    I need a good AB switch that is made with quality components and is completely undetectable in the chain. I can't find one. I'd be using it with 2 basses into 1 amp so this should be simple, right? I've been throwing bills around at an alarming rate to get the rig I've always wanted and now I'm hung up on a filthy AB switch?!? I've been to harmony Central to find out about the usual suspects, but all seem to have short comings. I'm anal. I need a GOOD, simple switch with quality inerds, not and EXPENSIVE switch with fancy features that I won't use. Any suggestions?

    No experience with AB's but if you had to, you could always hit the speaker/tuning mute on your amp (if there is one) and unplug. Last resort, maybe.

    Yeah I was looking to do the same thing you are, I just gave up and got the TU-2 and use it as a mute.

    Normally, i would say go to loooper.com but that dude is outa commission so i just went with the above option.

  5. By that I assume you mean no tone alterations? Avoid active devices in that case.

    What are the shortcomings of the ones you've looked at?

    If you were me, you'd buy yourself a Carling 3PDT footswitch, a small diecast box, three quality jack sockets and make it yourself. Trouble is, with anything mechanical like that you might find that it pops audibly when you switch. This is not the fault of the AB switch itself though.

    Other devices in the chain often don't like having their inputs or outputs momentarily disconnected, capacitors charge creating a DC offset, then when the switch reconnects the signal path the DC offset is very quickly shunted to ground creating a thump or pop.

    exactly, I'd say building one by yourself is not that hard.

    I had and now currently have a Morley A/B/Y. Has never failed me and has no pops. There is one for sale in the classifieds for about $25 as well.
     
  10. I also use the Morley. No worries.
     
  11. Loooper is supposed to be nice. Can be customized any way you want. You can do an A/B and add a mute, or a tuner out, etc.

    The web site says the guy is really sick right now and not taking orders until he is better. Cool stuff. Real simple.

    Try the Radial Bigshot A/B switcher. Its only about 60-70 bucks. I have the Bigshot effects looper and its excellant quality, readily available and cheap.

    ABY Selector Added to Radial's BigShot Series

    October 7, 2005
    New from Radial Engineering is the BigShot ABY, a guitar amplifier selector that lets the player transition between two guitar amplifiers on stage for tonal range.

    The Radial BigShot ABY is extremely compact yet built with 14-gauge steel to handle the most abusive environments while providing added stability on the floor and reduce sliding. Two footswitches are prominent on the stepped top surface: the first is labeled 'toggle' to select between the two amps for typical A-B switching and the second is labeled 'both' to activate both amps at the same time.

    The BigShot ABY is equipped with four 1/4" jacks: the input that connects the guitar; a tuner output that can drive a tuner, and two outputs labeled A and B. Output B is equipped with a switchable isolation transformer that eliminates hum & buzz caused by ground loops. Also, once engaged, the polarity reverse switch becomes active allowing the player to line up the two amps in phase. A ground lift is also provided to further reduce hum and buzz problems.

    I have an ART AB/Y that I use in my guitar rig. I like it. If the Y part is important to anyone, then the Radial is a good bet as it has the ability to reverse the phase between A&B. Sounds nutty but some amps are reverse phased on the input so this might be a help in a two amp scenario.

    +1 on Loop-Master. They make an amazing array of loopers and A/B swithces. Simple designs with good quality components at good prices.
