HD100 MkII? Which output on the amp is it plugged into?

"... wonder if the acoustic 700 brain would load into the electric?"--- No, it won't. That too would brick it. Yes ibowze,... using the interface device is the best bet.

Spider IV 1508?

Which Spider IV amp?

Kevin Cadogan of Third Eye Blind, Trevor Rabin of Yes (et al), Shawn Phillips, Ted Leonard of Spock's Beard, David Freiberg of Starship, Robert Sarzo of Queensryche, Carlos Rios (Chick Corea and Stevie Nicks), Oz Noy, Stevic McKay of Twelve Foot Ninja, and others,... I know they are all Variax users, because I've had the pleasure of servicing their guitars. There are some photos on the web of James Taylor with a 900 Acoustic. My lab mate got to service that one,... and probably that electric in the photo here, since he does most the early Variax guitars.

No there isn't. Cutting any trace would send wrong data to the chip. All FX would be full on, full off or a jumble. The digital chips in general have expectations of of data. Messing with that confuses the program, and gibberish comes out. Just knowing the pin-outs isn't enough. I used to do digital mod updates when I was servicing M20 ADAT's back when I was in repair at Alesis. It's touchy surface mount stuff, not to be taken lightly or messed with without the proper tools. If it were op-amp circuits in an all analog amp, that would be a different story. You always get a DL4, run it into the Spider IV 30, running the amp totally clean of FX, accept for the DL4. And you would have better control-ability of your FX's.

"... it acts as if I'm turning the chorus knob as well. The Master Volume knob controls both the vol and the Chorus"--- That sounds like a short somewhere. That should be taken to an authorized service center. They will have access to service info and me.

"Is it actually considered a 700 by Line 6?"--- No, it's a 900. Don't know why a sticker would be 700. It was a limited run. These were before my time here. Though I and another tech here still work on them. "Just a promotional version given to artists and those within the industry?"--- Promotional? Don't know. Artists and those within the industry? Sort of. Some artists and a few others. "Have you ever seen on in Sunburst finish in person?"--- Once, maybe twice,... it was some time ago.

Yes, what cruisinon2 said,... it may have to come back to me for some TLC.

The VDI interface device is used to connect the guitar to Workbench or Workbench HD. The 500X had the "go-between" Flash update capabilities. Not certain about Workbench or Workbench HD connectivity. Early on the 500 didn't have that, the "go-between" connecting, if I recall was a later update to the 500 firmware to allow Flash update of guitars. Don't know about connecting to Workbench or Workbench HD thru a 500. Also, firmware up to and including Flash v1.90 on the JTV, and v3.25 for Variax Acoustic will run on Workbench. Variax Acoustic won't run on Workbench HD, that is for Firmware v2.00 or higher, and for JTV, Standard and Shuriken.

The firmware is the same in both.

"One was supposed to have potentially been owned by James Taylor himself at one point in time"--- Last I heard, he still had it. Talked about it briefly with Tavis Smiley once on his show. The 900 is a fancier 700. The 900 has more elaborate inlay and edge trim, gold-ish tuning machines, slightly different and nicer finish. The electronics are the same as the 700 Acoustic. https://www.google.com/search?q=line+6+variax+acoustic+900&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwizlcP64YHVAhVK7mMKHen6BTsQsAQIRQ&biw=1405&bih=853#imgrc=_ First pic in the array is a 900 Acoustic.

"Are you using AES 110 digital rated runs under 50'?"--- Good question. Can't use 50-Ohm mic cable, it the wrong impedance. Have to use the AES/EBU, 110-Ohm, L6 Link cable, under 50-feet or you will have signal problems. Acoustical problems are typically from what's called "air leak distortions", typically when a unit is re-assembled after servicing. Where gaskets and grommets are not all there and/or the hardware is not tightened down to the correct torque.

http://line6.com/software/index.html ... find Variax Acoustic, then Variax Workbench (not Workbench HD). Select your OS, then "Go".

No way to go direct. No power amp within that can drive speakers. JM4 is instrument output level. can't drive speakers on it own. JM4 --> power amp with instrument or guitar input --> speaker JM4 --> Active Speaker with an already amp in it. ... would be the options here.

Nothing in the Downloads page for Workbench for the bass guitars beyond Flash and Monkey.

Could be a loose potentiometer retainer nut under the knob. Loose pot affects the chassis ground. Make certain the retainer nut is snug (not tight, but snug). Do not spray contact cleaner directly into it. http://line6.com/support/page/kb/_/general-faq/cleaning-pots-and-faders-r816

The older Variax's like the Variax 700 works with Workbench, but not Workbench-HD. Older Variax patches are not able to port over to the Workbench-HD format. Have to use the earlier Workbench with a 700.

Orville Gibson, Adolph Rickerbacker, Leo Fender and Harold Rhodes (whom I knew),... ... all long since passed on. Yeah, name it after a dead guy, gives it a sense of music technology history appreciation,... like Stradivarius.

First,... this topic should probably be moved to the "Spider Valve" link, as this is ahout HD MkII. So I would think this is an HD-100 MkII. Second, never turn on a valve amp without the correct speaker load, or dummy load on the outputs. Without knowing what these two amps are in particular, it would be impossible to know. For instance, you can't run a speaker output from one amp to the input of another amp, it will all short out. Check with my mate Mark Wright at Mark Wright Music in Northampton. He used to be a repair tech for Line 6 Rugby, when we had a Line 6 in Rugby.

For factory default, re-Flash it with the latest v2.22 program.

Gear Box or POD Farm. Should've come with the UX2.

"Could the gubbins of a Yamaha Variax be slotted into the 700?"--- Too many hardware incompatibilities. Unless you have intimate knowledge about these two guitars, good at guitar custom work and a lot of time on your hands,... then I would advise against it. "I just wish line 6 (or Yamaha) would make a new acoustic Variax"--- submit to Idea Scale.

Is the trem bar screwed down snuggly? A loose trem bar can rattle and be noisy. Those trem bars are internally threaded, screwing them down minimizes this.

"I have had a jt variax since launch day in.... 08?"--- Close. Launch date was around October 2010. The build date was a little earlier than that. But you're close.
