signal splitter ?? Using 2 amps simultaneously

Basically I am looking for a way of splitting the signal from my guitars so
that I can play through 2 amps simultaneously.

Any suggestions on how to do this without degrading the signal would be
appreciated.

Thanks

I used to use an Ibanez stereo chorus pedal, but there are many pedals
that would do the job.

Often, "stereo" delay or chorus pedals are used for this purpose. One side
gets the "dry" or or unaffected signal, the other side gets the "wet". If
you just want to use the two amps, set the delay times and/or modulation to
zero, and both sides get the same thing.

Erm... I do this a lot, but not quite as you describe. I use a stereo chorus
pedal as a splitter for 2 amps, *but*:
- with the chorus off, both amps get the same signal
- with the chorus on, each amp gets one side of the *stereo* chorus

I think the clue is in the expression "stereo chorus"... ;)

This thread got me sufficiently interested that I did a bit of checking. The
Boss DD-3 seems to work as Patrick describes - one output is clean, the
other processed, so if the effect is turned right down it will act as a
splitter. I've recently got interested in delays, so this could be the
choice for me, or the DD-5, in which both outputs seem to be processed.

I used to have a (homebrew) splitter box that allowed me to switch the guitar
to either of 2 amps or both simultaneously. There must be similar things
these days.

Using both amps with the vibrato set at slightly different rates gave a great
Leslie sound (this was in the pre-effects days!).

Good luck, I hope it's successful. Fortunately they cured mine with a

Maybe I'm being thick here (what, me?) but I read in the OP's message the
desire not to degrade the original signal. Wouldn't running through a chorus
pedal with the effect set to zero have some degrading effect on the signal,
unless it's a 'true bypass' situation? Isn't there a 'Y' shaped cable thingy
that would simply leave your guitar or last effect and split into two, to go
into the two amps inputs? Do correct me if I'm wrong ;-)

Doing that would reduce the input level to each amp and I think that's
what the OP didn't want to do.

Possibly. Forget the Y cable though. The OP needs an AB or AB/Y box,
should cost too much either.

An ABY box is your best bet. Morley do a Tripler pedal which also has
a boost so you can fix signal loss. However I'd recommend Redonion
solutions http://redonionsolutions.co.uk/ and get the transformer
Isolation circuit built in. As running two amps can cause ground loop
problems.

You will pay extra for the isolation circuit but it would be well
worth it. I run two amps without it and get some noise so I'm thinking
of getting the seperate boxes for that.

Yes, I had the same thought.

Either buy or make a Y cable.

It doen't reduce it to any noticeable extent, not with high input impedance
valve amps anyway, my switchbox was just a fancy Y cable.

I bought a little 2x3 Aluminum box from Maplins , 3 jack sockets , and
made one . Dont get me wrong it never went to plan , i had 1 jack as
the input feeding my 2 output Jacks , i just fiddled around until it
all worked , and you cant blow anything , had it all done in maybe 10
minutes total . I still have it , and a great little gadget to have in
your kit bag .

Another option is a pan fader. It's like a volume pedal, but heel is on
amp, toe is the second amp, and in between is an infinite mix.

A guitar pick up is a power source and will only produce a certain amount of
current. If you use a simple Y splitter the current to each amp will be
less than it would be to one so the voltage generated across the amps input
impedances will also be less. If your amps have plenty of gain this
shouldn't be a problem and it's the simplest and easiest way to go.

Alternatively, you need a buffer. A unity gain voltage follower will do the
job nicely for very little cost if you can solder a chip on to a piece of
veroboard. A TL071 op-amp is ideal (FET for high input impedance) running
off two 9V batteries and you'll find a voltage follower circuit at
http://ourworld.compuserve.com/homepages/Bill_Bowden/opamp.htm .

The coolest way I've seen to do this is with an Ernie Ball Pan Pedal.

All the way up is all one amp, all the down is the other and anywhere
in between.

Mike McCready from Pearl Jam is set up this way.

Toe down all Marshall
Heel down all Fender

Why would it matter if you got it exactly in the middle?

Oh, come on now Chris. You know we guitarists are a finicky bunch.
Things must be "just so." ;^)

I like the amp-blending idea, but my brain couldn't tolerate another
pedal like that. The volume and the wah are enough already. Also, at
somepoint I would want *more* of the toe-down sound, and so I'd "turn
it up" by rocking the pedal away from it.

Now someone (I forget whom) made a boutique amp that was a Fender
Deluxe Reverb on one channel, and a Marshall Plexi on the other. I
don't remember many of the details, but I think there was a pedal that
rocked side-to-side somehow; and you could blend the channels
together. Predictably, it was very expensive.

I thought the original post was 'using 2 amps simultaneously' - to me
that meant kind of a 'stereo' thing.

And, I think it would matter to the sound guy :)

Why?

I'm saying that when I tried to use one - it was HARD - LIVE - to get it to
go back to the middle easily... It was like trying to have a wah stop dead
center...

Why would it matter to the sound guy? Because if he was trying to maintain
a consistent level, and you didn't park it in the middle - he'd have to
compensate... Surely - both amps would be miked...

I had MUCH more success with Boss AC-2 pedal.. Sent my cleans to FOH, and
would turn OFF my amps.

That's my experience.

I can get roughly to the same 3/4 spot I usually park it on for rhythm
without too much effort.

That's what sounds checks are for. You would set the levels of the two
amps in the FOH sound and monitor mix, prior to taking the stage.

T...@pedalboards.com can build exactly what you need, as well as various
parallel, serial, stereo, etc. pedal boards systems. I have one of his units
to be used to bypass a Fender Reverb when it is not in use (the FR affects
the dry signal even when "off" locally). It is of high quality and it works.
