Yes, i tired that, but I also want to slightly adjust the EQ at the same time, just to give a bit more edge to the driven tone.
I'm this close to getting the HX FX, so it's all laid out in front of me, but this evening ive just programmed in the other two 'unique' effects in to one patch. So now i have 5 footswitches controlling 4 unique effects, inc one going between the two BDDI's. This is 99% of what i need for a gig.
EDIT: I know i can also set the Treble (for example) to the same foot switch but my way seems easier to tweak.
