My Flashback and Ditto mini have very different footswitches
The Ditto’s footswitch is about 5 mm taller than the Flashback’s, and has a much smoother feel. I really have to press hard on the Flashback, and it is difficult to time the click precisely. Do I have a defective one, or do all Flashback pedals have this stiff feel?
