You could look into a Josephson e22S or two. Some excellent microphonery in that little package. They take a brutal amount of SPL and are versatile enough to be pointed at pretty much anything you could want to record. They respond to transients wonderfully and are absolutely great for anything percussive, but also add a nice tonal quality to things like guitar amplifiers and stringed instruments as well.
I usually end up pulling one out no matter what kind of session I'm doing. This past weekend it handled a loud, low pitched Yamaha snare
drum (Tons of snap, accurate "ring", and GREAT hi-hat rejection with some careful placement). The week before that it was in front of an Oahu guitar amp for overdubs. During last night's preproduction session it was a spot mic for an acoustic guitar/vocal performance about 3 feet away and absolutely nailed it.
And, though you may have a fair amount of ribbons already, you might want to look into the newest offering from Crowley & Tripp, the "el Diablo" Mercenary Edition. It's the first mic built with Roswellite, the new indestructible (seriously) ribbon material invented and patented by my favorite Massachusetts Mad Scientists. Classic ribbon tone, but tough enough to live inside a kick drum and void of any phantom power and sagging issues previously associated with ribbon mics. It's got modern high output and plays nicely with any mic pre. It's also another one of those microphones that is capable of keeper tracks on any source. Do a search for the music video. You'll find it.
