In the next few days I'm going to buy a Peavey 6505 head. Furthermore I have the following Amp Sims: Guitar Rig 4, Amplitube 2 & Metal, Softube Metal Amp Room, Ampeg SVX, Waves GTR and I have also a Sansamp PSA-1 hardware (not the PSA-1.1!!!). With all the other stuff in mind, do you think it's worth keeping the Sansamp?
