The only 2 issues I had were with the standing resistors (I've no vice so keeping them in place for soldering required bending the legs quite hard, which twice led to me soldering across copper tracks by accident. Pain in the ass to undo and still make it look well!)
The other issue I had was my insistence on fitting it into a 1590b. I drilled the enclosure to fit a battery and a DC jack. I stupidly (without measuring) put the DC jack at the top of the pedal and the battery at the bottom. This left very little room for the vero AND the belton brick. I ended up mounting the vero component side down and squeezing the lid shut, using PVC tape on all the internals to avoid shorts.
Its an absolute mess inside but it works and happily.....sounds fantastic.
If I were to make another I would....
Drill DC jack below the input jack
Mod for a true bypass with tails option switch (sometimes its nice o kill the verb instantly)
Long story short....If you follow the layout and double check every step you take, you can't go wrong. And in the end you'll have a cracking reverb pedal that you can be proud of!
