If you're talking pedal format, I use the Aguilar Tonehammer. Super clean DI with fairly powerful tone shaping capabilites. It has the Aguilar AGS circuit that's used on the Aggie TH heads, and a nice single band sweepable mid control. You can go from clean to a warm drive sound with a bit of hair.
A nice feature that I've used for recording is to go pre-EQ with the XLR out for a dry signal, and simultaneously go affected out the 1/4" out. Blend to taste on the console. Works very nicely!
Another nice feature is that you can also use it as part of a live rig with a poweramp and cab.
