Stoked!!! I got me a cool new amp... It's here

Making that cascade switchable from plexi to 2203 is just a push/pull using the normal channel's volume as the preamp gain when engaged...very simple. I do those for guys all the time. Just a DPDT. There is a layout/schem around for it as well...if you're interested I can point you in the direction.

These days I am trying to approach everything from a logical perspective and Logic tells me that you CANNOT get pissed off at someone for using something that you FREELY posted on the internet.

that just doesn't sound logical

Well, I guess what I'm getting at is that if you want to be able to keep the volume the same when you switch between the modes and have it footswitchable, it is complicated. If you never use it live or never switch within a song and have time to walk over and change it when you want to switch you can do it easily.

I'm not gonna get into a debate...because this thread is about something else, but it can be done with 1 DPDT switch or a simple relay and a normal shorting footswitch. As Steve mentioned there would be more complications if you want the volume the same. I have an amp for sale locally that has several modes just using a toggle, but uses a push pull to go from Plexi to 2203(4). I have a relay for a solo boost that is footswitchable, but I just built the amp to cover several genre's. If you play larger venues where your gear is in a rack not close by then making them footswitchable makes more sense.

Making the cascade switchable is gonna be a bitch. It will require much more than just a toggle. Trust me, Steve's amp basically can be switched between a stock superlead and a cascade and it requires a lot. You can't do this without a lot of additional circuitry... It can be done, but it is a lot more difficult, time consuming and expensive...

You're (of course) absolutely right. You can do this with one DPDT as you said. I've seen schems/layouts for this many times. Here are a couple of ways to do it (one with DPDT):




I was wrong. Sorry if I confused anyone here with my response...

I was thinking about my design... I designed my amp so you could balance the volumes when switching between modes and it is also footswitchable and manually switchable via toggles on the amp. That is why my design is more complicated and why I responded the way I did.

Have you heard Jerry's amps? :confused: I'd leave it alone or send it to Friedman.

Jerry isn't modding it to one of his creations, designed for something all together different. He's going to be doing a very specific mod, that I am confident he knows, and will do well.

I knew what you were saying Steve, and I thank you for it, because I see it like you were just trying to put some 'Food for thought' info out there.

Seriously, why get it hacked up to a 2203 until you hear and feel the raw power of the 12000. So Jerry does Rockstahs mods now? Rockstah yelled at Steve about copying his VH mod on the internet about this I do recall. I would feel a bit better sending it out to Jerry though, if he indeed does the same mod, Rockstah was recently pulling Cameronisms with men.
Yup and for the record, he was bummed at me me for saying I would tell people who were begging for their amps and money back when he was unresponsive how to do the mod. Which he really shouldn't care about since there still exists a thread on metro that spells it out EXACTLY. Someone also posted gut shots of one here when trying to sell it. I never saw a thread on metro with schems and layouts. Finally, I never copied that mod in an amp for myself or performed it for others. I have shared exactly what the mod is though... I see no harm in that since it is public record to this day on metro...

Steve

That's basically what I'm saying ;) Mark (Rockstah)posted all the information on the Metro site, so If someone was smart enough to pay attention then No harm no foul . If he is going to get pissy about it, then he really does not have a leg to stand on as he is to blame for leaking the info. You can't share stuff freely and then get pissed off at people for using the information just because one day you decide to charge money for it IMHO.

Just a FYI, He most definitely posted a picture of the MOD 5 either directly or indirectly. He used to have links to all of his tweaks posted in his signature on Metroamp. If you ever clicked on any of the numerous pictures that he posted links to, it was there plain as day.Or you could go to his sig and click on Rocktah tweaks and mods and bam.... There they were.
Id gather he has since taken them down.

With all this said, I still think that he will make money with the mod because not all of us are handy. If I wanted that sound, Id send Mark my amp in a heartbeat, but there are so many other amps out now that I feel cover that tone, that there is no need for me to and I'm kind of done with that sound......... (only at this point in time... That could change in the future LMAO :D ) ;)

Funny, he was busting your balls for this. I saw a thread on TGP where he was begging for a gut shots of a Cameron. When the person refused, he was saying how people helped each other out on the Metro forum, that it's no secret, and on and on. The when it come to his mod (or whatever), it's a big secret and wouldn't give up the goods.

Schaf
Well then, allow me to give up the "secret":

1) buy a stock 12 series super lead or equivalent
2) convert the preamp to 2203 spec (cascade the first two stages, put a 10k on the second stage instead of the 330u/820)
3) lower the filtering (40uF mains, 16uF screens, 16uF PI, dual 32uF preamp.)
4) put in a LarMar PPIMV
5) Dime the preamp gain and master you now have and adjust the PPIMV to taste for overall volume....

Congratulations, you're browned for about $20-30 in parts and some soldering time + the cost of the stock Marshall or Metro you bought... In general this will work with any Super Lead style amp 100 or 50 watt - you're just doing a 2204 cascade on a 50 watt...

As I said, thisinfo is in a thread at metro to this day, so I feel I am doing nothing wrong by posting this. It is public record...

Steve

Does this look like the Lar/Mar PPIMV to you?

Cool, thanks for the verification. :thumbsup:

nice, that looks like a very nice build you got there bra bra (d-cup)

Aloha DB-- :rock:

I can't wait to get this thing. Payment is sent and then off the amp goes to Jerry.

Anyone know where I can get a replacement plexi front panel that goes to 11??? It would top this off nicely.

Another surprise Goodie... I had dibs (For a long time, now) on a buddies GMW, that I will also be getting soon.

Thanks Kage

WOO HOO, if I have this all for the next gig-- I am REALLY going to have a "BLAST"!!!

Yippie, the payment got there today and he's sending off the amp tomorrow. \:D/

I also ordered a New Plexi Panel that goes to "11", w/ the added touch of adding a ZP MXI (Mod11) the left of the power switch. ANY creative ideas on that, or do you guys think I should leave it MKII or Blank OR???

Some More pics the seller sent me:

Cool. I got an amp I bet you would love to check out. It's basically a copy of a 68 50 watt plexi with a switchable all tube boost. Very brown.
Aloha,Rob.
