Obvious, sadly - It's not just that the feedback is more present in the latter, the former is just plain warmer, creamier. Dunno why - but it is. I still like the verbs and delays on my PCM-70 more than those on the AXE too. I don't use 'em much because I use the PCM-70 for more radical stuff most of the time (their fantastic flanged-multitapped 'psycho echoes' patch particularly). If there were 2 independently controllable fx loops, I'd probably never use the Axe's delays, I'd just throw another (heavy and fragile) PCM-70, or a 2290 in the rack. It is odd that this old digital gear sounds warmer to me - I presume it's not the conversion technology - it could be the preamp in the input section, or it could be Lexicon's (and TC's) proprietary algorithms, but I wish Cliff would suddenly become obsessed with MIMICing effects (he probably will, someday), and we could get all the ultra-creamy goodness of m PCM-70 into my Axe II.
