hi. i sent my r4 into edirol today, and figured this was worth mentioning:
it was confirmed for me that *every* one of the units within that range of serial numbers has the issue on input #4, so plan accordingly.
they pay shipping both ways, UPS two-day to bellingham WA. i was told at most it would take 14 days, but when pressed, the tech told me they turn everything around within 3 days of receiving... the rest is up to shipping lag times.
SO... anyone else taking their r4 to ACLfest? ship it tomorrow and you're good to go.
how many folks on this board have r4 units anyway? just curious. ted at edirol told me there were less than 1000 in circulation.
