That annoying moment when you buy a Big Muff pedal from GAK and - on delivery - you discover the box (correctly labelled as Bass Big Muff) in fact contains a guitar tremelo pedal. Grrrrr
Fortunately GAK were quick to contact and offer to send a replacement plus a free collection of the erroneous pedal. So, all in all, a nuisance but dealt with quickly by GAK customer service
