Simple and Economic Signal Switching Solution

MXR's M196 A/B Box switcher pedal lets you send your sound where you want it. A single input for your electric guitar, acoustic guitar, keyboard - any instrument with an audio output - feeds three separate outputs. Outputs A and B are controlled with individual footswitch buttons and can be on simultaneously, sending your guitar to different amps, while LED indicators let you know what's going where. The Throughput is always on and is great for your tuner or sending a dry guitar signal to a DAW for re-amping in recordings. Quality built and reasonably priced, add the MXR M196 A/B Box switcher to your pedalboard!

Dunlop legacy and MXR

Dunlop Manufacturing started in 1965 much like Sweetwater, a family-owned and operated company. In 1972 Dunlop introduced the MXR pedals and quickly established themselves as pioneers in the guitar effects pedal market. Their continuing innovations are highly-acclaimed, winning multiple awards with their Bass Innovations line and presenting the guitar-playing world with new classics like the Carbon Copy delay pedal. The MXR Custom Shop delivers you the classic MXR pedals made from original specs and gives you a touch of 'boutique' with special runs of guitar effects pedals. Sweetwater is proud to partner with Dunlop to give you the best MXR has to offer!

  • Route your signal to 2 footswitch-controllable outputs
  • Always-on throughput for your tuner or DAW
  • LED indicators on A and B channels let you know where your signal is heading

Does what it's supposed to do, looks sharp

Needed this to be able to shoot my MIA tele into my 65 deluxe reverb and run my martin acoustic electric into the PA. I just put it at the end of my chain and unplug my tele and plug in my Martin when it's time for a song that uses the can also work backwards, so you can put a second one at the beginning of your chain and have an electric guitar and an acoustic guitar both shooting into your pedal board simultaneously. I might snag another one at some point so I won't have to be unplugging guitars all the time. It's smaller than I thought it would be...which is nice, since I don't have a huge board (Pedaltrain Classic Jr.) Looks sharp on my board, does its job, and I haven't noticed any unwanted coloration or noticeable degradation of tone. Would definitely $...can't go wrong.

I had a gig coming up and needed an A/B-Y box. I knew I had an Whirlwind Selector somewhere, but after a week of searching and the gig fast approaching I, out of panic, bought this box. Of course, less than 24 hours later I found the fifteen year old Selector. I set up my rig with Selector and I noticed a large gain reduction from my PRS with Les Paul Modern pickups when using the "Both" channel. When I received this box I noticed no gain loss from my PRS to my Mesa Boogie MkIV. Very happy I ordered it! Anyone want a Whirlwind selector cheap?


I'm not sure what the issue with this pedal may be, but for my application this pedal makes a lot of noise when integrated into my signal chain. I use it with a tuner plugged into the through output and one channel runs into my Peavy Classic 30 and another channel to another tube amp, or a solid state PA. Either way, this pedal creates a lot of noise. When I run my pedalboard directly into my amp without using this pedal (I removed the pedal completely) then the amp is virtually quiet. I think the wiring in my house is problematic, but I have found a combination of six pedals fed into the front of my amp that creates virtually no noise, so I can't attribute this pedal's problem to the wiring. I've had to weed out quite a few pedals for this reason and this MXR A/B Box is one of them. It's now merely decoration on the shelf in my office/music room. I'll keep experimenting with it and if I find a practical use for it in a different set-up, then I may change the rating.

Nice idea . Poor execution. 2 defective boxes so far.

Didn't work!

I usually love mxr products. But I bought this and right out of the box, the output jacks were loose and it just buzzes. Piece of junk if you ask me.
