Rack stuff is cool but it isn't for everyone. In a lot of ways rack gear is the same as heads or combos but there are some differences.
Rack gear can be tube, SS or modeling just like heads or combos. There are different tones and prices points for each type of amp just like heads or combos. Rack rigs have all the same components as heads or combos, just not in the same package. This gives you the ability to mix and match preamps, poweramp and whatever other off board gear you have.
The three biggest reasons that people go rack are flexability, midi control and stereo imaging. Racks are very flexable in a couple of ways. First you can mix and match pieces. If you want Mesa preamp tone and Marshall Power amp tone you can do that. Tube preamp and SS power section, you can do that. If you want more than the 3 channels typically available on some amps, you can do that. My Triaxis has 8 indicidual channels and my 2:90 has 8 seperate voicings. Doing the math I have 64 different channels/voices available before I save the first preset. Thats considerably more options than the average TSL offers.
Midi is scarey stuff to some folks but its really no big deal. The down side is you have to learn to use it, at least in its most basic form. The upside to midi is that you no longer have to do the pedal dance to change dramatically different settings on your amp. With the touch of one button I can change my preamp channel, two different effects processors and my poweramp voicing, or any combination of all those units settings. Having control over two amps, 15 effects, compression and EQ plus levels with the touch of one button makes for some very easy tone changes that would otherwise be very complicated to do by foot.
Stereo imaging isn't important to some people but I love it. Stereo chorus, reverb and delay can fill a room and for a one guitar player band it definately thickens up the sound.
The down sides are weight, expense and set-up time. A tube rack is heavy, period. The reason being is that you have so many power supplies and trannys. Solid state is lighter, modeling racks can be even lighter than that.
Every time you add a unit you add cost. As a rule a tube rack will cost more than a tube head, same goes for SS and modeling. Comparable amps cost more in rack form. Plus there is patch cords and the physical rack which isn't cheap either.
Set up time is sort of a variable, but unless you are slick racks can take a little longer to set up. I have breakout boxes with 7 pin connectors and Neutrix cables so my rig generally goes up quicker than a head/bottom/pedals rig but it's hard to beat a combo/no effects guy to the front of the stage.
Im only 20 minutes away Wixom. Feel free to contact me if you want to see how a proper rack works and sounds. You don't have to build a 12 space monster like I did and I'm sure I can help you get an inexpensive and toneful 4-6 space rack started.
Shoot, I have a spare 6 space rack, a BBE 362 and a Lexicon MPX 200 here I might be interested in moving. All rack stored here at the house and barely used.
