Check the Line 6 Downloads page, make certain the versions of Monkey and Workbench HD are

current and match up with your Windows OS.

Something has to be in there, says it's connected to a 59, and the slots are labeled,...

Are you using the correct interface device, correctly?

Dialing in and being more spot on with string tuning and intonation also helps.

Sounds like dual tone effect. That's when you hear the standard tuning coming off the strings, and the alternate tuning coming out of the amp.

Turning up the amp a bit will minimize it, as would using headphones, depending on where you are and your set-up.

Knob top,... very small dabs of Krazy glue on the knob rim, put the top back on, let it an hour before putting the knob back on the shaft.

Anytime.

Ah, right, sorry. I see you are outside the USA. See if one of these can get you one.

I see a VDI--> RJ45 cable, but I don't see an Interface device.

For the 89F,

30-51-0689 for Hi-E/Lo-E

30-51-0690 for A/B

30-51-0691 for D/G

For all JTV, Shuriken and Standards, 11-00-0010.

"I didn't see more than one kind so I figured all the piezo saddles were the same!",... not for the 89F.

They are paired off,... Hi-E/Lo-E, A/B, D/G. Have to get the correct ones and insert in the correct paired order,

or it won't sound right.

Take it to an authorized service center, so they can go through it all correctly.

Heater fuse, old tubes bringing down the heater fuse, and about four other things it could be, none of which is going to be a self repair.

Tubes should be changed out once every 18 months on average, depending on use.

Please keep your fingers out of the insides of these, the shock hazard is too great.

It lights up, so it sounds like the processor board is working.

Still available. Check with your local authorized service center.

String tension to piezo is key to the piezo having good mechanical to electric transfer. Optimum string set gauges are 10's and 11's.

After string tension and piezos, the rest is DSP. Workbench HD is good for adjusting things where you want it.

Try eBay for a unit being sold for parts only.

Care fully pull up the knobs, make certain the retainer nuts holding the potentiometers are snug and tight.

If that doesn't work, it will need to be checked out by a Line 6 authorized service tech.

Exactly. Those too.

Thank you cruisinon2.

Keep away from florescent lights.

Thank you silverhead.

And if I recall correctly,... Custom 1, toggle-1, Alt Tune on Model, gives you the model for the 69.

Yes, there is a model for the 69 in the 69 (or 59, or 89/89F). I almost never use it except test purposes

once every blue moon.

And you can always go into Workbench HD, and modify it even further.

That's good to know, one less thing to think about.

Going through an amp, yes. A different amp with different set of speakers in it might emphasize a

different set of resonant harmonics. That's where some filtering comes in handy.

-Dual Tone Effect, where you are hearing the strings in standard tuning and the alternate tuning out the amp, together.

Typical with 1/2 step down as it more dissonant to begin with.

-500X tuning might not be as dialed-in as it could be, making Dual Tone Effect worse.

-Variax string tuning has to be tuned very close and dialed-in for custom or Alt Tune to sound alright when doing a 1/2 step difference.

So long as the cabinets are 8-Ohms each. Less than that and there will be a problem.

Sure, AlNiCo is fine.

Program for the heads are different, and slight difference in other places to accommodate different 3rd party cabinets.

Modeling program for the heads is designed for that, program for the combos are not. Been that way since Spider III and Spider Valve.

As I've said before, these are not all analog tube amps, so you can't get away with doing the kinds of things we used to

do in the all analog tube amp days (circa early 1970's).

Had this chat with a audio test analyst guy here, as we both used to work at JBL (or JBL/UREI in my case). Was picking

his brain a while back for my prior comment, as he was dealing with some Neodymium speaker testing that week. Hence

my prior comment.
