For the money the vox 845 wah pedal is a no brainer.
basically the 845 is the 847 without the fancy finish but in all other respects its the same quality and build with the same performance features. Its ok paying out lots of dosh for all singing all dancing units with other peoples names on them but at the end of the day you get the same basic effect. Vox products are already good quality at a good price and now the 845 is the go to wah at a great price.
