Radial Engineering Tonebone Bigshot ABY/Y MKII

Used to have problems with ground loops while playing in stereo, the noise was just unbearable. Since I purchased this well constructed metal chassis pedal everything works as it should, not to mention that both amps work in fase now. It's smaller than it seemed in the photos which is nice to save space in the pedal board. No power needed unless you want to know where you're at, and in that case the LEDs let you know if you're playing A, B or both amps. Probably the most robust pedal I have, I'm very happy with it! Highly recommended if you play in stereo!

I love Raidial gear. Just found out about them and this is my 2nd piece in the last few months. Like the JDI this piece just does what it should in a really solid and clear way. Split your signal to A or B or have both playing. I just tried with vocals through 2 little amps for a live show and it worked perfectly. Its passive so you dont need power (unless you want the LED). It's a bit on the heavy side but still small. I can tell it's going to last for years. Solid, easy, small = Great.

I use this for a wet/dry setup.

pro:
isolation is key
gnd lift and phase switch

con
none

easy to use 10/10

This thing works as it should, with no hum or noise when using two amps together.

Of course, its a versatile ABY switcher with lots of uses, but personally I bought it to combine two amps in a wet dry rig, and "oh boy" what a sound. If you never heard two amps working together, I suggest you do it whenever possible! The pedal is of topmost quality, the ground and the phase switch are essential and work perfectly, and I am most happy with my purchase!

Excellent to exchange quickly between my two amps because on stage I used two main different sounds AC30 for clean and acoustics and Fender Greenback for rock sound.

Not sure what to review on this. It works as intended, and it helped get rid of some ground loop hum. Great bang for your buck.

I use this to split my signal to a dry and a wet amplifier, so the ground lift and isolation switches are necessary to avoid ground loops and unwanted hum in either amplifier.
Costs a bit more than other alternatives, but the build quality and added switches make it more than worth it.

+) Build quality. I don't expect this to give up on me anytime soon.
+) Great added features to a simple ABY concept. (tuner out, ground lift, isolation and phase swap)
-) Higher price. But justified by great features and reliability.

I needed an ABY switch and juggled between this and the cheap Fender ABY switch. Somehow I decided to buy the one that was three times more expensive, just because the switch is more than likely to never break.

Didn't know why I would ever need a ground lift or isolation feature, but it definitely came in handy when I bought a second amp and plugged that into the pedal system. Massive amount of interference and fuzz kicked in, but with a push of a button, all noise disappeared!

Great tool if you use two amps. Compact size, sturdy construction, and it needs power just to lit the LEDs! The only thing I don't understand is why the ISO mode (which enables polarity inversion and ground/lift) is switchable.. to me it would make sense to have it always on. But it's just a small detail.
