It doesn't have to be a bad monkey. Just an example of what I use. An SD1 should be fine.
The overdrive from the amp by itself should sound better than any pedal...
The key is to get several tubes and roll them around into different positions until you find ones you like.
There is JJ, and Gold Lion, and Telefunken, and Mullard, and Sino etc...all different flavors.
I mean -from what you describe, the preamp tubes are just old and weak.

I definitely need a new pedal. The SD1 sounds like fuzz and lacks tightness. I honestly hate this rig and have major regrets. Hard to believe I'm saying this about a JCM800...
If you hve a weak pre ampmtube - IF - that will help. Perhaps you need a good Overdrive pedal instead of the distortion. It should really smoke.
Since you hate it so much,
Send it over here, and it won't hurt your feelings anymore. I'll take care of it, and keep you safe from harm.
His amp sauce is weak!Overall right now the amp sounds anemic which points to a circuit/tube issue. Even the pedal won't cover up with the extra juice in front.
I'm gonna tell you my DSL40 would eat your Marhallall as is right now and it shouldn't. But let's tune it and see where we get.
You know what? You're right on track. Most people get an "800" and are immediately underwhelmed because they have utopian dreams of molten hot liquid gain leads and Metallica chugs flying all over the place. 800s are not like that. They need a ton of help to do that stuff. In their natural state 800s are little more then AC/DC-tone-type amps at best. You're on the right path boosting it with an overdrive if those high-gain tones are your style, and an SD-1 is tried and true, but there are some things you need to go through first. What you need to do first is you need to make sure it's working properly. These amps are old now. There's no telling what kind of monkeying around has gone on in there or what components have tired themselves out. Bright caps get snipped, bias caps leak, filter caps hum, etc. As mentioned already, make sure the tubes are good and the bias is right. Spend the $75 and get it checked by a tech of you can't do it yourself. Secondly, get the damn thing loud. That's where they thrive. Does a stock 800 sound good on 2? It can, but it's not at it's best. Thirdly, get more familiar with it. One you know it's healthy, then you can really start to explore the badassedness that is a JCM 800. Fourthly, and this is optional, run it into a 4x12 cab. All those magical JCM 800 tones rocking around in your head were done with 4x12 cabs.I definitely need a new pedal.

What guitar and pickups are you using? What kind of music are you trying to play? These things matter. Since this amp is new to you I'd have a local tech check it regardless of who the seller said already looked at it. For a guy to look everything over and tweak the bias doesnt cost much. You want the bias to be at or around 38mA. A new set of tubes isnt a bad idea, I like Chinese tubes in this amp, Sino, Shuguang, Ruby, like those. Keep the old tubes as spares.I definitely need a new pedal. The SD1 sounds like fuzz and lacks tightness. I honestly hate this rig and have major regrets.

Concerning distortion / overdrive pedals: That's not the Marshall sound.
Concentrate on getting all you can out of the amp, without the pedals.
It should be plenty crunchy without any pedals, if it's working right.
That's weird. The quote you responded to is attributed to me, but I didn't say that.I couldn't agree more. Why spend [$3,000] on an amp, and then distort it with a bunch of pedals?
Make a decision; The amp defines your tone, or the pedal(s) defines your tone. Neither one is wrong, but just don't have [$500] worth of pedals in front of you, and complain that you "just can't get the tone I want".
I have one pedal; a Pitch Fork octave pedal, and it's for one song only...Shot Down In Flames, to get that dual guitar rhythm sound. And it works, it actually sounds great.
Make a decision: Do you want [this] sound, or [that] sound?
That's weird. The quote you responded to is attributed to me, but I didn't say that.
I think that's the point. Get the amp sounding healthy 1st, then add some push, if necessary. It should be subtle & usually, a clean gain boost is better than some sort of distortion device. If running a distortion, turn the distortion off, but turn the boost up...For 80s hard rock, an 800 needs that push. It doesn't sound like a pedal, it sounds like an 800 pushed.
