Calling all technically unchallenged people (stereo rocket)

[Reeltarded]

I think I am going right side PT with OTs in center front, output tubes along back edge and preamps along left edge. Yes, left edge in a row.. Think about that for a second. i need to think a lil more. The configuration will be like building a reverse layout with the tone stack broken out towards the front edge of the board and the stages along the left edge.. I think.

Sounds like it should have a board with the pre & PI sockets mounted in holes thru the board.
You know it makes sense.

Only kidding - the board will be in & out like a fiddler's elbow.
Don't do it.
Would be interesting though...
Harr Harr !

It's going to got to have that 4 varistor M'gnatone 480 wiggle snot thing.

How about the 3 tube fender vibrato circuit?

[Reeltarded]

Fender vib doesn't do anything like this one. This thing is singular in the wiggle world.

Player upper left (requires flash) go down the list to the song Bills to Pay. That is the Magnatone in stereo making the underwater Mentos commercial sound. Lil 417 and a 450. I want this amp to do as the 480 in true stereo.

[Gibsonman63]

Interesting concept. Just my two cents, but it be cool to keep one side completly dry and have all the effects on the other side. Then you could always cut through the mix and adjust the effects to taste, maybe have more clean headroom on the effects side.

[Reeltarded]

If it were chorus I would so totally be with you, but this thing is magical, the 480 model. The 450 and 417 are sort of as you say and still very good at it, but the 480 is over the top awesome. If it works like that, it works!

If it doesn't I have unused triodes and this thing will become a very time consuming drive amp.

If you can't find those rare parts to build the original circuit, the Nicholas Boscorelli fx book has a solid state implementation of that vibrato circuit.


Here's an old Stompboxology article on various implementations:

I'm working on sourcing some new production varistors suitable for the Maggie circuit. I've a quote coming in a few days. If there's enough interest and the price and parts are right, maybe others would be interested.

I'd definitely be interested in a couple of sets if the price isn't too bad.

You know, what might be interesting is stereo spring reverb, and routing each side of the vibrato circuit to the opposite sides reverb. That could be trippy (and no, it's not what, you're thinking, even though it's legal here now).

Put it in a V-front combo like a Watkins Dominator cab.

With 4x10's.

In a furniture-finish cherry cabinet.

You could leave it in my living room when you got tired of lugging it around.



All kidding aside. I used to play a stereo rig, and I always got pissed at the sound men, who all seemed to hate stereo. They'd mic one side and right before the gig started I'd unplug the mic.

I'd be the only one in the band who's sound didn't get worse as the night progressed.

Having two tubes for reverb sounds like trouble though. Even thought of what a modified long tank does with a pair of pickups then it only takes 3 triodes to run the reverb... but with stereo wiggly and output.. tube count is starting to get as out of hand as the current requirements.

Everytime you add a tube you end up with an unused triode and then the plan turns to amparchy...



It does anyhow, but I am blaming unused triodes.

Yeah on the stereo rig and house mix. Most rigs weren't all so stereo out there. Booyah. Mix to me!

[Colossal]

You know the rules...NO. UNUSED. TRIODES

[Reeltarded]

I have one unused triode that was a second CF for a couple days once. I am thinking about making that stage a parapallelled stageeded so I don't wear out a tube and throw away good triodes.

[martin manning]

I spent some time looking at the Magnatone 480 schematic and came up with the attached description and block diagram. The thing is pretty crazy... I mean, 13 tubes? Including a vacuum rectifier? Plus a Ge transistor?

[LeftyStrat]

Seems you could lower the tube count by going with SS or digital for the LFO and associated circuitry. Digital would allow not only additional waveforms, but you could vary the phase difference between the two vibrato channels. Another thing is a switch to add in the original signal to get stereo phase shifting as well.

Signal path could still be all tube, though I might compromise on the reverb driver and make it SS also, using something like Craig Anderton's Stage Center Reverb.

At the other extreme, just a single Rocket preamp with the unused triode as a mono CF send, and another two triodes as stereo returns into stereo power amp would keep it simple, then you could plug in any stereo outboard gear.

You could build a standalone stereo vibrato, as I'm sure it could have other uses in the studio. I wonder how it would sound on vocals.
