Remember this is an acoustical delay with pickups. you will need to isolate it from vibrations.
Good luck and take lots of pictures.
indeed! i'd like it to be as close to original spec as possible. I'm hunting parts still, got a show to play and working on a console and wiring so i got alot of time to collect parts. hunting down wood at the moment for the box.
i got a little paia headphone amp circuit hanging around. might be enough.
copper tubing sounds like a good idea. but would it change the sound?
packing peanuts are all over the place too!
