To add a Dwell control like on the
standalone reverb to a Fender amp
with reverb, remove the 1 meg resistor and replace it with a pot.
One end of the pot goes to ground and the other end
goes to
the capacitor - just like it is now.
But the wiper (middle lead) of the pot goes to the grid
(pin
2 and 7) of the tube.
The existing wire goes under the board and attaches to
the
existing 1 meg resistor and 500 pf cap.
