Is there a good speaker level amp switcher?

    I bet a lot of you have seen that nifty little device that ampeg dealers have in their stores that switches between 8 amps and 8 speakers. It has the ampeg name on it.

    Essentially you move one knob to select the amp you want to recieve the speaker level output from and the other knob selects what speaker you want that speaker level output to drive.

    My guitar player wants to bring 2 or 3 different heads but use the same cabinet.

    Do any of you know if there is a company that makes a good/transparent amp switcher that is designed for speaker level signals besides the one for ampeg dealers?

    hey, I just thought, get a nice big double pole, single throw switch that can handle quite a bit of juice. Something designed for AC circuits. Then build a box with a couple of inputs, and one output with a switch between them. You will not want to do any switching with the amps on, AT ALL. You could cause some fun fierworks that way. If you aren't sure how to wire this, get someone to build it for him, like me. I could do it for a bit of a charge. But tell me what you think.

    it is only for dealers to use for testing multiple amps with multiple cabinets. It really helps with demo-ing products. So, like I said, ask you guitar player if he wants one built for him. Won't be fancy, but it'd work great.

    I would just build one. You can get a suitable DPDT switch at Radio Shack, even. Build it into a sturdy metal chassis. Don't use 1/4" connectors unless they're the kind that are insulated from the chassis.

    This will work if both amp outputs are solid state.

    If you're talking about siwtching between amps and cabs WHILE THE AMP IS ON you need a heck of a lot more than simple DPDT switch if you expect the amp to survive for long.

    No you won't, as long as they are solid state and the DPDT switch is a break-before-make type, as most are.
     
  13. If you're running tube amps into one of these "switchers", the amps not connected to the cab better have the appropriate resistive load on them somehow or your you're gonna lunch a bunch of amps in a hurry.
