First time in the studio – tips?

I’ve been playing for more than twenty years, but in August I’ll be heading into the studio with a band for the first time and frankly, I’m terrified. We’ll be spending a weekend at the studio with a full-time sound guy and a producer.

Since I only own a JP6 and JPXI, I’ll of course be bringing those (the band’s other guitarist will probably bring a host of Les Pauls, strats and teles to round out the collection).

Do you have any tips for a first-time recorder? Things, you wish you’d have known the first time?
