I can’t remember which pot I went with @MichaelW - it might have been a B10k. I felt the mod makes the mix pot more useful when it is at a higher level. You loose the original dry sound without the mod.
Here’s my build. I put it on a switch to alternate between the mod and normal function. Next time I wouldn’t bother I would just clip pin 3 and leave it at that.

Very nice looking build @MichaelW - it’s definitely my favourite delay.
I would also advise you to have a look at the mod to the mix pot which IMHO makes the pedal sound even better.
Another thing about that BJFE, I personally hate how high the footswitch is. I know that means you can get a battery in but I think it ruins the aesthetics of the pedal.
That is not ugly @vigilante398 - beauty is in the eye of the beholder.
That looks like a great way to get into building tube based pedals. One without a massive parts count.
