Re: AB-boxes

I don't understand why you guys are having this problem. I use a Marshall 900 combo with a 69 Super reverb. I use a Morley A/B box. Not sure which one I can run either amp or both at the same time and I don't have any issues. My entire setup is wired with GeorgeL cables, and my pedalboard is powered with a one spot using a daisy chain that I had to splice. I have a DOD box running through the Marshal effects loop, and I have a Boss CE2, DD3, and a TS9 runing through the fender. All this comes together at the A/B box. In front of all of this I have a Vox Clyde McCoy Wah, and a Matrix tuner. It runs virtually silent aside from the Hiss of the overdivr in the Marshall. I think I would try some other A/B boxes. I have using this setup for a few years, and am very pleased with it.

Re: AB-boxes

I have been using the Morley ABY pedal and never had the grounding problem. I am running through a Furman power Conditioner as well, s o that may be why. A pal of mine uses the Switchbone and swears by it. I have to concur. He uses a Fender Twin Amp for cleans and slight overdrive, and a old JCM 800 for his brown sounds. The Marshall HAS to be cranked to get that sound, so it was hard to match the sounds. The power boost circuit in the Switchbone enabled him to push the Fender harder without having to alter his tone and kept them closely matched. Just another suggestion. i know this pedal weighs in at $229, but it certainly solved his problems and simplified his rig. Priceless!!

I do something like that except I use an A/B-Y and a volume pedal between the box and the amp. It lets me re-adjust the second amp on the fly when neccissary. I like to run one amp wet, and the other amp dry. I use the volume pedal to adjust the amount of dry signal present in the mix.

Re: AB-boxes

I have a Morley and I ran into many of the problems you guys have talked about. I am not sure how some of these ABY selectors work, but one thing for sure is that they can work good with one amp, and like crap with another. Plus, at least to my ear, it sounds like they mix the sound of one amp with the other, when both channels are activated. What I mean by this is I can hear the preamp of one coming through the preamp of another. Even running seperate cabs. I am not sure if the signal is mixed at the heads and sent back through the ABY or what. I don't know what the deal is there, but that is not what I want. I have noticed that happening quite a bit too. Long story short if you want to get rid of all that crap, use a selector system. I downsized my rig and I have a selector for sale in the trading post. It is a GCX and GC (GCX Guitar Audio Switcher an Ground Control). The uses are almost limitless and it works like a dream. Next time you are getting ready to do a solo, and you are doing a pedal dance, you'll wish you had one of these babbies. Ok, I think I have tried to sell it enough. Haha! :laugh2: Yes, dude you need some type of switcher.

Re: AB-boxes

I doubt that there is anything wrong with the ABY-2 or whatever they call it,
without seeing a schematic of the internal design of the ABY-2 and the amps I really couldn't say ... a lot of AB boxes do not ground the input of the other amp, so it's input is sitting there with a cable plugged in the the end of is effectively hooked to nothing.and the Y setting is going to split the voltage evenly betwwen the two amp inputs. Another way of doing such is what I did with two identical amps (same model), I ran into both amps at the same time, one set distorted, and the other set clean, I A/B ed between the two preamp outputs which Y'ed out to both power amp inputs, both amps plugged into the same power conditioner. A side from a slight click it worked flawless, that approach might not work well using two different amps as you are dealing with two different power amp sensitivities (one amp winding up being louder than the other). Open up the ABY-2 and trace it's circuit, then you'll have a better undertanding of what's going on there, then you;ll be able to see if you can fix the situation.

that problem was solved three days ago, but, thanks for the advice, anyway. I'm thinking, if it gives me anymore problems, I'm taking it back for a Morely ABY or something nice. Bye.

Re: AB-boxes

uh-oh... the day after that last post, the AB-2 stopped working... so I took it back today and traded it in for the DOD 270, not a problem and it seems hella durable.
