I, for one, would like to know. :smoker:
The reverb throw involves making sure both amps are grounded correctly, same power strip and ground switches correctly assigned ... better yet replace the two prong vintage cables with three prong modern plugs (for the vintage amp guys) ... If you use a modern amp with a 1/4 reverb jack this makes it easiser, however those Fender RCA jacks can be used as well, you wire an RCA jack to a 1/4" phone jack (or cable), you run the reverb end (where the footswitch normally plugs into to shut the reverb off) to a cable and connect the cable to an unused channel in a second amp (or whole amp for that matter). Then depending where your reverb knob comes into the circuit, it either does or doesn't have any effect, you turn up the second amp, and voila' *most often* the main amp is now dry, and the second amp only has the reverb signal itself ...dry on one side, swamp on the other ... listen the the middle section of Zep's Whole lotta love on the vocals ... a similar thing going on in places.
The second is even simpler, wire that reverb jack to a 1/4'" cable and run it to the output jack on most passive volume pedals, set your amp reverb control for the max amount, and turn it down with the volume pedal, if the pedal has a minimum volume control you can even set a normal reverb level and swell the reverb into swampish/atmospheric stuff. The pedal performs the same job as the on/off switch, except it's variable in between full on and full mute. Just becareful when you try it out, I can't swear that every amp is wired the exact same way, keep channel volumes off and bring them up slowly for the reverb throw trick, it cool because the reverb has a bit of delay in getting to the other amp anyway ... great stereo trick.
