I bought a used Mission Expression pedal a while back on ebay and have never been happy with the taper of the pot. It seems to go from off to on but the space in between is a no man's land. Looking at the calibration bar on the Kemper, it looks like the pedal has an audio/log taper pot instead of a linear pot.
I have been quite vocal about how shit this pedal is in the past but maybe I have been wrongly criticising it.
I was about to change out the pot for a new one so I loosened the nut holding it in place and lifted it out (still fully wired) just to take a look at the back of the pot and see if there was any specification markings on it.
WOAHA hold on Tonto - it says Dunlop and when I look up the part number online it comes back as 10k linear pot for Cry Baby Wah.
There are two possibilities here:
1 - (and probably most likely) the guy I bought it from had tried to change the pot before and fitted a Dunlop Wah pot which in theory should work as it is 10K Linear just like the Mission. If that's the case his soldering technique is fantastic because it looks like factory soldering.
2 - the reason people say the mission pedal feels like a wah is because it IS a wah. It is literally a Crybaby casing and it may even be a Crybaby pot. Which would make the retail price of the EP1 a total rip off. i.e £130 for a Crybaby with most of the circuit removed V £80 for one with everything still in it but you can take it out yourself and change the jack socket from TS to TRS for about £4.
Could someone with a Mission expression pedal take a look inside and tell me if yours also has a Dunlop pot in it?
