Okay my vote goes to these two:
--Analog Man BiComprossor-- A boutique clone of a Dan Armstrong Orange Squeezer feeding a Ross Compressor (the purple one made famous by Trey Anastasio from Phish. This is the shit!!! You can choose either or both in series, which is a killer tone to my personal ears. Great build quality, good value, and sturdy as hell. Boffo!!
--Demeter Compulator-- a fantastic single stage emulation of the 1176. Not too drastic, but very versatile and forgiving. Especially effective on acoustic pickups!! Also great on Rickenbackers! Good LED. Quiet and extremely well built. Only bummer is the mini-plug power adapter connector. WHY?
I have the following:
MXR DynaComp--two originals that sounded completely different, and one reissue that stunk in comparison
Rockman Compressor/Line Driver-- half-rack unit that is perfect for the classic Def Leppard clean tone. AC power is a plus. Good EQ options. Interfaces with distortions very well. Lots of connection options. And damn quiet.
Ross Compressor-- holding on to this Purple baby for vintage value. But I must admit the AnalogMan clone does the same thing, only better.
Dan Armstrong Orange Squeezer-- I have three units of this, and they all are of different vintage, and sound much different. You want "Sultans of Swing?" Plug a Strat set on the treble/middle notch pickup position (second from treble on a fiveway switch) thru this into a Fender Deluxe amp and crank it up to about 8.
Toadworks Mr. Squeazy-- very versatile, and also very quiet. A good choice for all around use, but somehow it was not magic for me.
DOD vintage late 70's compressor-- a non-magical DynaComp that actually seemed to work very well on bass. Go figure.
So what are your opinions?
