Hey vlad/amp modders, pre-PIMV vs PPIMV / other mods

[cyndicate]

So I grabbed a built Metro 100w plexi '69 superlead spec for sale over at TGP, I put in the Lar-Mar PPIMV into it and everything works perfectly, now just deciding what else I can do to hack it up. Figured I would fuck around with modding this one and order another one to build from the ground up soon.

I'm reading a bunch of stuff over at the metro forums but there is so much crap to dig through, so couple quick questions..

PPIMV vs Pre-PIMV - what differences would I hear putting in a Pre, also if I want to convert from the PPIMV to a pre which schematic should I use, the one that is on the 2203?

What are some common mods to add more gain to it so I can maybe do a search over there?

Is there a way I can make a switchable mod that switches from a 2203 to a Superlead stock?

I also keep hearing about a 1959/RR mod, what is that?

Thanks!

Will

Yes go for the Master on the 2203, i find the pre-PI Master sounds better especially when you start adding gain I'm not a fan of the PPIMV at all...

Im no expert by any means but I have been reading alot about the mods you are referring to over at Metro.

RR mod is basically the "one wire" mod. Basically cascading gain stages which adds a ton of gain. Haven't attempted this one yet, but will in the next few days or so.

You might want to look up 1959/2203 "Neil special" in one mod. Looks pretty good and reasonably easy to do. I have the layout for it here on my PC. Pm you email and I'll send it over to you.

For the pre vs. post not sure which would be better. I currently have the PPIMV installed and it kicks all sorts of ass.

Hope this helps...

I use both masters in my amps, and the cathode following MV is cool as well. You can do a stock 59 and 2203 switch yes. Like a DPDT mini switch in there. SDM over at metro has cool drawings for you.

I like cascading the bright channel into another bright channel which is similar to the RR and one wire mod. You can get high gain by changing the tube that has the tone stack. check out the ultimate tone books by kevin occoner to.

I just found the Neil Special layout on the Metro forum, need to figure out what is actually going on before I attempt it I'm hoping I can return everything back to stock if I fuck anything up I kind of wish I built this from the ground up now to figure out what I am doing

Is there a thread over at Metro that I'm not seeing with a list of layouts/drawings in one single thread?

EDIT: Nevermind, Just found out they are in his signature

Did you order a kit yet? Which one did you decide on?

 

[jerrydyer]

was his friend Tony Alamia ?

 

[jerrydyer]

should be called Park Mod

A lot of people don't understand the idea behind the PPIVMV aka Rich Mod. I am good friends with "Rich" and we laugh about people not liking it...only because they never knew the story behind it. In the early 80's Rich played in a bunch of bands (including Overkill) and he was looking for an easy way to get Priest tone or Maiden tone, Accept tone etc. So Rich asked a friend who was an electronics guru for help. His friend came up with the PPIV master (which had been done before and they never claim to have invented it). The PPIV master works perfectly to get the Priest, Maiden, Accept tone without having to bring a ton of gear. Heck, all you really need is a head and cab

When Rich was on the Les Paul forum he heard people talking about ways to get that tone without going deaf, so he told them to use the PPIV master. After that, people started to call it the Rich mod. So a big reason why a lot of people try it and don't like it is because they don't know the idea behind it To me, it is perfect for getting Priest, etc tone and not having to do a 20 minute sound check. It is NOT good for everything though...

Whats difference between the Rich PPIMV and the Lar-Mar PPIMV? Are they pretty much the same?

Hey Jerry, where do you buy parts for DPDT switches and pots? Also for any other parts like resistors/caps?

 

[jerrydyer]

www.cedist.com
www.antiqueelectronics.com www.tubesandmore.com

mojo and metro etc

 

[cyndicate]

Also for a superlead, is there any difference between using a Y-cable and jumping inputs?

 

[jerrydyer]

yes sir. I think the difference has to due with the 68k 's in parallel the answer to that is at metro. I lower my input grid res to 33k anyways so I think thats what is being accomplished. Not positive. Im only 80% cork sniff.

Very cool, thanks for the info Dave!

I should have worded that statement a bit better... I'm not a fan of the PPIMV when you start adding more gain in the preamp section too. I personally find the PPIMV to sound ok in a stock Marshall like a SuperLead, but i prefer the Pre-PI Master if you're cascading gainstages. Better still i much prefer the CF Master to any other type, but the Pre-PI Master is great too with a few extra tweaks

 

[dstroud]

come on Will - be a man! take out that mv and it'll be the last mod you ever need to make to that amp !

Wish I could! My neighbors would hate me, they probably do already

Haven't' ordered one yet. Thought I had my DSL50 sold and that didnt happen, so I'm toying with the idea of doing some mods to it that Mike Fortin suggested. Just not sure it's going to change the amp enough for me to keep it. I installed a choke on the DSL and it made a huge difference at band volumes, but still not the tone I am after.

Seems like everytime I get close to getting the funds for a kit, my family sucks them up for something else. Very frustrating...

So now that I know the idea behind this it will sound better?
