    Hey guys! I’m obviously new here, and definitely new to old Marshall’s.

    I have a DSL40C and would like to get something older and enjoyable.
    But, I need some help finding a decent Superbass that preferably hasn’t been modded. I’m looking at this particular one on reverb and I’ve been trying to compare the guts of it to other ones for that time.

    It seems like there may be some work done, but I need one of you guys with a better idea to help me spot the potential differences.

    Thanks!
    Okay, so I can’t post a link yet since I’m too new.

    If it’s the one from Spain, it’s just about stock. The only thing I see is the bias supply capacitors have been changed. Perfect

    Thanks! Could it potentially have had a drink spill into it? Looks like it has liquid stains on the inside chassis.
    What's the going price for these usually?

    Seller says that it has the later transformer from 78-81. Good, bad?

    I paid $1800 for a '77 a few years ago (approximately).

    This one? I don't think it's a drink spill, it's just the typical accumulation of dirt on the top of the chassis. Looks like new glass too (not that a new JJ is better than the RFT it must have had originally). It's surely not on the cheap side, but he's open to offers. Original and cosmetically looks very good. I would ask for more detailed pictures.

    Yeah, that’s the one.
    I’m in Australia, so after converting, that seems like a reasonable price.
    I’ll ask for some higher detailed shots, especially of the internals.

    From what I’ve seen on YouTube, it looks like I might have to buy an attenuator as well. Hahaha!!

    Also, he mentions it was originally a US amp with 6550 tubes. But those US amps were only 120V? So was the transformer swapped to deal with 230V? I dont really understand it

    Don't they have a mains switch?

    yes.
    I don't know if that was a good price or not. It was in good condition. It was the more reasonable price of what was available at the time. Stock for the most part except for a ppmv that I left in.
    I paid $1200 use for a '79 jmp 2204 just a few years before that. It was completely stock. I ended up changing the filter caps and the ohm selector switch to the modern version because the selector plug kept falling out.

    Looks like it. Maybe the confusion at my side comes from the US 2204 that didn't have the selector switch.

    I haven't played with a ton of these, and export/import laws may vary, but switchable or no, all that I've seen have come with taps for most voltages. If there's no external switch it should be fairly straightforward for a tech to switch it internally.

    Just saw the gut shots, it looks like you should have switchable mains, so easy peasy (not British, may have spelled that wrong...). I paid a bit less than that for my '74 a few years back, but prices are obviously all over the place, and I may have actually done OK with that one (for once). I DOES look very clean, so I would expect it to fetch a good price...

    Thanks for the help guys.
    Sooo apparently that particular has sold and he has another one, but isn’t listed.

    I’ll keep you guys posted.

    When you are working out the price, factor in you will get hit with GST and other fees by Australian customs. Best to work that out first so you don't get caught out.

    I'd walk away. If I was dropping that much money on something sight unseen and taking the leap of faith that will make the trip halfway around the world and actually turn up, id want to be very comfortable with the seller.

    That's my thoughts exactly.
    He seemed pretty pissed when I started asking questions about getting some more photos.

    Here's one of his messages:
    This one is not on sale... I'm waiting for ending with this question to remove from here.
    Let me know if you are interested in other Superbass from the same year and in very good condition too.
    Really if not I don't understand why.
    I have many articles for sale and positive votes. And this is part of my job and live. Dive on internet and you could find kitarshokak.

    He's probably on here, but that hasn't done him any favours.

    Like others say, walk away, it's quite high in price really. I'm sure there was a SL from 72 went on ebay UK for £1300 last week.
