M9 users are you having this problem with Bypass ??

[Andre357]

This thread is going on in effects :

http://www.thegearpage.net/board/sho...d.php?t=629556


Can someone read this post below ( so you dont have to read the whole thread if you dont want ) - experiment with your setup and let me know if i need service or if this is sytematic in general ? Thanks

Guitar > M9 > amp. I disengaged all effects and go into the set up menu and switch between DSP and True bypass. I hear no difference. I am using a short cable going from the M9 to the amp.

Sorry to be redundant, could you go into the set up menu and go to the screen that says Gate and be sure the threshold is set to OFF.


" Rich - I just tried my m9 exactley as you described above. Guitar - m9 - short cord ( maybe two feet )

gate threshold if is most definitely Off

There is quite an audible difference between true bypass and DSP with no effects engaged. When in True Bypass mode and I kick in an effect the drop in audio is such that true bypass mode is rendered useless.

Did some of these get out with a bad buffer or a defect ? Can other M9 owners try what's described above and chime in ??

perhaps mine and audio mikes need service ? Please let us know.

PS love the M9 and I'm using it in DSP mode with a clean boost after to compensate for the overall volume loss....but there is most certainley a problem...at some point I'll want to use true bypass mode and right now I can't.

Thanks man ..."

Thanks everybody

i have the m9 and tried it , i have no pb with volume using true bypass or dsp bypass...

Thanks very much.

So when all effects are off and you switch back from true bypass to DSP there is no volume difference ?

Anyone else ??


Perhaps mine needs service - but I'm wondering if others have this problem.

Maybe thats a good thing it's isolated. I just want to confirm it's a fixable problem.

I have a line 6 authorized repair shop just about three miles away that turns around stuff in just days so this is not the end of the world.

Thanks in advance for anyone else that will try the expirement described above in my original post...

Mine has the very slightest difference when I switch between true bypass and DSP - it's trivial, and I'm not sure if it's a volume or tone thing. I do notice some volume changes with certain effects, but that in my mind is a function of the model, not the unit. I've noticed very similar stuff with analog pedals so it isn't really an issue for me.

Thanks - Mine is a serious volume loss on every effect when in true bypass. Like taking a volume knob from 10 to 6 ( or even 5 )...

It renders true bypass usless, and makes it so you need to boost your signal when in DSP mode to compensate for the vol/tone loss in general.

Hopefully Rich will chime in. If i hear it's an isolated issue or a software glitch that would be good news to me and I'll get it fixed...

Sometimes shit happens when your an early adopter...so it's not the end of the world if i need to get it fixed...

Maybe others will chime in

mine had this problem intermittent, depending on pressure to the input and output jacks. got it exchanged, and haven't noticed it since

Thanks - so you had a big volume difference between True Bypass and DSP or when engaging effects in True Bypass mode ??


Maybe I'll fool around with the jacks tonight

[dramaticrunner]

both, there was a large volume drop whenever the signal was going through the dsp, either dsp bypass, or with an effect on.

believe it or not thats good news to me ( at least I know it's a fixable problem ).


I wish I noticed it before my return time expired ( I've had it over 45 days )...

But I'll take it to be serviced ( authorized very good repair center just a few miles away )

[dramaticrunner]

i feel you, because the m9 is integral to my set up now! btw, a repair center is most likely going to take your m9, send it back to line 6, have line 6 send them a new one, and then send it back to you. if i were you, i'd just try to get a warranty replacement directly from line 6

Thanks man. I've used this place for years ( it's right across the street from Berklee college in Boston )....

I've had Line 6 stuff fixed there and Boss stuff ( authorized repair for both ) plus amp, guitars etc.

Both times with boss and line 6 they fixed it in house within a couple of days....

They have good people there and a good track record with me so I'll give them a shot first.

I'll tell them if you need to send it out to call me first though...

Thanks again !

There are a few threads on output dropping on the Line 6 forum but none of the people from Line 6 are responding for some reason. One popped in and asked a question but quickly disappeared.

Yeah - one of those people is me ( andy xxx )....

I wish they just would respond and say " yes, you should get it fixed we had a problem in QC or at the factory "

Adults realize these things happen especially when your an early adopter of new technology ...

If this is a widespread problem al ot of folks may not realize it if they are in DSP mode all the time ( like I was for a while )...

Overall I lOVE the unit, aside from this problem it's sounds fantastic... So I'm eager to get it fixed and back on my board.

Or maybe its more widespread than they care to admit


I remember Eventide had that noise problem when the Timefactor first came out....

But they were upfront and said " we screwed up , please send it in for service and sheilding "

Not saying thats the case here...I just remember that for some reason..

You are right about new tech causing headaches - if I remember correctly the Nova Systems had problems early on, I remember a batch of Mac laptops that had battery issues and the recent Malekko delay had some issues as well. Hell, even my Toyota truck has had a recall. I also agree with you that the nature of this issue sounds fixable. Could be something as stupid as intermittents in the jacks.

It's frustrating I know, but these are complex machines and six sigma QC isn't always the standard. From my perspective, the way a company deals with issues such as these has a great deal of bearing as to wether or not they will get my future business.
