It works, it's overkill. Getting up into the high range frequency bands,... not necessarily a good thing if you go too high beyond the data rate frequency of the FBV. So use a cable that stays withing that range. Having the highest bandwidth cable isn't always a good thing. Frequency of the application is crucial. A customer had trouble with a rack effect with his FBV a couple months back,... he was using CAT6. Once I switched it to CAT5, it was fine.

Just be aware that the innards in the above photo are not JTV innards, though it is Line 6 Variax electronics.

Piezos for the old version are still available. Check with Full Compass. You're not deaf, it's something that's subtle, some hear it and some don't. I hear it, but then, I've worked on 1,500 of these.

EH version of the tubes is best bet. EH owns the Sovtek factory. EH version goes through extra testing, and there's more consistency in the performance. When was the last time the tubes were changed out? If you gig that much (plus rehearse), then the tubes ought to be changed out every 12-18 months. Weekend rock warriors 18-20 months, while for the occasional bedroom rock star, change them out every 20-24 months should suffice. Unless one goes sooner. Have seen some tubes last two weeks, while others I've seen last five years. Depends on the tube, the amp and how hard the tube is driven.

Yeah, I'm familiar with their work, they're pretty good.

Calabasas, CA. Did the mod for Oz and others as a favor for high profile Line 6 endorsers and the boss. The mods for Oz was done by guitar luthier Touch Singleton, and I just did some tweaks to the electronics. Mods are not something I normally do, as we do not have a custom shop here. And I have a steady stream of regular service repairs. I do have a colleague in Northampton, UK, who used to be my opposite number over there, when Line 6 had location there. He has his own shop, Mark Wright Music, and still services Line 6 gear, including guitars.

Correct. Good idea for them to check with the user manual first before haphazardly plugging things in. No biasing needed for the Spider IV 150, just the Spider Valve series (being tubes and all).

Happy hunting. :)

I guess with an SV 212, there's a bit more lee-way on that. Those boards come in two varieties, combo and head. Just one thing, use the specified 5881WXT power tubes,... have to be matched pairs. And of course, use the correct bias voltage, should be in the Knowledge Base. Even with the power off and main unplugged, you can still get a couple hundred Volt zap from a capacitor discharge, if you touch the wrong thing. Hurts like hell, so be careful, got accustom to having you here on the Forum. Wouldn't want you shocked by a tube amp, so stay safe.

See pages 4-5 in the Pilot's Handbook. http://line6.com/support/manuals/spideriv150 Use it as it was meant to be used. Keeping your gear off of my repair bench. Rock On!

Do not use a combo chassis as a head. The boards are programmed for the specific amps. The 150 combo is not programmed to act like a 150 head. That sort of thing would explain some of the Spider IV's that come across my bench,... dead program boards and blown amp chips. That explains a lot. Do not do that.

It's active electronics, so there are subtleties of the circuitry that have to be careful of. Turning Oz Noy's customized two pick-up 89F into a three pick-up version required certain different switch and a circuit mod to match the impedances in magnetic mode, without pulling down the circuitry in model mode. The custom guitar luthier (with my guidance) did the initial work, then it came to me for some fine adjustments to the circuitry. The 59 switching is a little different, but yes, it is do'able. But you have to know what you're doing and know the circuitry well. It's not something for anyone to do. It's easy for me because after servicing and repairing 1,500 of these guitars over the last six years, I have intimate knowledge of the circuitry, and so I know what's do'able and what isn't. Just be careful with mods, what works today, might crash down tomorrow. Some mods you can get away with, others you won't. Happy hunting. Rock On!

Re-Flash the firmware using the Line 6 Monkey. Possible the program error. If re-Flash won't do it then it will need servicing. Make certain the guitar is registered, then log a Support Ticket in your account.

Should be on the right side, that says "Get Download".

It isn't supported beyond a certain point, and that may be the limit there. I'm a Mac user myself. Check the Knowledge here on the Community Forum, there may be a note about that.

I think it has more to do with capacity of the servers. As far as I know, Yamaha is not involve with Line 6 IT. It isn't Yamaha's style to micro manage like that, it's not a Japanese thing. They leave us alone for the most part. They're pretty cool that way. Micro managing isn't their style in Japan, that's a corporate America thing and with their subsidiaries,... ... think Carla Fiorina when she was at HP.

It's a CD that comes with the GX's, UX1's and UX2's, but is also available as a download.

I work at Line 6 and have never heard of it. There's CD's for Gear Box, POD Farm, Riff Works, Ableton Live (lite, no saves) and Reason (lite, no saves). There's a Line 6 Monkey for doing firmware updates for different products. One of the POD Farms was a free CD in my interface product stash, but the later ones like POD Farm 2 I think you for and even need an iLok which I needed to get my upgrade. Line 6 Monkey v1.72 is the latest version of that, for getting downloads and updates for your Line 6 products.

Never heard of Jam Monkey. I use Gear Box and POD Farm with my GX's, UX1's and UX2's on my older computers. Aside from that stop frame animation thing I found on Google, what the heck is a Jam Monkey?

Tuning off like that will complicate things for you. Tune to standard, then use the Alt Tune or Workbench HD to make alterations. Physically tuning differently, then using the Alt Tune (specially with Baritone) you run the risk of going beyond the pitch tracking ability of the JTV or Variax Standard. It doesn't sound like you have reached that point yet, but maybe skirting that in-between region

Changing string gauges will affect string tension. Tremolo spring adjustment will also have an affect.

"I may not be the brightest in the class, but please, give me SOME credence..."--- No problem, just wanted to make certain that the bases were covered. There were a couple of times when I'd select an attached file, then forgot to click on the "Attach This File". I had selected it, but didn't lock it in. A "duh" moment for me when that happens.

It's an "Attachment". Go to the "Attached Files" function.

Part of it is the physic dimensions, they won't fit the saddles. Don't know yet about the electric characteristics or how they match up impedance wise. That's a ten year old product. Not easy to get parts for.
