Anyone use this boost? I have a real xotic RC and I'm having a little trouble matching it on the axe-fx. Seems like I have to really turn up the level of Esoteric RCB on axe-fx to match the real one. Am I doing something wrong? I notice that on the BB preamp (axe-fx model) I have to turn down the level a bit to match my real BB preamp pedal. Any ideas?
