For my personal needs, the Naked amps are too "naked" and "dry", as the name says. They are useful because you find perfect AMP/CAB matchings, but you have to spend some time adding effects and personalizing to your needs. The Live Gold pack is ready to rock. I haven't made much use of the Naked Amps, but I cannot stop playing with the Live Gold. The Naked Amps may be a good solution for professional recording studios, to substitute the tedious amp miking process.
Ohh, Sir! Thank you soo much for your advice!
