    When an amp has cascading or is a cascading amp what does this mean?

    Is the Marshall 3210 a cascading amp?

    I think my amp has this but is it suppose to do it or is there a problem?

    Amplifier stages connected in series to multiply their gain. Each stage in a chain provides the signal for the following stage, called a cascade.

    If you're amp suffers from cascading than you should take it to the tech asap; a way of expeling the cascaders from inside is to turn the gain and master volume all the way to max and play till you wake the dead or until the cops arrive!

    Now seriously, here's a very good explanation of what cascading is - check out the first minute and a half of the video:

    What he said ^

    But really... It's a weird thing to call it. Sure, there are parallell stages in a plexi, but that's because the're being used for different channels. In most other amps the gainstages are all cascaded.

    I usually refer to the same thing as "three gainstages" if it where done to a plexi for instance. I mean, who would call a Soldano SLO a cascaded amp? I'd just refer to it as a "four gainstage" amp and not a cascaded JCM800 with tweaked values (that would make it a cascaded cascade huh?).

    How many promo adds from marshall claim a 'cascaded' circuit?

    there's only 1 that I know of.

    Guys on the net claim it left right and center but marshall doesn't.

    SO on an amp it means you have a different sound available to use ;)

    If that sound 'cascaded' was all over many amps then Gary Moore wouldn't have seemed so suprised about the 1959RR amps sound when he was interviewed by Terry Marshall at marshall (see youtube for the clip)

    I'll try to explain that. The RR head is a cascaded 1959. Meaning that the amp is basically a JCM 800 after that mod. However it doesn't sound like one because of other differences in the curcuit. Like the cathode resistor/capacitor combo of 820R/250uF vs. the single resistor of 10k in the JCM 800. Other things like the treblepeaker combo of the JCM 800 (470pF/470K) before the gainpot vs. the single 68K resistor of the RR.

    That, and of course the JCM 800 has a master volume. But, it would be fair to believe that the mod they did on Randys amp at Marshall was what evolved into the JCM 800 2203. But since the JMP 2203 had already hit the market by then I'd think that the story was that Randy came to Marshall with his 1959 asking for more gain and girth. Marshall already knew that if you hook the stages up in series it'd give you that, so without tweaking the values to match a 2203 they just did a simple mod which would give Randy more gain without a lot of work tweaking a bunch of caps and resistors.

    They are very similar, but with slightly tweaked values. Another one that is even closer to the RR is the famous José Marshall with the diode Master disengaged.

    So, Gary should be surprised when trying that amp if what he was expecting was something similar to a 1959.

    Cascading is really nothing uncommon these days (or after the late 70's) but it usually isn't referred to that way any more. Usually you speak about number of gainstages instead. And todays high gain monsters often have 4 or more, all cascaded but they are not being referred to as "triple cascaded" or "multicascaded".

    That's Palmolive. Cascade cleans up where memorable meals leave off.

    Well the 3210 isnt a tube amp and it doesnt sound like it has a problem but maybe it does or like mickeydg5 said maybe its been modded?

    If i turn the master to say 2 then i turn the channel 1 volume up it stays clean till about 80-90% then starts to distort. SO i figure 80-90% would turn into a "crunch" channel.

    At any point i can turn the "boost" volume up and i can hear that channel regardless of where the volume is on channel 1. If i mix them just right i can hear a clean sound with a distortion behind it, or vise versa. I can also turn them both up and when the 1st channels reaches the crunch gain it just seems to add more gain to the boost channel.

    When i put in a foot-switch then those channels become independent and then the boost channel has the full gain as if both channels were up but now i have in independent clean channel.

    Its cool because the sound has a weird ghosting sound to it and it combines both EQs or EQ and the tone control together giving it a more full sound.

    My first Crate CR-65 does this same thing and it has a unique sound to it as well. You can play threw the front, the rear or "combine" and it doubles the sound of the front with the back and also adds the EQ from both front and back. The combined sound is very thick and has a heavy distortion.

    It's a great comment! :)

    after you've eaten your meal you can go and play your cascaded marshall. ;)

    Easy killer, he may be a little odd, but we tolerate it round these parts.
    Plus if you wish to stay on the good side of the mods here you'll leave him be.

    Pass it on....
