Thinking about adding a tremolo pedal to the rig. I've used the likes of Empress and Diamond in the past, but I use trem so sparingly that I don't want to dedicate that much space, and if possible not that much cash either. Would really prefer something MXR-sized. Any recommendations? A couple I'm currently considering are the EQD Hummingbird (bonus points for top jacks!), and the old Catalinbread Semaphore if I can find one. Want something that can get fairly choppy.
