Oddly

Hi folks. I've just got my hands on a Laney R3 165w combo - it's maybe 6 years old - I think it's now rebranded as the RB6( but with a slide-style graphic eq now instead of the dials). I'm getting a pretty decent sound with it, but having a hard time finding any advice on setting the EQ properly - just wondering if any of you have used these and have any advice. I play a Fender modern-player jazz, mostly soul/blues. Thanks in advance.
