How do you play through both channels?

ryokan · September 8th, 2007, 05:18 PM

I have an Ampeg Gemini I, and I would like to try to play through both channels at once. How do you do this? Do you run a jumper from one channel to the other? The amp has two inputs (guitar/accordion) for each channel, so do you plug the guitar into channel 1, then run a jumper from accordion ch. 1 to guitar ch. 2? I don't want to do anything that will fry the amp -- so, please let me know -- thanks!

Yes you just jump em out.

You can do it several ways but try this for starters.

Plug your guitar cable into the #1 input for Channel one then plug a short cable into the #2 input for Channel one and plug the other end of it into the #1 input for Channel two and there ya go.

Thanks Red Planet! I'll try it out.

if it sounds really thin and awful, it dfoesn't mean anything bad -- it just means that the two channels are 180 degrees out of phase with each other, as most (all?) Fender amps with reverb are. No idea about the Gemini. I have a non-verb Deluxe and I do this trick once in a while but really, it doesn't sound to me like it makes a huge difference.

Works well with tweed amps and Marshalls, give it a try. Worst that can happen is like KC says, the two channels are out of phase and it sounds thin.

HI
I've got a Ceriatone Marshall 18 watt Clone. It's got an EF86 channel with one input and a second channel with hi and low inputs.
Could i jump these channels also?
Thanks

I gather the Barber 'Launch Pad' pedal is good for out of phase amps and /or channels, as it has a - ve and + ve output from the one input. I wanted one for a perfectly clean boost and buffer - and found this 'extra' function whilst researching.

It may be deemed an expensive solution to a simple problem though...

F.F.

Just try it and see if you like what comes out. The tubes don't matter. Every tube stage inverts the phase 180 degrees, so if the two stages end up in phase, everything is fine. If not, everything may be fine anyway, I know of at least one guy who jumps the channels on a DR and does interesting things with the phase cancellation.

Jumping channels is a no-brainer and you're not going to make the amp explode. If the amp does explode, then there was something seriously wrong with it anyway. Don't ask whether or not you should do it, just try it and decide if you like the sound. If yes -> you have something useful. If no -> no harm done, just unplug the cable.
