanks,

Robin

Hallo,

Ich baue ein Das Tremolo-Kit, habe den Bau abgeschlossen und teste es. Ich höre Gitarre auf Bypass, aber nicht mit dem Effekt inline. Die LED pulsiert und ich kann hören, wie die Potis auf der Verstärkerseite Änderungen an leisem Rauschen vornehmen, aber kein Gitarrensound. Kann mir bitte jemand raten?

Danke,

Robin
