    There are 'good' trolls, and there are 'bad' trolls.

    Dreyn is good people. He may seem odd to you...but if you take the time to know him he really does make perfect sense.....most of the time

    Well, if bon scott was into quilting he'd be here right now.

    There's 'being tough' at your own expense. ;)

    I've plonked down the $5000 for the cascaded marshall. I have some stake in the game. (and that's just for the head. no cabs in that price :( )

    I wondered if I should have picked up that NIB RR on CL for $2500? :hmm:

    The 5000 was the new price for these things in this country. there were discounts around slightly later and S/H with a white matching cab were to be had for 3000. guys were desperate to get money from a product they thought was close to stock.

    maybe 1 will get offered for sale each year if we're lucky. slowly falling into the hands of guys who won't part with them.

    For the cheap price of the JCM2000 amp they make an incredible sound and kinda make the 1959RR seem way over the top. But the RR is an amp that's WAY OVER THE TOP! ;)
    If you're struggling, FORGET IT! you don't need it!
    If you love abit of 'historical items', it's great!

    How many dollars do you put on a powerful warm sound? that's up to you.
    DOn't buy into the RIP OFF game either. ;)

    I was stunned about the retail price and then i was even more numb that they were walking out the shops. I knew of 3 that went very quickly out the shop never to return.
    I was luck towards the end of the production run. otherwise I wouldn't have 1.
    the confusion that's out there gives others another chance too.

    There was a set posted on the local CL that stayed up for a hell of a long time if I'm not mistaken the full stack started out with an asking of $7000 with original boxes then over a period of 8 months or more I believe it ended up selling for under $5000 or less. I'll have to keep an educated eye open in the future

    Cascading means adding gain stages! Each time you add a gain stage, you add more clipping and overdrive, as the output waveform from each stage exceeds the voltage supply rails of the following stage!

    On the JVM410 (for example) in the Crunch Orange mode, the circuit is exactly the same (in terms of number of gain stages, circuit layout) as a 2203! There are differences in values, and voicing (for example it doesn't have the treble peaker circuit of the 2203..) - but the circuit is essentially the same!

    But when you go to Crunch Red, or into the high-gain OD channels, relays progressively switch in extra cascading gain stages, which gives a lot more gain and clipping! This is why the 410 can go from something similar to a 2203 sound-wise (or exactly the same if you change a few component values!) - to a high-gain monster!

    Is the 3210 a cascading amp? It works in a weird way and ive read another member call it a cascading amp.

    http://www.drtube.com/schematics/marshall/3210-iss7.gif

    MarshallForum.com - Mosfet Lead 100 - Documentation and Schematics

    Its hard to explain how it works because i dont fully understand it. It has sort of like 3 channels but they all work at the same time. depending on where the gain and volume is set for each.

    It has a master, and 2 volumes and they work together mickeydg5 says its blending both channels which i guess it kinda does but then at a certain gain level of channel 1 it just turns into the boost channel. When the footswith it plugged in they are seperate no "blending" they become 2 distinct channelsclean or crunch 1, and OD on ch. 2 either or with the footswitch no blending in this mode.

    This is taken from and was in regards to a conversation about a MG versus a 3210 and its situation:

    "The amplifiers use two different switching systems.
    The MG has a mechanical switch.
    The 3210 has a transistorized switching system.

    Honestly if you are getting bleed through from the other channel then something is awry with the switching system. It sort of sounds like it could be dirty/faulty footswitch jack or something else blocking full turn off of one channel."


    The bleeding is not normal operation for the 3210.
