Couldn't decide if this should be in the Amps or Effects section; but it is amp specific so here goes. Has anybody else noticed how increasing the Pickup Loading on the Studio Pro can make a big change to the sound of pedals such as Big Muff Pi? It really kills to volume; I guess it's an impedance thing but I'm wondering if this is all Fuzzes or just the big muff? Not so obvious on my TS or Small Fry but need to max out the Big Muff even to match the clean level when at maximum pickup loading. Not the most subtle of sounds when like this.
