[Solved] The Bluelay - volume problem

Hello all,

I have assembled Das Musikding's The Bluelay, which is a Deep Blue Delay clone. It works, and I like it.

There is one small issue: when I activate the pedal, the dry signal has a small but noticable volume drop. The delay signal stays at the correct volume.

What could be causing the volume drop? And to fix it?

Here is the link to the schematics: https://www.musikding.de/docs/musikding…elayV2schem.pdf

Thanks!

Thanks Uwe!

Any suggestions to what value?

Again, thank you Uwe!

I will need to order some parts and get to work.

Just realised I did not report back after this. I made a rookie mistake: I only looked at the schematics and not at the actual pcb. Right next to resistor R4 there is a trimpot on the pcb (mini trimmer 25k - R5), and that does exactly what I was looking for.
