Hello,    New amp I procured and I am hoping to get some Q's answered regarding. 

It did not come with a footswitch and being new to all of this I do not know why I need one or which footswitch to get ????

Also, I was told by the original owner that it is quite than it used to be and may need a new tube.   Also do not know which way to go with this ...   

 

Last point is when switching over from clean to overdrive it is buzzing and I am not sure why...

 

After hours on youtube and reading the instruction manual I am even more confused. 

 

Thanks in advance for comments/advice.

I've got an Origin 5C, about 6 months old.  Has worked fine and is a fun little amp.  But last night I had my first issue.
Got the rig set up, with front-end fx, and also some fx in the loop. Warmed it up, then played a few bars in low power. All worked fine, so I switched to full power, and stepped away for a few minutes to let it warm up some more.
When I came back, it was still powered on (light and mild hum), but the footswitch was dead and there was zero volume. Not even cable crackle when plugging and unplugging the guitar.
I messed around with all the connections. Pulled everything and plugged in directly (also checked the instrument cable). So, guitar > cable > amp. Still no volume, and just a slight hum (very slight; it wasn't ampliyfing anything, so this was just circuit hum).
I dissambled the the thing, to check tubes and connections. Everything looked grand.
Reassembled it, and it worked fine. Played for a good 10 or 15 minutes at medium volume, and it was a charm.
But then the volume started dropping. Would come in and out. Then it dropped completely, and the footswitch went dark again.
I tried connecting an external preamp into the return (with a dummy plug in the send), but no luck. Footswitch was still dark.
Hum but no volume.
Haven't tried it yet today, but I'm expecting the same behaviour. My assumption is that there is something that goes sideways when the temperature gets up.
So, two questions:
1 - Is this a power tube issue? I haven't noticed any other problems or symptoms of bad tubes. And, like I said, it's 6 months old. Never gigged, but played loud fairly often.
2 - What's up with the footswitch? I can't find any schematics of the Origin series, and I don't care to go tracing. So, I'm not sure exactly where the FS fits into the circuit. I was wondering if that symptom might help to diagnose.
Anyway, a great little amp, but it's acting up!
Has anybody had or heard of this issue?
Thanks, friends

Hi there.  I am not a native but I hope you'll be able to get me right.I have been using Dsl 15c for about 2 years and all of a sudden the amp stoped producing any sound. All controls freeze, footswitch is non responsive. Led’s and tubes are still lit. No pedals in line. I turn power switch off then on and hear sound like a relay click in the background and then sound immediately cuts out.  My tech told me the problem is 99% in the microcontroller AT2313 because inside all fuses are still intact.  He was able to read the code and fix errors that cut the sound out. However, it did not help because some of microcontroller ports were damaged(most likely it was a factory defect). Is it possible to re-record the code to new microcontroller or maybe there are some other options to consider?

Thanx.

There is a loud popping noise when I am switching from ultra gain to classic gain channel while still holding or playing, but does not occur when going from classic to ultra. Also my loop pedal's volume is significantly lowered when on the ultra gain channel. Could this be a tube or footswitch issue? Is it easily fixable or do I need to take it in so someone can take a look at it? This was also just purchased on February 3rd 2018. Any help is much appreciated because I absolutley love this amp.

My JVM 410C doesnt have any volume coming from the channels.

 

One switch works green yelow, not red.  Works fine with switch two.  Switch three works green and yellow, not red.

switch four doesn't work at all. 

 

No sound out of these channels without footswitch.  Same results.  Now, making a poping noise when turned off.  I just got htis amp in June.  Played a few weeks and then boom, nothing.

 

I tried using the FX Loop in back.  That's when this whole thing started.  As I correctly plugged in as instructions say, it immediately didn't make sound in these channels.  Unplugged, guitar going straight in, same stuff.  No volume through these channels.

 

The tubes are red, all glowing.

 

I need help.  Thanks.
