Jtm30 ET-65 pairing?

Hi, guys, appreciate your time in answering this.  Just picked up a nice jtm-30 which is open-backed, in which I have already put an et-65, which sounds great. Here's my question: I have the 23" Mesa Transatlantic cab, which is open back also, and in trying to find my answer in the forum, have gotten confused.  I only use the clean channel, with an OCD and an ep booster.  I'd like deeper lows in the mesa cab, with rich, musical mids and highs to compliment the ET-65.  I want to stay away from buzzy overdrive, I don't use a lot of gain, more of a Robben Ford thick, singing tone, lots of sustain.  What would you suggest?

 

Thanks so much!

Mike
