I'm very impressed with the formula preamp. my only gripe is that it's slightly noisy. not unmanageable, but it could have a lower noise floor.
The clean is impeccable. lead 1 gives a nice mark series lead sound- good for santana-ish stuff. neck pickup and roll off the tone and you're there. you can also get a nice stratty blues breakup thing here. lead 2 works very well for a standard rock sound. there's no modern sounds in here, but it does have a good amount of gain- it's just voiced more along the regular rock side of things. all this versatility in one rackspace is a huge plus. I'm running it with a mesa 5050 stereo poweramp and a pair of CAA 1x12 cubes. I have the formula and 5050 in a 3space shock rack so I can just take that as a head if I want.
I also have an 8space effect rack that I can hook up to the "head"rack. It has my wireless, an interface for connecting everything, an RJM effect gizmo, a pedal tray with a tuner, phase 90, compressor and chorus (and pedal power 2 and rjm line mixer), lexicon mpx1 for reverb and delay, and a tech21 rpm preamp for my acoustic. it's all controlled with a pedalboard that has an rjm mastermind midi pedal, teese picture wah and visual sound volume pedal, and a breakout box that sends power, midi and audio from the rack interface. it's a pretty streamlined rig with a good bit of versatility, and it can be setup in less than 3 minutes!
