Morley ABY Switch

Simple set up. Used with a JCM2000 and Orange Rocker in stereo configuration. Now I use this pedal to switch my POD X3 out of the loop with the Orange amp. No complaints.

Very quiet and clean. No issue with 60hz hum. No noticeable degradation sound quality.

Rugged steel case. Switch came loose after initial purchase. Easy fix, just had to add the lock-tite, tighten the nut down and I was good to go.

Didn't have to deal with customer support.

Solid, simple, and one of the lesser expensive pedals I found on my weekend Guitar Center binge. I have seen it listed on the GC web page for $60 but if I recall correctly I paid $30?? The advertised price is pretty high for a simple device like this.

Gripes.. I had to mod it. (Though I mod everything...)

I like to leave my rig setup and ready to roll. Cables must be unplugged to disable the LED's and will drain the battery down over a long period of time. I added a toggle switch so I can turn off the indicator lights.

I'd rather use 9v batteries for something else. 9v is overkill for 2 LED's anyhow. Replaced the 9v battery with a double A holder that has a connector for 9V hook up and changed LED 12k resistors with 3.6k to compensate for voltage difference so the unit would light up nice and bright.

LED's are the same color. In the dark, sometimes it is hard to differentiate between the 2 channels. I changed the color of LED 1 to yellow.

Overall: I like the case, and I like the switches and connectors. The unit is solid and you can smash the hell out of it. I would imagine you'd need to give this little box hell to bend the case. Advertised price is a little high so HAGGLE.

I like it and use it everyday.

It's easy to hook up, but if you want the LEDs to light up, they could do a lot to improve the battery access. Once you get the screws undone, you still need a screwdriver or something to pry off the back panel to get at the battery hookup.

I noticed a barely noticeable drain off my top end when I hooked this in line with my . There were no pops or anything. I tried it in several spots in my signal chain both before, after and in my new skb pedalboard, and depending on the configuration I had it in, it either slighty increased my background 60 Hz buzz off my strat or had no effect.

Only used it for a couple of weeks, but no reliability issues.

Didn't need them.

I can't compare it to other ABY switches, but if you want to run a signal into either of two outputs, or vice versa, I think this thing would do the job pretty well. Are there better boxes out there that do this? Probably, but I haven't tried any others out.

Extremely simple to operate.

Absolute garbage. I attempted to use this to switch between/combine 2 amps. Signal bleed, obvious tone degradation. Why bother, when you can buy an ABY from a dozen other makers for not much more?

If you only use it as a tuner mute, it is acceptable. But then... why use a big, heavy ABY box for a tuner mute? Heck, buy a Korg Pitchblack tuner and enjoy the true bypass.

Mine seemed to work fine, seemed solidly constructed. Many of the reviewers below had bad experiences. I couldn't keep it long enough for it break down.

No experience. It seemed to work as intended, so I saw no point in contacting them.

I play loud rock & roll, for about 35 years now. The rest of my rig is probably irrelevant for this review. It seems to me that an ABY switch ought to do one thing only, and do it flawlessly. For $50, this is terrible product. For 50 cents, I'd use it as a doorstop. Sad.

This thing makes a loud *POP* when you change channels!
I have eliminated everything from my chain and this is the problem. If there is signal going through the amp when I change channels get a really loud pop and the other people in the band look at me like I am crazy for doing on purpose.
I agree that is does not affect the overall tone a significant manner. I just can deal with the pop!

I emailed tech support and they said it was working fine and the do not guarantee these against popping when channel switching. At least they emailed me back.

Don???t buy this and get a better aby box!

Pretty straight forward pedal. Pedal works great and is built like a tank. Very nice, smooth switching. No manual, it is not needed.... I do wish the battery was a little quicker to change, but that is hardly nothing since it is not required to use this product.

I am using this to switch between a Peavey 6505+ and a 79 Fender Vibrolux. I mainly use a Peavey Wolfgang guitar, and sometimes a G&L Tele. And sometimes A Peavey 5150 combo. In any combonation, this pedal works great. It is very quite and has a nice smooth transaction between amps. I don't hear any "extra" noise from this pedal, just the normal hiss from a "high gain" amp.

Have only had it for about a week, but like all Morley products, it is built very well. I would not consider having a backup.

Don't know. Haven't ever dealt with them. Seems pretty nice though, I have seen some of their people post on here.

I looked at some other A/B boxes, I liked this one because of the 1 into 2, and the price was great. I would replace it if it were lost or stolen for sure.

I rated sound with 5 because there is a noticeable sound degradation due to the signal leakage through the 100K resistors that links the positive signal to ground in each channel.

I just cut the Chanel A 100 k resistor (NOT THE 12 K RESISTOR THAT RELATES TO THE LIGTHS) and I received in that channel a total clean signal, with no loss of tone of any kind, that I feed directly to my mesa bogie amp.
I left Chanel B without modification because I use effects in that channel that obviously alter my tone.

Good Luck

I bought this pedal to replace my Boss A-B switch cause the Morley has 2 switches. One controls either A or B and the other controls A& B on or off. I have two effects loops running into two amps. I like this switch. It came with no manual but a little info on the box is all you really need.

This is very quiet. I have 2 loops on my pedal board. It all starts with my SKB pedal board, my Ibanez Weeping Deamo Wah into my Fender Tuner. Loop A has a Boss Noise Suppressor, Marshall EVH Compressor, and a Boss Overdrive OD3 pedal. Loop B has a MXR EVH Phaser 90 , and an Ibanez 808 Reissue Overdrive pedal. I use 2 different tube amps. One is my Peavey Windsor Single channel 120 watt amp and Cab and my other is a Peavey Valve King Combo amp 100 watts into my Marshall Avt. 412 cab.

I have read some of the rewiews that said that it was not reliable but I have not had any trouble with it. But I am not heavy footed either. Any switch will wear out if you stomp on it. I feel very strongly that I could depend on it in the long run.

I've not had to use it.

I have been playing for over 20 yrs. and I try to buy things that I will use on a regular basis. I have 4 guitars presently. I own a Gibson Premium Plus guitar, An Epiphone Ace Frehley Les Paul, an Epiphone Tony Iommi SG, and a Takamine Acoustic, electric. I play late 60's to late 80's Rock and Blues. The only thing I wish it had was a plug to hook it up to my pedal board. I hate to change batteries.

Works great, it is a very simple unit. I use it to switch between to amps and one guitar with effects pedal.

Crystal clear like it isnt even there!

never failed me and I bought it used

I called them regarding an older model of this to find out some differnces with the new and they were very helpfull

It is exactly waht I wanted. The only thing is that the led stays on unless you unplug the input cable. It would be cool if they found another way to turn the led on and off.

pretty easy, doesn't come with instructions, but if you need instructions for something this simple how did you ever figure out that you can get a switch to run one guitar through two amps or one guitar through two amps?

No noticable cut in sound quality. I've heard of popping noises, but i didn't have any. (i use a Vox ac30 and an Orange ad30 head)

BROKE IN A MATTER OF HOURS! GLAD I DIDN'T MOUNT IT INTO THE PEDAL BOARD! SO PISSED!

Didn't bother calling, I'm bringing it back. Should have never happened. considering I didn't sue it that much seems senseless, they have already lost my trust.

I give it a 1 because stuff needs to work. End of the story, and I barely did anything to it and it broke.

Easy to use with one caveat. The equipment you're plugging into this thing should all be high impedance meaning at least 20 k ohm resistivity at all frequencies. The reason will be told below.

If it's working, okay.

Out of the box, I noticed the same thing other people did. I tried to have two guitars go into a single amp, and the level dropped considerably. I sent it back to Morley, and they replaced the 10k resister to 1 meg and the situation improved considerably. 10k is too low of a shunt to ground in my opinion. Many pickups have impedance in 47 k range. 10 k will eat up about 30% of the voltage not counting the amplifier load (assuming amplifier input resistance is very high). 1 Meg resistor should be the standard. I haven't used it long so I don't know about reliability at this point.

Morley was very courtious. One of few manufacturer who actually have a working customer service in my opinion.

I have a serious problem with the owners manual. It shows that you can use this box either as two sources to one output or one source to two outputs. It only talks about not connecting a speaker wire to it. Okay, then some may try to use it as a combiner for two effect devices. Big trouble. The outputs of the two effects devices will short each other out. It probably won't destroy them, but it sure won't work. Owner's manual have no warnings about hooking up two effects devices in this manner. I was tempted to use this box in this manner, and checked out the schematic (good that Morley have them ready on their site) and I found out about this.
