Blues Deluxe Reissue dead reverb

[g1]

I HAVE signal t TP22... I can touch the return wire tip with my finger and control the volume of the hum with the reverb pot so the pot is obviously ok.

If these statements are still both true, then everything seems to be functional and it must be a matter of level being too low somewhere.
You will probably need to inject a signal and find out where the level is getting lost by measuring at the test points as Jazz suggested in post #12.
See the notes at the bottom of the schematic regarding test conditions.

I had to order a J113 to replace the one I broke. I'll get back on this one when my parts show up and check my kevels through the reverb circuit.

Unless the board is removed and too much trouble to put together, you are better off troubleshooting and checking levels with the Fet removed. It only functions to turn the reverb off.
By checking with it removed, you eliminate the entire switching circuit from the equation.

My J113's came in so while replacing Q2 I also replaced U2, reverb IC 4560. Problem solved. Lot's of 'verb! Thanks to everyone who lent their skills and time.
