Fender jumpering 101 - basic question

I know some of you have seen me with several questions concerning jumpering a Fender DRRI.

One thing I've noticed is it seems like every time I ask, I get a different answer about how which input jack to use for each part of jumpering.


So... does anyone have some pretty basic things to say to help me understand how to choose which input jack and which channel to do jumpering?

The DRRI and other Fender Blackfaces have 4 input jacks:

- Normal 1: for lower input signals
- Normal 2: for higher input signals
- Vibrato 1: ditto
- Vibrato 2: ditto

I usually play a humbucker guitar. So if I want to jumper channels...?

- Where do you plug in this high-output guitar?
- Which two jacks do you use for the jumpering cable?

.... Or does it *even* matter... so long as the jumpering goes across channels?


Cheers,
-- Joe

Plug them in every variation that you can think of and find out which sounds best to you and has the versatility that you want . . .

BTW, are you sure that your amp channels are not out-of-phase? . . . I though that if the amp had a Vib channel then they would be olut of phase and in order to not have cancelation of juicy frequencies you'd need to use a pedal like the Launch Pad or some-such?!

Yep, they are out-of-phase. The primary thing I'm trying to do is use the Normal channel for most of the dry guitar sound, and the Vibrato channel for the reverb. If the normal channel volume is much louder, you crank the reverb up pretty high, and change the tone on the vibrato channel, you can alter the tone somewhat to minimize the phase cancellation.

But not completely... so I'm trying to see if any of my existing gear can help me do the trick of inverting the phase. I have a MagicStomp and a Boss LS-2 line selector... they might be useful pieces in this puzzle.

Thanks,
