Back in the day, Ibanez chose to manufacture a unique custom taper dual-gang potentiometer to build their WH10 wha pedal.While V1 and V1.5 kept the same vintage type potentiometer built with the same specs by the same manufacturer through all the 80-90’s, V2 and V3 are currently being built with a new version of it.--Sadly, the “new” version of this peculiar potentiometer - which in my opinion is one of the few keys to nail the V1 tone - doesn’t match the same “taper” (resistance per rotation degrees) of the vintage. Also, V2/V3 pots aren’t as durable and consistent as the vintage ones. I noticed a way wider tolerance, which makes it impossible to build two identical sounding effects.Because of all those reasons I spent years studying and analyzing the behavior of those two versions with countless comparisons and measurements. Many many vintage potentiometers have been torn apart for this purpose. After a very long time, and after hunting for the best quality and consistent potentiometer manufacturer in Taiwan, I am finally proud of announcing my V1 REPLICA POTENTIOMETER.It is a direct drop-in replacement. Same taper, same specs, same consistency.*fits any type of WH10 pedal: V1, V1.5, V2, V3, WH-X
