So i've been having some interesting experiences recently. I haven't used the Sansamp before, but my guitarist/singer who is a professional engineer/recording and live sound will not stop raving about the Sansamps that he's recorded with. Granted I haven't really played any "Harder" rock in a while, so i don't really know. He likes overdriven sounds a lot too, and I tend to steer away from them, but it might be nice to have the versatility of having the drive available to me. I hear it's a great pre, I just haven't played one before. If I can get this to work well, it might replace the Ashdown ABM500 (which i'm not sure if I'm in love with the sound.) I can't really tell if it's the ABM500 or if it's the NV610 that isn't giving me what I want out of the sound. Maybe it's the room. Maybe it's the lack of tweeter or low low low end frequency response. I tend to use the Low B a lot now (which is actually tuned to B flat) Continuing with this rant, I played with my Aguilar Rig *(AKA THE MONSTER DB680+CA9+S810) this weekend, and it was golden. Pure magic with the BN5, no doubt. Unfortunately it's in my big touring rig and I can't cary that with me all the time. So my questions go as follows: 1.) Do you think that the Sansamp RBI + Iamp800 + NV610 will be a great combination for rock. If so, or if not, why? What have your experiences been with these items. I'd especially like to hear peopel who have run them together. 2.) ABM500 EVO II not giving me exactly what i want, should I let it go? Or should it give it some more time for me to like it. If I should let it go, what should replace it if anything at all? 3.) Do you see there being advantages/disadvantages with the ABM500 EVO II vs. the Iamp800 with the Sansamp. Will that 800 vs 500 watts make an aduible difference? (WHY NOT TRY THEM OUT?)...the NV610 ABM500 rig is in LA with my band. I'm up near SF about 5 hours difference.
