Thanks for your reply. You have convinced me it is indeed worth the upgrade. I had so much fun with the SPIV head that the SPV seemed like the most obvious replacement. I don't understand why some guitar players complain so much about these amps, I have found them to be so versatile for use in gigs, recordings, classes, jamming, or just to get some inspiration rolling from a certain sound. Love it. Spider V to be added to the family soon, thanks for the advice.
