Obviously Yamaha decided there wasn't enough interest to continue the Variax!

Spray some contact cleaner in there first. After that I'm guessing there'll be ribbon cables inside. Again if there are clean them with contact cleaner and reseat.

There is no physical hard drive in an M20D. Steer clear!!

It's late, but maybe this'll help.

Recently went on a guitar set up course with Crimson guitars. Fitted a new Parklane roasted maple neck to my JTV 69, did a complete set up and set the intonation no problem. You do have to be careful not to pull on those piezo wires though! However I would say you do have to release string tension every time you make an adjustment, but you'd do that with any regular guitar.

Just got one sent to the UK from Thomann in Germany.

Open it up and clean all the ribbon cables. The connections oxidise.

A little bit late to this party but.... If you're happy opening the M20 up then do so. Remove the ribbon connectors and clean them with a good contact cleaner, let them dry and re seat them. There is a ground that can also get oxidised. On ours I've actual soldered a wire to it and grounded it to the chassis. A 3rd problem is how close the boards are to the case, so whilst it's apart line the case with a non conductive material. Regular maintenance of this type is the ONLY way to avoid the problems being described here. This whole range was a great idea but I fear that since Yamaha got involved most of the really innovative stuff has been put out to graze. I have a TF1 and there's a load of stuff on there that for me shows why they went after Line 6.

I believe there was an issue with electronic interference compatibility rules in Germany! It was withdrawn whilst the problem was sorted, but as seems to be the way with Line 6 since Yamaha took over, nothing seems to get fixed or updated anymore.

The G30 is a great little unit for home use. Avoid the G10, it was never great and is absolute garbage now!

If you're in the UK and having this problem, I can usually sort this out for you. I've been hiring these desks out since they were first released. We only have 2 left now as we moved to the Yamaha TF1 as soon as they came out due to the regular maintenance required to prevent this issue. I only keep the ones I have because a couple of regular clients won't change to the TFs, physical size issue!! That said they aren't hiring at the moment here anyways so I might just off load them!! If you need help or advice pm me.

Where you based?

I still use my Mk 2, though mainly for home recording now. Using a Spider Valve 2 for live work until I get the amp modelling sorted to my liking on my TC Helicon Voicelive 3 extreme. Then my rig will be on the floor in a pedalboard and my days of lugging a heavy amp around are done!!! I also get vocal harmony, talk box effects etc with little hassle. Feel Line 6 let their loyal customers down since Yamaha took over and I think credibility is going to be an issue for them going forward. Most dealers in the UK see them as home use products, unless you're going for the high price items like Helix etc.

It's finished in the UK according to Andertons. They've got the last stocks here and they're dirt cheap!

Mne defaults to whatever the last preset used was. Do you have an FBV control board?
