So I bought a Joyo JF-30 AB Switch. It can be used in reverse so I can A/B guitars into one amp which is a bonus. It also functions perfectly well without power so what is the point of having the ability to be supplied with power?<br />

Does the power or battery run LEDs so you can see what mode you are in? I have an A/B/A+B pedal/box that works this way. I use it when I run my guitar to my Leslie, a one guitar two amp setup.

No idea if the power is only for the LEDs but it makes sense.<br /> <br /> I have a Boss AB switch which has unreliable switching, making it frustrating to use, and doesn't function without batteries (I guess because it's electronic switching), and isn't set-up to accept external power. I gave up using it way back in the late nineties. The Joyo seems to be a sturdy, less finicky and more versatile cheap replacement. Time will tell, I guess, if it's reliable or not.

An A+B mode would be very handy. Didn't think about it when I bought the Joyo.

Hey Modal.<br /> I have an old Leem A/B box that works like your Joyo. It's completely passive but requires a 9v battery to power the LEDs only and also has no DC input.<br /> <br /> I think it also does A+B, but it's been a million years since I used it so can't be sure.<br /> <br /> Don't know I would have a use for it these days but 'spose it's good to have in the gear box.<br />

I only bought it 'cause it was so cheap and probably won't use it often. I have used it today for A/Bing two guitars and two amps. It's really good for flicking between gear while the memory of what was just played is fresh and is much better than changing cables.<br /> <br /> Never really knew why I bought the Boss back in the nineties, maybe to experiment. Anyway it became moot because it has a dicky switch.

Years back I had bought a Planet Waves A/B box. It was extremely noisy so it was returned. The one I'm using now I purchased from Taylor of all people. I've had it for years and see they no longer offer them. Works well.

I had a Whirlwind passive A/B/A+B box. It had some noticeable signal loss. So, you might A/B your A/B box! See if a guitar straight in sounds the same as thru the box, with and without power.

Some A/B boxes use MOSFETs to switch channels; these are dead quiet (no click when you step on the switch).
