Ampeg V-4B Ultra-Lo switch

Discussion in 'Amps and Cabs [BG]' started by Dave M, May 5, 2006.

  1. Anybody know where I could find a replacement for this? fliptops.com doesn't carry it. Seems like it's a pretty unusual multi-pole rocker switch.

    I'd like to use the same thing to keep the panel unmolested, and the multiple hookups to it seem to dictate a direct replacement.
    Anybody got a spare lying around? Or maybe a dead amp that's a good donor unit? :D

    OTOH, anybody ever open one up and repair or recondition one?:meh:
  2. Try Ampeg service. Ampeg is having those switches manufactured for the SVT-VR. I'd imagine it's the same as in the V4B.

    The ultra lo switch was pretty much the only thing on that amp I never used. I heard that the rocker switches were completely unavailable until they started making them for the VR like the previous poster mentioned. Ampeg is a good suggestion. I did have my V-4B worked on because it was humming. It was a major PITA but that may be due to the tech I chose to take it to. It sounded better after it was finished though.

    Service is a good idea.

    I am not 100% sure they are the *exact* same, although the outside appearance is pretty close.

    But, I think you may have to wait a little longer, since I don't think the parts have percolated through to Service yet. It usually takes a little while after the first shipments.

    Hmmm.....a V4B with the ultra-low switch on. Can you say "Threshold of Farting"?
  6. Externally, they look a lot like the same from the pictures I've seen. I hadn't thought of that. I'll try the Service folks and see.

    I hope that'll work. I haven't had any luck so far.

    Yes, yes I can. :D
    It's not so that I can engage the circuit, but so that I've got a relaiable switch regardless of position. I keep it off, myself, but the contacts are a bit dodgy. That bugs me. ;)

    Thanks for the help so far. :bassist:
  7. I thought I had a contact for some NOS or good used ones, but couldn't find it. If you can get the switch apart without destroying it, a pencil eraser will clean off what DeOxit won't. Sorry I couldn't be more help.
  8. Thanks PBG. I have thought about the possibility of disassembling and cleaning the contact areas -- if possible. Not sure about its chances yet.
