Ways to achieve stereo from guitar

[radio]

Hello

I m about to build two identical small tube amps ,and I would like to know

which pedal(s) I should use to achieve stereo from guitar ,chorus or delay for example

or what other effect I could try . I m especially in doubt concerning versatility,

so what effect would "allow" most music styles.

Thanks for reading!

Stereo chorus is spectacular live, especially if you have a few meters between the amps.

Stereo delay is also nice, but if you use a dry/wet setup (one amp has only dry signal and one only the delay), you should have the amps a bit closer together.

Try building a splitter box  and trye different effects and settings on each amp. One amp clean, one with overdrive etc. I guess the simple answer to your questions is: experiment, the possibilities are endless.

Almost forgot the possibility to wire up a guitar in stereo.

That way I could align to chains right from the start.

Yeah, Stereo chorus sounds great "when its good". 
But yeah, a stereo guitar, thats kinda cool, but you'd have two chains of pedals to control! Depends what effects and how you use them I suppose

Radio, you're working too hard.  Just do this:

one link from 39 pages of search-results for: "stereo"

Thanks for the schem. David,never heard of this article by C.A.

I need to read the other 39 pages of results  too A.S.P.

I guess this is worth nothing on a DIY forum, but I use a digitech GSP 21 pro for this. It's a rack effect-unit from the early 90's, with great reverb, flanging and chorus. Apparently Jeff Beck uses one of these for the long delay parts. It also has a great footcontroll, and you can find it really cheap on ebay. Just don't count on getting a good distortion from it....

Neck Pickup goes to one channel Bridge to the other channel.

"Stereo" is a many-splendoured thing, and can be approached in many ways.

Some folks think about stereo as two fundamentally different parallel versions of something, as created BEFORE it hits the amp.

Some folks think about having something move around in a deliberate and obvious way when they think stereo.  The textbook case is a ping-pong autopan.

Other folks, when they think stereo, think about a fuller sound that has more animation to it.  No particular pattern of movement, just the sense of it.  Sound-field "busy-ness".

Other folks preer to think of stereo really more in terms of a simple active split that allows two separate amps to show off their personality.  It is a richer sound, though not necessarily one that moves around, just busier sounding.

None of these are necessarily mutually exclusive.

Many of the recent Line 6 Tonecore pedals are "stereo", in the sense of doing something different to one channel than the other, and often in a way that results in s systematic movement or shift across the stereo field.  I find it very interesting to listen to and certainly exciting to plan around for production purposes, but as set and forget effects it is occasionally fatiguing. And that would be a key issue: the distinction between "animation" and movement in the sound field that keeps your interest up, and periodic movement that ends up suffering the same fate of chorus pedals: up and down and up and down and...

Might be clarifying if I explain why I or how this came to my mind!

I got from my grandfather a 1960something tube amp stereo

As I m happy with my stereo hifi amp,I thought it could be a way to use it,

would be to add a stereo G5 kit that has a line out and to connect it to

the poweramp of my grandfathers tube amp.

Up to that moment ,I just have "double mono" so the effect pedals would do

the whole "stereo ".

Thanks to every contributor for his point of view!!

Neck Pickup goes to one channel Bridge to the other channel.

Some (all?) Rickenbacker guitars have jacks for each pickup; Rick-O-Sound they call it.  My strat is wired up like this, I was actually kind of dissapointed with how it sounded in stereo.   

My favorite spatial stereo effect for 2 amps is using a very short delay on one channel, it sounds HUGE.  The plain vanilla boss DD3 is great for this because it has the setting for short (<50ms) delay, and seperate wet and dry outputs.  Its really cool to hear what happens to the dimensionality of the sound as you turn the delay knob. 

It would be really fun to have a simple delay built right into a channel on a stereo amp.  I've toying with the idea of modding a JC-120 to be like that, since it has a chorus that I never use built into it already.

A totally different  stereo thing I've been messing with lately is using different distortions to get different clipping thresholds in each channel.  The Anderton TSF/ Red Llama be a good candidate for a stereo fuzz box, because you could use the extra inverters on a single 4049UBE chip for the extra channel.

Mark is right about it taking extra dedication to use a stereo  rig regularly, especially if your performing regularly at shows where you have to set up your stuff quick...

Make it an electric sitar--send the main output to one amp and the sympathetic strings to the other.

I still have to do stereo mods to my "Ricky"copy that is wired like a Les Paul.

I really like the idea of 2 different distortions,however this depends on how

they'll interact with the other players (as usual) ,but might be difficult

if you'll have to swape 2 distortions in one go.

Also the JC120 came to my mind as it might be worth a try to do a mono effect chain

and let the chorus do the stereo??

no one ever :this leads us directly to your question ,I look forward to an answer too.

Any famous guitar player that plays stereo only :Pat Metheny?

Yup, that can be a toughie, and generally it is addressed by FET switching.

In the case of things like sum/difference modulation devices like "stereo" phasers and choruses, the strategy often adopted by companies is to use a single FET to cancel the wet signal.  Since the stereo-ness of the output is a result of that same signal being sent to output mixer A and being inverted and sent to output mixer B, simply cancelling the signal kills the effect and does so in "stereo".

In the case of ping-pong boxes, you can cancel the stereo auto-pan by replacing the control signal for the two independent gain cells with a common fixed control signal.  Normally, what one gain cell receives would be opposite to what the other receives.

In both these instances/examples, though, you will note that there is no "true bypass", but rather buffer stages remain in place in both effect and cancel mode.

As for the JC120, the MN3007 output gets sent to its own channel.  You can easily get a slapback delay from 1024 stages, if you choose to disable the LFO and rig up a fixed clock rate.  Just keep in mind that the filtering on the MN3007 section assumes the sort of much shorter delay range needed for chorussing, rather than the much lower-frequency clock needed to step the BBD through an audible slapback delay.  That means you may want/need to adjust the filter rolloff to do what you're thinking of.

You can create a "nPDT" switch by modifying the "Tone God's" "Wicked Switch" circuit so the inverters drive the number of 4066's that are appropriate to your application.  As designed, the "Wicked Switch" is a DPDT and uses 4 4066 switches, so n=2.  This means you need to drive 2n 4066's.
