Am I doing something wrong? When I insert the ‘63 reverb pedal before the amp in the Mustang plug in it does not sound like a spring reverb unit and is very weak. Doesn’t sound at all like my outboard reverb unit. Even with all the dials cranked it’s not very strong and sounds nothing like a spring reverb. I’m a first time user of Fender Studio Pro so hopefully I’m doing something wrong. Same with the 65 pedal
