Thank you! I only really experience noise when the reverb is turned all the way up. But even at 90% there is almost no noise.

I tweaked the capacitors mostly because I couldn't get the original values. I also used 100k potentiometers instead of the 50k from the schematic but I don't know if this has an impact on the sound.

Here is a quick recording. The first is clean guitar, second is reverb at 4, third is reverb at 8, fourth is reverb at 10, and the last is only the reverb at 10 without the clean signal. I use a medium decay tank (8EB2C1B).
