Completely straightforward perfect product. Great sticker space right in the middle!I bought this so that a friend’s guitar playing can be plugged into an amp or DI box as A, and my modular synth system as B. He will be able to play through amp; synth, or both. We haven’t tried this yet, but I was disappointed to open the clamshell and find one of the rubber feet is devoid of any adhesive qualities and sliding around inside the packaging. Granted, that seems like a small complaint, but now I have to make a special trip to go find some feet so the battery cover screws don’t scratch my wood work (play) surface. And it’s hot as hell out there right now.I tried applying a small dab of water, but the adhesive wouldn’t “activate”. Having to add an item to my to-do list because of a brand new product deducts one star right off the bat, in my book.Very poor insulation. Very noisy. Not going to use. Get a better one.Simple switch that works well. Only reason it needs a battery is for the LED lights. Works well without one.I have seen the same type of product for 2-3X the money-delivering the same results. I waould say a good deal.I like fender, but this product is noisy. I did a few tests to ensure it's the switch pedal. I am returning it and may look for different product. I gave 5 stars for sturdiness, but noise issue makes it useless.Simple enough design but causes a buzzing sound during play. Not sure if they all do that but it is annoying,Exactly what you would want from a basic A/B switch. I use it often and it never fails. Has two inputs into one output OR one input to two outputs. Also the two sides at once.This pedal did not seem to work, particularly when running two pickups or two guitars in for one output. What I eventually realised was that you had to switch A&B off by clicking again after using it, then A or B switch would work as expected. As there are no instructions, I found this by trial & error- nearly returned the pedal as faulty. With two guitars and volume control, leave both controls wide open & control gain elsewhere, as each volume control controls both guitars so it seems. Not sure if tone controls are affected, will have to do more fiddling.OK this is a very cheap pedal. It works fine and lets you either connect 2 guitars to 1 amp or 2 amos to 1 guitar.It’s made of metal, but the fit and finish are really poor, I opened the panel to fit a battery for the LED lights, one of the 2 screw holes is stripped and the screw will not tighten. There is glue all around the four rubber feet, and still one of them fell off.Not sure whether or not to keep this, depends on whether I can find a better built ABY pedal for a reasonable price.Been looking for something like this for ages. Really great splitter. I use it for alternative effects channels.Input to outputs - either A, B or A&B. Lights let you know what you have on. (unlike cheaper splitters).Battery (PP3) or 9vDC supply. (Can work without power but you'll get no lights.)Solid, well made. Good for studio or stage. No hum or noise or loss of signal.And I love the fact it's a Fender too as my guitars of choice are Fenders. Nice red.Everything about this pedal is good, except for its size. It's the same size as a TrueTone Route66 OD and compression 2-in-1 pedal. (Or an ibanez tubescreamer TS808 deluxe), which seems excessive for an AB-Y. Rugged, well made, good switching. LEDs for each option so you know exactly what's going on. One switch does A-B toggling, the other kicks it into Y mode. Really versatile. Works passively, but needs power for the LEDs to work. all the cables are top mounted which helps get it onto pedalboards, but seriously, in this age of mini pedals I'd be amazed if they couldn't make this at least half the size, if not more. Now, if you want it off-board as as standalone, eg for switching instruments, then this is great, and its size/sturdiness make it excellent for this. I have 3 of these for various uses. Nice bit of kit.Yes, this pedal could be a bit smaller, but the quality and value for money is great. Really sturdy and the optional LED lights are handy. You can use this passivly (without power) but without the LEDs, but it might get frustrating to know what you have got selected or not.I'm using this to plug 2 guitars into one amp, so I can change guitars quickly between songs. There are smaller boxes out there, but if like me you want to add this to your pedalboard, be aware of the jack socket orientation. Many others have sockets on the sides and as the other ones I looked at had the AB inputs on the left side, that interfered with my pedalboard chain and took up a lot more space. This one has all input/output jacks on the top, so it worked better for me...Anyway - It does exactly what it is supposed to do. Very happy with this product.
