Looking for Real Life
well, this is a cheap & easy way to run 2 amps at once, I figure SOMEONE must not know how to do it

you need 2 instrument cables, a guitar, and obviously 2 amps

run cable 1 from guitar to input 1 on amp 1
run cable 2 from input 2 of amp 1 into input 1 of amp 2
turn them both on & bam, 2 amps at once

Or spend 40 bucks and get a nice little ABY Switch, then you can choose when you want to link them up. But, what you say will work, unless there is a phase issue between the two amps.
 
Re: i just learned this, you probably know it but

That sounds cool, but not all amps have 2 inputs...

I never would have thought about that though, very cool.
 
Re: i just learned this, you probably know it but

well for bands with 1 guitarist it'd help a lot, even at low volumes, with little 1x12's, the room is totally FULL

true

sometimes, you have to lift a ground
 
Re: i just learned this, you probably know it but

You could also spend 5 bucks and get a 1/4" splitter from radioshack.
 
Re: i just learned this, you probably know it but

That's the same thing people have done on plexis and bassmans for years as far as jumpering the channels to each other ...except here you are doing it to two amps instead of two channels in one amp ... also depending how the multiple inputs are wired it causes some loading on the guitar signal as well, like i said, depends how they are wired. What you are doing is running off of one input jack in parallel ... also most effects with a *hardwired* tuner output enable the same exact thing, it's just a paralleled connection off the input jack (note: not *all* tuner outputs are done this way ...JSYKIYDA).

So, I guess I shouldn't tell him about the reverb throw trick huh? Or using a volume pedal to swell the reverb ... or both ... nah, didn't think so ...

The guitarist in my brother's old three-piece band used to run his guitar into a stereo delay pedal set for a very short delay, then run the left and right delay outputs into two 1x12 combos (one either side of the drums). It sounded HUGE! :approve:

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.

i don't think that would work for me

I'd like to get my hot rod deluxe's reverb working on the bassman aswell, but it's not footswitchable
 
Re: i just learned this, you probably know it but

The simplest way to run two amps,is just to have a stereo time based effect as your last pedal and split the outs into two amps....Both amps end up with the same wet signals but only when you kick that stereo pedal in..

Re: i just learned this, you probably know it but

but once again that takes money

the only pedals i have are distortion pedals

yet i have like 10 cables lieing around

Yes....It does suck to not have money....

Re: i just learned this, you probably know it but

if you just wire a 3 way switch to 1 input jack and 2 output jacks you're set....right?

Well, depends on the pedal output, as some do a dry/wet thing per channel, instead of a phase inverted effect+dry on one channel, and an effect+dry on the other. Even so I see what your saying, it still only sounds *mono* when the effect is off. For giggles try the reverb throw trick sometime, the reverb control via volume pedal is a nice live thing to have up your sleeve as well ... the other thing is more a recording trick.

Yeah, you'd have to do a bit of rewiring, unless you have a line out or effects send, or DI that the reverb happens to be sent thru, it would still contain the direct (dry) signal, but you could swamp it, and control the level thru one of the bassman's channels ... but then again, you'd be tying up one channel on the bassman and you get more depth if you daisy (jumper) the channels together. Of course you could always run into a Y split, run one side into one channel set louder, and the other into an overdrive (or whatever) and then into the other channel set lower to get the sound of your pedal's distortion mixed with the natural overdrive of the amp ... wouldn't be stereo, but hey more depth.
