Alright so SWR (it LOOKS like) is dropping their Workingman's series and replacing it with a slightly more powerful/sexier looking WorkingPro series. Obvious improvements (for heads) look to be a 450 watt head (to replace the current 4004) and a 750 watt head... not really replacing any Workingman's. In the heads there's this new "bass intensifier" circuit which allows you to select a frequency starting at 20Hz with a cutoff ranging from 80Hz to 200Hz that simultaneously increases volume and compresses those frequencies, as SWR says "making a 450 watt amp sound like a 700 watt amp and a 750 watt amp sound like a 1,000 watt amp." I'm a little skeptical. The heads are now rackmountable which is a huge plus to me. The cabinets however, seem to be the exact same as the Workingman's series, except now with a stamped chrome grill with a newer SWR logo. Has anyone had experience with this stuff? Does this "bass intensifier" actually work? Or does it just make you precieve it to be louder when in actuality it'll sound muddy when used on a stage or miked? Would a rig with the 450 watt head, 4x10, and 1x15 be worth replacing my 4004 head, 4x10 and 1x15 Workingman's stuff? I'm just curious and maybe other people are too.
