anyone stereo panning?

[mantella]

I've searched the boards and found a few good threads on this subject, but nothing super conclusive. I realize most people aren't that interested in a stereo effect for live guitar. It's a hassle. But stereo does have it's applications in recording and such.
Is there a good stereo panning scheme out there that anyone knows about?

Check it out, this one's integrated into a vibe:

Check out the 4MS Stereo Panneur. I used to have one, lots  of interesting panning in there. It's basically 2 separate Tremulus Lunes with syncable LFOs, so you can do all kinds of very interesting things with it. Also allows desynching of the LFOs.

I did some work on a submini tube based stereo panner about a year ago, though I never got round to finishing it. There's a schematic and some soundclips here: http://www.diystompboxes.com/smfforum/index.php?topic=71168.0

I am interested in this as well... for use in a live setup

Stereo panning is often less pleasant or tolerable than you might think.  People are wowed by the dramatic nature othings like the Ibanez Flying Pan, but quite frankly it is NOT a set-and-forget effect.  It is disorienting enough that you only want to use it in very small amounts.

What might make a stereo panning effect more tolerable, if it is used?  I think waveform has much to do with it.  Certainly the "turnaround" in the sweep needs to be graceful.  I suspect that a true sinusoidal LFO is gentler to the ears than a triangular sweep.  Perhaps even more desirable is use of a quadrature LFO, so that the pan is not purely reciprocal (i.e., when A is at its loudest, B is at its quietest).  A quadrature LFO woud have the two channel being modulated 90 degrees out of sync with each other, such that there is movement, but not dramatic quiet-here-loud-there movement.

I like stereo effects very much... but I just wanted to share this idea for anyone who has/will make an stereo panner...

You can get nice effects from a stereo panner even in mono!

Send L signal into a phaser, Send R signal into a Chorus then mix back to mono.
The pan will now 'tremolo' between two different effects. You can synch the LFOs using CV.

I have a small Fender sidekick amp that runs in stereo, much like the old JC-120 that feeds the wet signal of a chorus to one channel and the dry to the other.  It has a send-receive loop for each channel such that I can feed the phaser to the dry channel and have the wet chorus side go to its own channel.

And yes, dual parallel modulation is a killer tone.

I built a stereo pan pedal a while ago for a friend as a special request. RG graciously put together the schematic for me, and it can be seen on geofex.

The difference in this case, is that I mounted the circuit into an old boss wah enclosure, so that the amount of pan could be selected using the rocker enclosure. My friend uses this to pan between two different amps. 

[jessej]

yes agreed.. I forgot to say my main amp is an JC-120 and I also have an old DOD 690 chorus that is stereo just like that, modulating the other channel only and I often use it just like you described, running my old Ibanez 999 phaser on the dry channel. (looking forward to add a DIY orange squeezer in front of this soon!)
