Not sure if I'm going to keep it. Actually, many of the presets sound pretty good, though I don't have a use for a lot of them. So far, I've only found one that's really noisy, which is one of the "clean" tones (?). I'm going to do some serious patch editing, although there are a few useful ones from the factory. Their version of Billy Sheehan's tone is probably as close as you can get without using Billy's equipment. A couple of the amp sims sound pretty good as well. I don't think the flanger/phaser/chorus stuff is all that useful to me, but they sound reasonably good. They tend to put some echo or reverb on a lot of the sounds, which I think is pretty useless on bass. I'm going to see if I can make up some EQ/compression/overdrive patches that will be workable for me. If not, back it goes. I should probably just buy a SansAmp (three times the money), but the 506II has a cool mute/tuner function, as well as a headphone output. So, we'll see.
