The A B Switch debacle

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?
 
completely undetectable in the chain

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.
 
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.
