Hey there, I recently bought an EHX Holy stain with the understanding that i could use it with my Soul Press via expression output. I've never used an EXP pedal before so i'm not sure what i'm doing wrong. Basically i'm only getting half of the 'amount' sweep (i tried adjusting the bottom value on the pedal + i'm using standard patch cables) Is there a special cable i should be using? or is the soul press just not usable with the Holy Stain? Don't really wanna buy a stand alone exp pedal so really wanna figure this out. Any help would be much appreciated.
