Then you either have a blown amp or speaker. Turn the amp off and move the wires from the speaker on the working side to the other speaker. If the other speaker works, you have a dead amp channel. if it does not, move the wires from the speaker on the non-working side to the other speaker. If that works, you have a dead speaker. Dead amp channel means take it to the shop. Dead speaker means buy a new one from Line 6 and install.

Speaker not working

try switching the leads on each speaker. if sound transfers then you have a bad channel. if you get no sound, then your speaker is bad.

The parameters shift up and down while playing

if you're using a pedal. the cat 6 wire that connects the pedal to the amp. can be coming out of the "phone jacks" that line 6 uses, all it takes is for that wire to stretch and if one line breaks . it changes the protocol. sounds like yours is intermittent. put new connectors on each end (after checking continuity),

If it has 2 fuses, the second one might be blown. Try replacing the fuses, if its not that then there is a problem with the amp and you will probably need to take it for repairs.

There is probably a power supply failure or with the power on reset circuit. Likely low voltage to the logic electronics. This is NOT DIY unless you are familiar with electronics.

I have a Flextone II XL 212 combo. When I mute the strings it's quiet, but when I play there is always a hum/buzz with the note on any voice or preset. I've tried different guitar and cord. It's not a...

You have analyzed the problem... with the strings muted, the unit is quiet... that means the problem is with the guitar or cable picking up the noise. Move the guitar around near other things to search out the source which is probably magnetic fields... orient the guitar differently to sniff for the source. OFTEN lamp dimmers generate higher frequency components that can couple into the guitar pickups. The problem is fairly common.

You likely are in an area that has magnetic fields. Also you may have the settings on the amp that accentuates the noise. Eliminating this noise, especially at low levels, can be difficult if you have devices like flourescent lights that have magnetic ballasts.

You might also try running a different source into the amp such as a walkman player to verify the audio can be cleanly amplified. If that works, then the amp is OK.

Plugged my fbv Shortboard into my Line 6 Flextone iii and all the lights went red with no lcd read out.

Try plugging it in and then turning on your flextone, or vice/versa. If not than post it on the line 6 website, they have techs look at those problems all the time.

My Line 6 Spider Amp sound goes out when I plug in my FBV express pedal. Any advice?

Read this cut and paste and verify compatibility as a first step:

*FBV is not compatible with Spider II 15 or Spider III 15.

**FBV is only compatible with POD 2.0 units with pedal jacks labelled "FBV Pedal." It is not compatible with older units which have pedal jacks labelled simply "Pedal."

(NOTE: FBV is NOT compatible with Ax212, Flextone I, II or HD, POD® Pro, Bass POD®, Bass POD® Pro and Spider.)

Note there are apparently several versions. Check compatibility at this site:

I have a Line 6 Flextone III XL. I plugged in my guitar and the sound cuts in and out. It fades in and out. I checked the cable and try using another cable, samething. If I play with the cable by moving...

If the sound "fades" in and out that implies a SLOW change in volume.

If that is what you have, it is likely that there is a problem with the power input or power supply as these are the only thing that would have a time constant to react SLOWLY. Fortunately, this area is one of the easier ones to find and fix.
