Well, some good overrall EQing tips is to be as gentle as possible with them.
I run my EQ just about flat.
Bass 5
Mid 5 (DON'T scoop it!!!!!)
Treble 6
Presence 4
Gain 5
This is on a recto. With an ubershall 4x12. But I also play in a prog rock band. So my EQing tastes will be different than yours. But even still I get a well balanced sound that sits perfectly in the mix. Know your instruments role in the mix. Thats key. When you paly alone thats one thing. When I practice I use a J-Station and use a recto amp model, and ALLLL the mids are scooped out. It sounds awesome, but when you play in a band that scooped guitar EQ will get lost in the mix and end up fighting with the drums and bass. My other guitarist has his EQ 100% flat except he puts his gain on 6-7. My bass player actually uses the subtractive EQ approach and he gets awesome tone. If in question though, just run it flat.
