Reverb gain on Fender Princeton 112+
I picked a '90's Princeton 112+ "project" amp. Replaced knobs, reverb pot and spring reverb tank.
Two issues I'm hoping someone can assist me with:
1. At "zero" position on reverb pot there is no reverb. On "one" I get full reverb. No difference between 2 and 10.
2. The amp (reverb off) seems quite "hissy" to me.
Any suggestions (other than scrapping the amp!) will be greatly appreciiated!

I assume you already got the schem and the manual.
Just in case not:
As to problem 1: Sounds suspiciously like "wrong pot" that means either
wrong resistance (It should be 50 k) or wrong taper (>"B")
since this product is of (more or less) US-origin this should be a "linear" one , not one with audio/log tape. (In Europe this is someway different)
As to 2) : Right now I can only guess.
I'd check first: what else did you replace ?
then : Proper solder joints
then: all small caps back in place correctly ?
Hope this helped.
