A power box isnt an FX pedal. I didnt say no more gear. I said no more pedals. Maybe the odd bass here or there. I dont like whammies, and i have a choice of at least 3 compressors in the zoom. The extension cable is fine. All power supplies ( when unplugged ) and extension lead, when coiled up, all lay in the case. I dont need a power box, as i only have 3 power supplies. 1 power supply does the Boss, 1 power supply does the Zoom, and 1 power supply does all 3 single peddles.
