    If I want to run my Bass through two amps at the same time (and the amps only have a 1/4" instrument input jack) is there some sort of 1/4" splitter I need to get. I was thinking of just getting a Y splitter from Radio Shack but I read something that made me think this isn't the best way to go. :confused:

    Edited to add: Any links to products that would solve my problem would be appreciated. ;)

    What did you read?

    In order of price:

    Y splitter cord
    A/B Box (some have built in nosie gates etc)
    Rackmounted audio splitter

    HTH

    What I had read was that by only using a Y splitter cord that it is possible that one amp could draw almost all the signal leaving next to nothing for the other amp.

    If you have an active bass, then a Y splitter will work just fine. If you have a passive bass, it will work, but the sound might not be to your liking. If you are using a passive bass, then it would be best to use some sort of preamp or DI box before the Y cable.

    what two amps are you planning on using? does either of them have a tuner output? Most times the tuner output is only mildly affected by the amp, (sometimes not at all). many times i've taken a line out of the tumer output of amp # 1 and run it straight into the input of amp # 2

    another option if you're just looking for more power/volume and you dont care about using the tone of both amps is totake the effects send of amp #1 and plug it into the effects return of amp #2. Some amps have a hotter send than others, so you may want to try it both ways. If only one amp has an effects loop or line out you can always lug that into the input of the second amp and keep the gain on amp #2 way down. There's always a way.

    Does one of them have double input jacks? If so, those are usually paralleled internally, so you can just run a cable between them. It’s electrically the same as using a splitter.

    It's a passive bass. Any suggestions for the preamp or DI box?

    if all those amps have are one front input a peice and outputs you'll be best off with an a/b/y pedal (that's an a/b pedal that lets you run to both amps at the same time). Get a cheap one. Only because if your amps are as limited as you say they are they probably arent so hi-fi that they need the most expensive a/b/y box out there.

    There’s really no reason to get a switchbox. It’s the electrical equivalent of a “y”. Just get a “y” with a single male to two females and plug it into the first amp. Plug the guitar into one end of it, and run a cable from the other end of the “y” to the second amp.

    I have used one of THESE Rolls passive 1:4 1/4" mixer. If you just use a radioshack splitter you might get some funky electrical cross talk between amps which could prove harmfull to one or both amps. thats been my experienc, at least it did sound a little funky. you can use the mixer to split an output OR put multiply inputs into ONE output. resistor values of the mixer to lower the signal strength a little , but the flexibility is nice.

    Your stereo effects out will work fine - I've been doing that for years through a Boss SE-50. You'll have to check your patches though - some will chorus just one side and pass a straight signal to the other. Personally, I like that, but I'm sure you've got your own preferences... ;)
