MXR® A/B Box

I'm loving this. I use in it in two ways: 1) I am able to route one output to an amplifier and the other into my guitar interface which connects to my computer. I don't enjoy recording with headphones so basically am using my amp to listen. I have maximum flexibility in regard to pedals. For example, if I want a tube screamer up front as I listen, I can run my guitar into the A/B, output #1 into the tube screamer and that into the amp. Output #2 can go into my interface which is a dry signal. If I wanted the tube screamer in both signals, then I simply do guitar to tube screamer to A/B box and then both signals have the pedal. 2) I have multiple amplifiers and this allows me to play thru 2 amps at once. I just love the "wall of sound" by using 2 amps. Again, same flexibility as before. I can run pedals before the A/B box and both amps will get the signal from the pedals. Or, I can have each amp utilize different pedals by going guitar to A/B box with each output going to different pedals and then out to the Amps. All in all, this A/B box is great. Signal is pure and it just works. Hope this helps :) Jason

This is a simple pedal that's made solid. Feels like it's built to last. Positive feedback switches click nicely. Lights give visual confirmation of which outputs are active. No signal loss evident. Ultimate versatility to use 9 volt plug or use battery. Love this pedal. So what's weird about it? Well, the "output a" jack is directly above the "output a" switch. That makes sense. But what's above the "output b" switch? The input jack. Take a look at the product photo and you'll see what I mean. It's a weird "brain scramble", especially if you're hooking up in a hurry. Still, this is a great pedal.

An Outstanding Product! Thank You MXR!

I really like this box. I play cello in a soft rock band and most of the time I can't hear myself when the other musicians get going. With this box I am able to pass my signal thru to a tuner so I can get a quick visual check of my intonation. The box has an A and B output (both switched) and a separate direct output (not switched). You can run any combination of the switched outputs. If you are hot and want to drop out of the house, you can hit the foot switch drop out. I have had to do that a couple of times when the band was silent. Once you could hear the switch "click" in the sound system and the other times you could not. It is built sturdy and battery life is fairly long. I've been running off a battery for over 10 hours with no issues yet. I cannot hear any noise introduced into the system...but that's me. Maybe someone else could hear some introduced noise.

No active buffer. Little pricey for a simple aby. Replaced with JHS active aby

Excelente desempeño. Tal como lo imaginaba. Envío rápido.

It’s works very well. The only problem is that it makes my amps buzz. Had to return it. I can’t have that happening

Pedal chain finale to tuner, DI to my audio interface, and Amp. Works fine with no noticeable degradation. I should get another one for quickly switching between a guitar cord and my 1/4 in wireless thingges. The lights are bright! I like how the tuner gets to stay on all the time now

Bien, hace lo que dice.

Excellent pour jouer sur 2 amplis en même temps si c'est là votre souhait. J'enlève 1 étoile car des potentiomètres pour régler le volume aurait été très utiles.

Works great switching between amps and combining them! Reliable mxr.

Works perfectly, both A and B can be used separately or at the same time

Ottimo
