This is a tip for anybody interested. I recently acquired an EHX PF, and noted in the video that Bill R made a brief comment about using the Exp pedal input to create pitch glides. I gave it a try last night, and it is a powerful effect that isn't really highlighted in the video. You can create pitch glides to selected intervals that vary in speed with the position of the expression pedal. Since the PF has selectable musical intervals, this can be a very useful and musical effect.
Both the VG-99 and GP-10 already have pitch changes selectable by string for B-bender effects that can be assigned to an expression pedal. When you combine that with variable speed poly glides using the PF pedal, it is a slice of Country heaven. Takes a bit of practice though, you get out what you put in.
Also on the GP-10 you might add a Slow Gear or similar to delay the attack of notes to make it more authentic.
Check it out if you get the chance.
