What do you guys reccomend for wireless?

So you never move further than 68 cm away from your cab? :err:

And yes, A/D conversion introduces a little delay by design...
But 4 ms shouldn't be that bad, again that's like moving a little more than a meter away from your amp ;)

Yes, I understand it equates to around a meter from the cab. However, I can still slightly feel the latency when playing very fast runs, arpeggios, etc. at fast tempos >170 bpm. For most rhythms/riffs and stuff it doesn't really bother me. Again, the signal/sound quality is awesome on the Line 6.

I'm just curious if the analog systems introduce latency like that as well, and if not, what are the best options for analog/UHF etc. I've never dealt with wireless systems before because of the sound quality and spinal tap horror stories Ive heard, and I also couldn't bring myself to part from cable. But now, for playing live, it feels like a necessity. Especially when you are trying to put on a show and running around with 2-4 other people on stage. I'm sick of trying to tap dance around cables and attempting to choreograph stage moves to avoid crossing the streams.

I just set up my singer's Sennheiser ew 100 wireless mic at rehearsal, and it sounded great, and I really couldn't detect latency. But then again, that's vocals, not super fast shred guitar. So that's why I'm looking for this kind of feedback. I'm willing to sacrifice some dynamic range and frequency response for faster attack.
