Hi there,

I've a technical question about the hd500.  I've looked all over the line 6 forums, as well as the internet in general and found nothing relating to my question.  I hope you can help.

I will describe the problem in detail shortly.  Could I please ask for only helpful and constructive answers relating to the way I have chosen to use the pod, and not knee-jerk responses telling me to simply not use it this way: I'm new to the line 6 forum and sure it's a great place, but there are forums where many of the replies are less than helpful and I hope we can move forward with this issue in the most pleasant and mutually constructive manner possible.  Thanks!  One last thing: I am a professional musician, gigging and touring regularly.  I am using the pod in a live environment, and have tried a variety of set-ups.  The one i have settled on is the one that best suits my needs.

The pod offers me a huge amount of flexibiltiy in terms of reproducing the wide range of sounds recorded on the album which we are currently touring.  However it is my own personal preference to build those sounds around a real amp and cab when going for driven sounds - which make up around 80% of my tones in live use.  I like to drive both the power amp and the speakers hard.  We are mic'ing up the guitar cabs and running through the PA in all our shows.

The routing flexibility of the pod is an incredible asset and allows me to use it in a way whch might not have been envisaged by the designers:  I run my guitar into the guitar input and set channel A input to guitar.  i then run through any overdrives and distortions i might like to use, and wah/phaser if applicable.  I then put an fx loop block in line with send at 100% and return at 0%.  I also set the mixer A fader to mute.

I then take a feed from the physical fx send output of the hd500 to my guitar amp, which then goes to the cab, which is then mic'd up.

This would normally go straight to the FOH mixing desk, but I 'steal' the feed and take it back into the pod, via the mic input.

I set channel B input to 'mic' and then I run a compressor, flange, chorus if applicable and any delays and reverbs i need.  I set the mixer channel B fader as applicable per the song in our set (I work around 0) and sent the output to the mixing desk, FOH.

This set-up works perfectly for me and gives me the same great organic overdrive tones that we recorded on the album, along with studio quality compression, delay and reverbs after any distortion stages. However there appears to be a bug in the HD500 which causes a feedback loop when the HD500 is put in tuner mode in this set up.

It appears that the mic input - coming in to channel B is somehow routed to the fx send.  Thus creating a feedbalk loop where the mic on the guitar cab goes directly back into the amp.  My workaround at the moment is simply to use a standalone tuner pedal, but would be nice if i could be 100% self-contained with the pod.

Please could somebody from line 6 advise if this behaviour is intentional?  If you need further details or need me to upload some patches to show you exactly how i have it rigged, don't hesitate to ask.

finally thanks to all for surviving the long post.  I'd be interested to ehar from any others who use the pod in the same or similar way. It is an incredible move forward for me and having effects in the pod both pre and post the real amp, cab, mic, means no more tap dancing too.

Many thanks
