running two amps together...

scoots · February 1st, 2008, 11:03 PM

i have a deville 212 and i'm looking at picking up a peavey session 500. i want to run these two together. one gentleman on the tdpri suggested getting a passive id box to run these two together. a guy at one of the local guitar shops said i could run the second amp out of input 2 on the first amp and plug directly onto the second amps input. if i use a passive box am i just using the first amps power supply? i want the power off the session 500 as well, that's what this is all about. suggestions? (had to do it jh!)

Get an A/B/Y Box simple as that.

Using a DI box your sending the preamp and the poweramp signal to the Session 500 as your coming out of the external speaker jack. You have to have the first amp speaker working too so you would run out of the external speaker jack into the HIGH input of the session 500. Then if you set the volume on the Session 500 and what ever tone settings you want the volume control of your deville will run both amps volume Turn the Devile up the Session volume will go up as well. This works well but like others have said you could run a A/B box and set up both amps to run. Like I said Daisy chaining amps I have heard with onboard Reverb can cause issues maybe some one can clarify that.

Just run a cable from input 2 on one amp to input 1 on the other amp

it's cheaper than a splitter box, that's for sure.

Wouldnt that depend on the amps I have read about issues with Reverb amps having ground loop problems or out of phase with each other can anyone explain that better> I have heard that amps with out Reverb there is no issue with this.

You may not have to lay out the dough for an A/B box but it is nowhere near as efficient or user friendly.
If, say, you are working and you decide you want to use only one of the amps for 1/2 a tune or something you are yanking on chords and playing the situation when all it takes with an A/B is a stomp of the foot. This is just one situation.

From my experiences, the second amp never seems to put out it's full potential when you do that. Get an A/B/Y and both amps will perform at their best. Someone here with more knowledge than myself can explain why that is.

A/B/Y boxes are generally pretty cheap.

The problem you speak of is internal when jumping the reverb channel to the non-reverb channel on the same amp. They are out of phase from each other, (caused by the addition of the reverb circuitry)so you get some cancellation between them when you do this. This doesn't happen on non-reverb amps as the two channels are not out of phase with each other.

I do find an A-B-Y switch to be useful when using two amps at once, as you've got a few more options available by being able to hear each amp separately and together with a touch of a switch.

I have a Morely Tripler that also adds a clean boost to make up for the loss when you split the signal, and you can run a third output to another amp or a tuner.

Thanks for the Clarification on that. I still have had good luck using the DI box to amplify the sound of a tube amp through a stronger SS amp for more amplification. But then I am not looking to mix the signal of both amps I am only looking to make my tube amp signal louder. So I suppose there is merit for all the methods depending on what you want to do and accomplish. Jim

I don't know others, but my Digitech Delay pedal has two outputs... you could try using the second output on your last effect if it has it.

+1 on daisy chaining the two amps with a simple patch cord.
What that does is connecting the two amps in parallell just as an A/B/Y box would.

If you're looking at "picking up a Session 500", I'd recommend getting a weightlifting belt on first so you don't injure yourself! (I use one for pedal steel, but I DREAD carrying it any time it gets played out - 90 pounds!)
