Line 6Relay G30 Wireless Guitar System

Will the g30 work in usa and does it do good with a bottom b bass string ?

I'm looking at using this with an acoustic electric bass. I see lots of comments about how great it makes guitars sound, but nothing about a bass.

Does the transmitter make any pop sound when you turn ON or OFF the power switch? This is important since it doesn't have a mute button like the G50.

The lekato 2.4 ghz version works pretty good - will this boss be better for $150 more ?
