SOURCE: I have a Line 6

It is NOT likely that any significant damage was done to the amp. Find a COMPETENT tech that knows how to fix, rather than replace boards.

Protective circuits kicking in. You may be overdriving the preamp to a clipping condition the amp sees as a problem. If it is under warranty, contact Line 6 and see if this is normal for this amp. It should not be, but you never can be sure.

Peavey tnt 115 blowing fuses


your either overloading something cause that's what pops fuses. My guess is that what your plugging in or into has a ground issue. I'm wondering if it does it with nothing plugged in at all. I would say if you have nothing in and it does it, you need to find where the ground issue is. that's my best guess

Behringer djx700 has no bass


Check that all the eqs are set not to cut bass, check there are no effects on and that the XPQ is off. If you still have the problem how sure are you there is no bass coming from the mixer? Have you tried it with another amp? We had one hire customer who had the same problem you describe and his amp had a crossover and it was set to act as a mid/top amp and wasn't giving him any bass, unsurprisingly, switching it back to full range sorted it.

Electronic circuit diagram for a bass collection bass guitar Japanese 1988


I understand your pain - was googling for similar, and came across this post, 5 years prior. My SGC Nanyo Bass Collection has just started to play silly beggars with the pots, and a bridge fault. Nowhere online seemed to have any details of the wiring, as the problem is, as you say, the fact that all of the tone and volume pots are based on a printed circuit board. If theres a nick or short on the board, its a pig to replace, and I really wouldn't like to have to wire any pots onto it. I'm currently looking at the options of ripping out the old electrics and wiring it from scratch myself. If you're still after answers, good luck!

PS - noted that none of the previous replies are relevant to this - mostly going on about the amps or a Fender guitar??!

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:

Is it still under warranty?

If so take it to your local Line 6 service center. http://line6.com/service_centers/

Before doing any of this you may want to try another Line 6 amp. Could be a problem with the amp itself.

I don't know....


Hi,

As you know, when you plug in your headphones, the amplifier cuts the sound to the external speaker, routing the signal through your headphones instead.

When you accidentally pulled the headphone plug from the jack, it apparently damaged the jack, which has the relay attached that routes the sound to your headphones.

Replace the jack, and everything may be OK. I say may be, because the jack is attached to a circuit board in these line 6 ampllifiers, and if you have damaged the circuit board, you will have to send it to line 6 to be repaired.

The downside is if it is not under warranty, it is an out of pocket expense, and Line 6 will not even give an approximation on how much a fix will cost. I have gone through it with Line 6 in the past, so I am very aware of the procedure. It is also a limited warranty, and they may not cover this particular damage.

However, if you are straight with them and they feel obliging, they may fix it under the warranty, if it is still active on your amp.

I had a spider 2 x 12, which was switching between amp models by itself, and they told me that because it was not under warranty, that I might want to consider NOT sending it to them, and just buying another amp. I didn't like that advice, because they seemed as though they didn't care about retaining my business.

Now, something to consider is taking it to a reputable amp repair shop (preferably one that is Line 6 authorized), and see what they can do. Maybe your clip is just bent, not allowing it to spring back from the contact switch that cuts off the main speaker. It could be a very inexpensive fix, but you need to have a shop actually take a look at it up close and personal.

Good luck. I, for the most part, enjoy Line 6 products, and their excellent distortions. Just remember, their amps tend to have a LOT of problems. You can find sites that list many many dissatisfied Line 6 amp owners. All that electronics (on board effects, soft buttons and switches, etc.,) make them vulnerable.
Now I mainly use my old reliable Marshall 1/2 stack with my Line 6 pod, as well as quite a few other pedals.

You would be amazed by the fact that you can still get pretty good money for a broken line 6 amp, maybe get something with less bells and whistles to break, and go with off-board effects pedals and processors.

Please excuse me for adding my own opinions, I am quite well versed in this type of advice having grown up in a luthier / guitar shop and have been playing for 38 years.

Good luck with everything, and if all goes right, adn it is just bent, it may cost you as little as a few dollars to fix. I'll keep my fingers crossed for you.

Thank you for using FixYa.
