Hi, I've just got an AS50D acoustic amp so a mate and I can do acoustic gigs. Is it possible to run an acoustic guitar in channel 1, and an acoustic bass in channel 2 along with a mic? 

Hi My AS50D has developed a loud hum

It doesn't change if If connect different guitars or micsand changing the input levels has no effect

But it does get louder with the master volume

It sounds like a problem with the power supply is it an easy repair?

I live in the far north of Scotland so shipping is a problem

Here is a video of the hum

I purchased an AS50D amp a while ago, and while I've otherwise been extremely happy with it, when it arrived the caps fell off many of the knobs, which is obviously annoying since I can't see what the current settings are.

I contacted the (Swiss, German-speaking) vendor, who contacted Marshall, and they shipped me a baggy of replacement knobs.

Naively it appears that I should be able to pull the old knobs off and push these on (as I see no evidence of a set-screw anywhere). However, applying reasonable force with my hand or even prying with a screwdriver, I can't get the old knobs to come off. I don't want to risk applying a large force until I'm more confident that I'm following the correct procedure and won't break anything. 

So, my questions are

- are these in fact the correct replacement knobs?

- what is the recommended procedure to replace the knobs?

- if I am supposed to simply pull the old knobs off, should I expect to apply a lot of force?

- if not and these are the correct knobs, what is the recommended procedure to replace the knobs?

Dear Marshall,

I have the Marshall AS50D.

Can i use the line out jack to connect a wired headphone to it so i can use that as in-ear monitoring? Or will it blow up my headphones, my ears and my head?

Could i use the D.I. Out to connect a device like the Fischer Amps mini body pack, so i can plug my headphone into the Fischer Amps mini body pack and thus have a volume knob close at hand? Link: http://fischer-amps.de/en/in-ear-monitoring/mini-body-pack-xlr-oder-klinken-eingang.html

Or does Marshall have it's own solution for this?

I use the Marshall AS50D to sing and accompany myself with the guitar. When i have a gig in a restaurant they want me to play silently (lol) but then i have trouble hearing myself because of the ambient noise and i start singing out of pitch which is like a weapon of mass destruction.

But i can't say: stop talking, stop eating and stop using your cutlery, because, well you know, it's a restaurant and all that. So therefore i need an in ear solution. Preferably wired because wireless is too expensive and not necessary too, since i'm not allowed to stagedive in a restaurant (anymore).

Best regards,
Johan

My AS50D acoustic combo has been working beautifully and I use it for a weekly residency gig.  Yesterday the sound suddenly crackled and faded to silent on both channels.  It was very embarrassing but I finished the gig acoustically.

When I got it home it worked fine but then after a few minutes it crackled and faded again.  I wonder if it's a problem when it warms up?

Can you recommend a course of action?  I need to get back up and running asap and reliably.  Is it likely to be a simple connection that needs re-soldered so I can point an electrician in the right direction or should I just dump it as a bad job and replace with a  more reliable amp?

Thanks

what footswitch is used with theAS50D? Will the PEDL91003 ? It said in manual PEDL-10029 can not find one to buy?

thanks

Hi all, 

Just a basic question. Wondering if the fx loop in the back of my amp was Line Level. Is this universally true? Are all fx loops line level?

Thanks.
