OHMIGOSHTHISTHINGISFREAKINGAWESOME!!!!!!!! The tone I've been seeking for years is now MINE, ALL MINE!!! MUHAHAHAHAHAAAAA! Run, don't walk, to your phone and grab one of these puppies before Dave comes to his senses and starts charging what it's worth! (No connection with Avatar, just a customer who's happier than the proverbial pig in chit.) I got the Delta LF version... I play 5 strings, and wanted the extra low end. BTW, I'm driving the cab with a Tube Works head pulled out of my faithful 1x15 combo that's served me well for years. 260 watts into 4 ohms, or something like that. (These amps aren't well known, but they're still made... Genz Benz bought TW... info is on the Genz Benz website.) I'm playing Carvin active basses and have a Presonus compressor. I was (and still am, I guess) considering selling the Tube Works combo and buying an SWR head (I like the SWR tone), but based on that first session yesterday I don't think I need a new amp. It sounds darned good just as it is. Dave mentioned when I ordered it that he likes the horn control turned up just a bit... if "off" is at 7 o'clock, he likes it at 9 o'clock. It does indeed sound great that way.
