As such, GSP1101 enthusiasts if you would please provide me some guidance to get up and running quickly. I know where to get C63. My style is more in the jazz/rock idiom than hard rock or metal so please guide me towards some (preferably free) impulses which you've had some good luck with. To get started, I'd be looking for an off axis miced 4X12 for some Marshall crunch, something to pair with the bassman and/or deluxe amps to get more chime sans harshness and an improved dynamic response, and perhaps something which was miced at a distance. Looking for specific IRs, and the library/site they're associated with. Also, those who've come from an RP500 or lower Digitech device what features have you found incredible useful which were missing from the lower units? Thanks!
