FMR Really Nice Compressor I use it for very mild compression and signal boost to get the maximum grind out of the Ampeg preamp Ampeg SVP-CL Crest CA6 1500 Watts bridged to 4 Ohms SWR Goliath SR 5,33 Ohms and 1000 Watts RMS Last year I started upgrading my rig, getting this together costed me a year time of saving and checking gear. I couldn't try everything here in the Netherlands, so I've searched this forum for opinions about every single item before buying. I got the cab last Saturday. The rig turned out hiss and hum-less, versatile and very very loud. You guys rock! Thanks a lot from a happy camper.
