I just got a new gig with a band called Mob Scene and we have some big gigs coming up including one venue that can seat 2000+. I've been mostly used to smaller venues and many times no soundman. I use a Sans Amp BDDI straight into my Ampeg B2 Combo and preamp out to an SWR Workingman's 10 with a 1x10 ext. cab. Now I've taken a lot of flak over the years about the "quality" of my rig and the power ratio vs. guitar stack power etc. so let me end all that right off....I have an intimate knowledge of my setup and can get whatever sound I want from it, in addition to being a "home stereo audiophile quality nut with high end equipment and a very discerning ear for quality" I have a long study history of acoustics and electronics and IMHO I can milk sounds from my rig that equal or rival rigs twice the price....soooo to the point. I have a gig at a large venue, with a large PA, a large crowd and an unknown soundman which I have no chance of making contact with, and little time to set up and no soundcheck! I'm considering compressors by several mfgr's and am interested in any advice on compressors or otherwise regarding the situation. I have mainly been involved in folk/jazz/bluegrass/improv-jam bands. Smaller venues, small crowds. The new band is 80's heavy melodic metal-originals+covers and we play loud. 2 guitars, drums, vocalist. Sincere thanks for any advice.
