No prob mate. About preamp tubes, I have changed them to Tung-Sol's, really nice overdrive. There are no real mod's on the forum, just some tricks to use with MA... please check this link below for details, basically you put overdrive pedal in effects loop and use it as a master volume control, I th...

Hi there, welcome to the MA club, and try some of sound tricks we posted here on forum to make it sound even better :Thumbs Well I guess one of ways to put this amp to lower end shelf is a black power switch in it...just cosmetic downgrade to make it look less like JCM's and other big brothers. And ...

Now maybe some white piping...

White piping is allready shipped to my adress , so new pics coming soon.

I always thought that one part of the iconic look of Marshall amp is the red power switch, which MA lacks, so after checking out mods at JMD part of forum I decided to do it myself. Bought the JCM switch for 5$ , and replaced the old one, a bit tweaking with wires since you have to swap position in ...

It looks really good, like another amp, I guess it's cause we are used to see all those Marshalls with red switches and that's the part of the iconic look. I will post pictures today. Well, I work in civil engineering company and we have electrical department, so I had talk with engineers there, if ...

Ok, so I got the red switch, replaced the black one, same wiring connected again and....there is a light, but it's on all the time :dunno Switch is shinning red all the time, it works normal for turning the amp on and off , but the light should not be on when amp is off, what the hell is going on he...

I don't want to overtake the thread but regarding the pic I posted... This is a classic Hendrix photo, just shows what a showman he was really , I remember documentary about him and one of those guys behind amp talks about it....''I was behind the amp holding it while he was...long pause...fucking i...

does it hurt to the amp if i bring the guitar close to the amp?

Nope, it hurts only people behind the amp

Oh well, GT-10 is a beast, I guess you don't need pedals anymore , lol. I went to local GC here, my friend work there and this guy was trying some amps and he started dissing MA as shit amp for amateurs, so I finally got pissed off and invited him to try the SD-1 in effects loop. Well, he didn't bel...

Yup, Marshalls sound best when loud, but you know how the business goes, sound guys want to kill you, you are too loud, bass player gets angry and cranks his amp, drummer looses it and hits the cymbals twice as hard....and it goes on :) That's why this master volume thing is handy, for playing at sl...

That's what I'm talking about :jam Really nice sound Phano, master volume is really doing the trick, I guess it let's you blend that preamp distortion and small amount of power tube clipping and you have the MArshall sound. I just can't imagine playing my MA without it anymore. I tried another thing...

Ok, thanks, I am ordering the red switch from Ebay, and will post pics after replacement is done.

Great work on that amp!
I hate my MA's black power switch, and want to remove it. How much of a work is to install this red light switch? Any special requirements for the amp ?
I have a friend who is a master in electronics and repairs, couple of beers and red light will shine on me!

Well my idea was to buy some Eminence Governor speakers, 75w each, but it's on hold now as I am buying summer tyres for my car :bgrin Anyways, I have found out that Bad Monkey set as clean boost and pushing clean channel, volume about 4-5 gives amazing light blues break up. Of course I set overall v...

Yup, my SD-1 is on all the time, gig or bedroom, for more volume just crank the volume knob on pedal, equals full master volume on other amps. What's more interesting is that now you can blend preamp and power amp volume, too much power tube saturation doesn't sound good,it squashes everything, you ...
