Well soon I'll be getting a Marshall regenerator, which contains a jack to plug an expression pedal into, so I'm looking into getting one

just wondering which would be my best choice

I'd imagine all expression pedals are similar in quality, but I'd just like to double check

I use a Roland EV-5 with my Sweet Sound Mojo Vibe. It works as expected, not much else to say. Although you can adjust the range of sweep which is kind of nice.
