Got this rig a couple of weeks ago (201S/PLX1602/HT322) and have been chomping at the bit to give it a good live gig shakeout. The club we played in is probably medium sized (approx. a little over 100 person capacity) with great acoustics. I have a StingRay 5 that I've played for about 3 years now. I used the passive input on the preamp and had the SR5's volume and PLX fully cranked (bridged with clip limiter on & filters off) and used the 201S volume control to set the sound level. I use the single coil position on the pickup selector 95% of the time and I had some midrange & treble cut and a little bit of bass boost on my bass. The 201S was flat w/all the switches out and just a little bit of bass cut (to control boominess--the dem bass control operates at a higher range (60Hz) than the SR5 does (40Hz)). I usually play with a fairly light touch (which lets me control emphasis/dynamics a bit more). I started out with the 201S's volume at 12:00 and the sound was very clear, punchy, smooth, with tons of low-end solidity. I could hear myself really well in the mix and it sounded so good, the other people in the band kept telling me to turn it up. I ended up with the volume at about 1:30 and I never really dug into the strings or stuff would have been falling off shelves at the bar, but when I punched it a little, there was some of that really smooth type compression in the sound you get from a good tube amp. The lead guitarist and his wife both commented on how good the bass sounded. I believe that I played better than usual, partly because I could clearly hear what I was playing and partly because I was inspired by the way it sounded.
