1) Switch (on the case or even internal) to remove the “dry” signal from the “synth” Output when the effect is turned off (does anyone really want a totally clean guitar signal going through their PA?)

2) Ground lift switch on the case (like Digitech does with its harmoniser pedals). PA lead grounded to the guitar signal ground within the pedal is a recipe for ground loops and hum!

OK- you can get round both of these with an AB pedal and a Ground-lift box (or modified cable) – but these features should have been built-in!

Otherwise – great pedal!
