The clean channel is absolutely perfect but when I move onto using the overdrive channel it crackles, either when moving the contour dial or the volume dial. Then on top of that when I change the master volume it also effects the distortion. The differences that apply are an extreme increase in volume and an extreme increase in treble values. The amp is very old so it could just be that. Nearly 10 years old now.
Please, take it to a tech in your area, or look for a good one to ship it to. An 2007 amp is not old at all.

Either the control is damaged (happens if they get hit) or it is possible the circuit board it is mounted on has broken solder OR worse, a crack near the control. The unit will require servicing. Parts are readily available.

There are many models of Marshal amps icluding 15Watt types.
First thing to try is to see if headphones have normal volume. If they do, then the headphone jack switch that connects the speaker is LIKELY bad.
If the headphones do not have any volume, LIKELY causes are:
1. Fried output power amp
2. Volume pot is broken or has bad solder joints to the circuit board.

There are many things it could be... I often quote the probabilities based on many ears experience and the symptoms the person posts.
Based on what you have posted, there is an intermittent... the unit vibrates while operating... there could be a loose connection, however my guess is you will find bad soldering at one of the pots that control the distortion. The solder often breaks loose as the sometimes support the circuit board from the leads of these pots. Also switches that solder to the board and sometimes jacks for foot switches break loose.
Open the unit and inspect the solder joints. It often takes an experienced eye to spot the tiny grey ring around the solder meniscus that signals a failure.
