Perfect

Hi Phil. Yes that is the procedure I have now followed numerous times. However, the G75 still has significantly less range before dropping our than my G30, which just seems wrong.

I raised a support ticket about the G75, however the response doesn't even attempt to address the issue raised i.e. the G75 having worse range and more dropouts than the G30. Instead, for no readily apparent reason, it explains how to update the firmware on a G30...

Hi. How do you suggest tweaking the wireless channels please? Is this something other than running a scan and then selecting the channel with the least interference?

The G75 arrived today. I have just posted about it here: http://line6.com/support/topic/32322-considering-returning-g75/

I’ve been gigging with a Line 6 G30 for years and it has been reliable (except for PSU cables wearing) although on the odd occasion I have wished for something with more power/range when playing a venue where I can run around outside. Through these forums I was made aware of a good deal on the Line 6 Relay G75, described in glowing terms by Line 6 "Relay G70 and G75 deliver the best reliability and sound quality of any wireless system. A high-resolution pure digital radio captures your signal with four calibrated internal antennas, then immediately digitizes the RF signal. Super-high-resolution digital processing with triple RF filtering, fully optimized in-band rejection, and improved near-far response ensures clear channel performance." The G75 arrived today and the unboxing was favourable with metal construction, more options and a much bigger receiver than the plastic G30. Plugged in the G75 and the sound quality seems good with a nice clear signal into my Helix. I then started recording and took a wander with my guitar to test the reception, which unfortunately showed significant dropouts on playback. I then plugged in my G30 and walked the exact same route – no drop outs at all. Following this I have played with channel scanning (trying channels with both the least and the most signal bars in case I was getting it wrong) updated the firmware and taken numerous walks with both wireless systems. The result is still the same that the G75 has less range than the G30 and drops out where the G30 doesn’t. This is very disappointing and appears to be a downgrade in a key performance area for a wireless system. I thought the newer/higher end systems were supposed to have a 300 foot range compared to the 100 foot "line of sight" range of the G30… So right now I’m pondering whether to try and return the G75 as I want more range at gigs, not less. Any thoughts or suggestions please? Is there something that I’m missing/doing wrong?

OK - despite owning a perfectly serviceable G30 I've just ordered the G75 (only the best for my Helix) so it's your fault if it doesn't work :)

Have you given it a try yet? If so, any sign of the infamous dropouts?

Typical - I don't read the forum for a week or two and something interesting like this comes up! :) Have just sent an email.

When I first tried the Helix in a shop I was also underwhelmed with the sound, although impressed by the build quality and interface. However I took a punt and bought one. Got home, connected my guitar and a good set of monitor headphones and before long I was converted. Also now using it for gigs through a power amp and my guitar cabs.

If you aren't worried about the cost then go for it. I think you will find that the Helix sounds significantly better and you will end up using it all the time. Also, the learning curve is negligible (certainly easier than the HD500) and you will probably be up and running before you know it.

Welcome to one of the great guitar truths: If you have a problem with your wireless system, at least 90% of the time it will be down to one of the wires :-)

The Helix made it through tonight's gig with no apparent problems so hopefully the previous loss of sound issue will just be one of those freak, one off events.

I'm gigging with the Helix again tonight - fingers crossed! :-)

Regarding possible issues with the power supply it's the first time I've used the Helix at this particular venue, although I have played there quite a few times previously using other gear with no issues. However, I can believe that some places are worse than others when it comes to the quality of the mains power as back when I used to gig a midi rack system with a Marshall 9200 power amp there was one venue (now closed) where on several occasions it blew fuses, which never happened at all anywhere else.

Mid way through a song in the second set tonight my guitar suddenly cut out. I wasn't even touching the Helix at the time. I tried changing patches (nothing doing) and quickly checked the cables (all still connected) and everything looked fine and the power amp was still on. Turned the Helix off and back on, it rebooted and then sound magically returned and it worked for the rest of the gig. I really hope this sort of wobble doesn't happen again!
