Spider IV 150 - Amp simply shuts-off when playing.
by bluebluetones on 2011-03-07 07:25:51.8450

Hi all,

I wrote to Line 6 a month ago about a problem I am having with my Spider IV 150, but did not hear back from them other than an email stating the issue may have to be taken up in this forum.  I have decided to write here in order to contact other players with similar experiences, or for further help from Line 6.

Here is the email I sent Line 6 in February:

     I would first like to say thank you, as have been very happy with my Spider IV 150. Like a lot of players, I go through different equipment each year, but this is the longest time I think I have stayed with one single amp!

My question is regarding a post on the Spider IV Discussion page. I read with interest from a couple of writers who had a problem with their Spider IV in that every once in a while it would simply power-off and then restart. I have had this problem as well (approx 10 times) and, only playing as a hobby, did not let it bother me too much. I bought the amplifier new on December 23 2009. Recently I had another episode where the amp shuts off with no warning and then powers up again - I thought I would write to you personally.

My question is: Is there a known fix for this issue?

I should also mention that the amp has had this issue through 2 of the firmware updates, which makes me think it may be a hardware problem? I am eager to have the problem resolved, and any help or additional info from you would be greatly appreciated.

I think most players can understand about my reluctance to take this amp to a service centre for a couple of reasons.  Firstly, having read that more than a few players have had the exact same problem, I don't feel I should have to pay for what is a fault in the amplifier.  (Even although it appears to be happening on a random selection of the amplifiers.)

Secondly, the random nature of the problem will likely mean that the amplifier will come back to me with the service centre saying, "We left the amp on, and it seems to be working fine."  I had a similar experience with a SS Fender Princeton a few years ago - it was murder trying to convince the repair shop that there was something wrong with the amp, as it worked well most of the time!  You know the feeling when they're looking at you sideways, and going, "HHmmmm?"

Anyhow, I don't know how to have this problem solved.  It's not a huge issue, but now it feels like I am always waiting for the next "episode" where the amp powers off, and it has taken away from the enjoyment of this very musical amp.  I hope everyone can appreciate how I feel.

Any other writers who have had the same experience, feel free to chime in.  Wouldn't it be nice to hear from Line 6, and to have them say they have located a faulty component in certain amps, and please have it returned to be repaired?  That would be fantastic!

I appreciate you all taking the time to read this!

There is no way speculate what it is that is causing your amp to act this way. It is even entirely possible that a voltage issue in the locations you are using the amp may be causing this. Are you having this problem in all locations that you used it? Make sure to test at different locations. There are a number of components in the unit and any number of those can possibly fail and cause the amp to have a problem. Only an authorized service center can take a look and verify what the problem is.

I would suggest taking it to a service center and showing them the problem if you can replicate it at different locations.

The last time I spoke with a customer that was experiencing automatic "restart" of a digital modeling amp's system software was probably 2 months ago.

I believe it was a Spider IV 15 watt. There was a bad component on the mainboard that was causing the firmware of the DSP to keep resetting. Prior to this caller, I can't remember when I'd fielded an inquiry personally like this... perhaps last Fall sometime. My point is, it is not an everyday occurrence from my experience working in Support.

Unfortunately the only person who could verify at this point is a repair center technician. They are the only ones who have the tools and knowledge to diagnose component-level issues. The extent of our answers here on the Forums is limited to things that end users can test for. Once you've tried a system reset on your amp, tried operating the amp at various locations, you've pretty much done all that you can. If the symptoms continue, it escalates to a repair tech's diagnosis.

All in all, these amps are digital systems. They have more in common with a computer than an actual vacuum tube amplifier that the sounds are modelled on. I can tell you that I've seen many computers (Windows PC's and even Mac's) get to a point where the system has been in use for a while, programs installed, changes occur in the operating system, possible components go bad on the motherboard, RAM or hard drive and you experience a restart or "blue screen" or "sad Mac" when powering up the computer.

The Spider amps occasionally experience similar issues.

Sorry to hear about your issue. I'm not sure that there's much else I can add to what Hugo already touched base on previously.

I've had the same problem with mine too....only played it 3 times so far.  Just bought it brand new because the spider 3 i had before was so reliable.  Now with the spider 4 that i've literally played on 3 different occasions (only having it a week) has aslo restarted 3 different times so far.  Honestly I think I'm about to just take it back.  I don't have the time to chase down the right service people to take a look at it.  I'm just glad to see that I'm not the only one with this headache.

The resetting error in the Spider iv series amps is reported by several users.

I started my second thread about it here:

From thread:

"Line6, now that the bad component has been identified, are all  service centers informed about this and what problem it can cause?

Will you make an official free repair offer for this, just like the X3-Live problem?"

I just got the Spider IV 75 yesterday and today was my first chance to play it for more than a couple of minutes.  I've already updated it to 2.00.

Just today in the last 30 minutes, it's already restarted 3 times.  I'm a little disturbed to see on the forums that so many other people are having the same problem.  I've always thought Line 6 products were top notch, but now my faith in the company has been shaken.

jdm, since you just got it, I'd bring it back to the store for exchange.

It works fine now.

Hello I didn't see anywhere on here where they have found a fix for this, correct or did I miss it?  I just purchased a spider iv 150 about 3 weeks ago,, and mine amp has done the same thing a couple of times while playing it,, at first I thought the plug wasn't in good, but the second time it happened, I was playing along and bam off and on,, real quick. I am wondering if I should take it back and trade it for something else,, I bought a line 6 variax guitar, amp and shortboard all at the same time,, now I am begining to wonder if that was such a good idea or not,, the amp seemed to be okay, except for higher volumes and then some of the pre-sets seem to either be too trebly or harsh. Anyway I just thought I would chime in on my problem with the amp also, seems there are getting to be quite a few people with the same problem. I will keep watch on this site to see if line 6 has any answers,, but if not I may be taking mine back. I have a fender pro 185 that is over 20 yrs old and haven't had a problem with it, but I was impressed with all the sounds and effects that this amp has,, it would be a shame to have to return it because of some small glitch, but what if after the warranty goes out, the small glitch turns into a major melt down? Thanks

If you bought it new, yes, take it back and exchange it for another one.

As for the settings at higher volumes - the factory presets are meant to be starting points for making your own settings.  Tweak to get the sound to your liking, then save them.  Note that when playing out the room (and if you have the amp mic-ed) will make a difference on tone, too, and may require further tweaking.

The information above may not be current, and you should direct questions to the current forum or review the manual.
