When I had a Quick Rod, I basically set all the EQ, including presence, from 10 o'clock to 2 o'clock, and it sounded really good. I could bounce between the 3 gears and go from Neal Schon to Zakk Wylde sort of tones, drop the B+ and get that VH-ish squish. Its percussive and bright, but to get it to be harsh I would really have to push it weirdly.
Admittedly, I don't know much about the Rectoverb so I won't comment on it. But if you can, I'd like to hear a clip of your Splawn with the EQ set to noon to get a base of where to go from there.
My initial message might've seemed rude, but I would like to help you get to a happy place with your sound.
Also, can you provide links to sounds you are aiming in the direction of?
