Zoom A2 Effects processor Cant remove circuit board

I cant remove the main circuit board. There are 2 layers of circuits and the main one (largest) can only be accessed from one side. I've removed the obvious screws, nuts etc. and it appears to be fixed onto 2 metal supports. Do I force it off these or is there something I've missed.

After removing one knob carefully, you might find that there are nuts and washers holding the pots in place and the pots are soldered to the second circuit board which is held in place by these nuts and washers.

How can I mix the sound of the Zoom A2 and the dry sound of the guitar?


the easiest way to mix less effect sound and more natural guitar sound is to reduce the level of the individual effects within the patch selected. The more challenging method would be to go through a splitter box 1st, or any stereo effects box, to split the signal, and then you will have 2 outputs, one dry, one through the Zoom. The 3rd (and simplest ) method would be to place the Zoom in the effects loop of an amp that features a send / return balance adjustment.

Bank up button short


okay. (I've experienced this myself). There is a small On/Off button on the circuit board below the stomp pedal. You have to open the unit to change this out. if you have any experience soldering this will be no problem. Now the button you de-solder, take with you to any local radio shack and match it up. check for number of pins that go in the circuit board and height of the push button. (i had to super glue a small piece of rubber to mine so it would reach the stomp pedal). and just replace it with that. Your problems will be resolved. and note these buttons go out frequently depending on the use. its most annoying. Good luck!

Zoom g1x dc supply not working, my zoom g1x is working when battery operated but if i connect it to a adaptor there is no power, i've already checked my adaptor and it was properly working, what can i...


Is the unit old?? Is it stored in an environment that has temperature fluctuations?? It could be the terminals on the input of the unit have dry jointed. This is when the solder lifts away from the circuit board. I have had the same problem on my ZOOM MRS1608 recording desk. Resolder the connections on the input. The base plate will problably remove easy enough to get to the point where the adapter is soldered onto the circuit board.

Good luck

Crate flexwave 120 tuner and all effects stoped working


Hi there,I have the same problem with my flexwave 120. I opened the amp to measure several capacitors on the small effect circuit board. If one of this capaciters have internal short circuit, wich will effect the others causing effects to fail. I removed them one by one to find possible short circuit. All capacitors were ok. I think the problem is in the processor wich is to diffucult to replace. I think it's easier to replace the effects circuit board. But where do we find this board??10_29_2011_6_25_35_am.jpg

I need to know step by step how to hook up my entired system using my macki board. I have a Mackie 1604 Vlz, a power amp for mains, a power amp for subs, a crossover, a vocal effects processor, and a 16...


ok, first thing will be the effects processor. look for the "aux sends" output jacks near the bottom center of the rear panel. run a 1/4 inch instrument cable from "aux send" 3 out into the input on the vocal processor, and run another from aux 4, if the effects processor has 2 inputs. then, from the vocal processors output, run 1/4 inch cables back into the "stereo returns" on the mixer, (located on the rear panel on the bottom, extreme left) 2 outputs per input, since its making stereo effects. so, if you ran just send 3 into the processor, you should have a left and right return instrument cables into the mixer for "stereo return" 3 (left and right). if your processor has 2 imputs, and you are using both "aux send" 3 and 4, then you will have to have a pair of cables going to each "stereo return" for 3 & 4. -to apply effects to a microphone(s), you would adjust the individual aux send levels for each channel you want to have effects, and you would have to ensure that the master aux sends and returns are also turned up..

ok, the snake is simple, each xlr (3 prong mic) connector on the snake is labeled, so, just plug each xlr jack into the corresponding channel on the board, and plug the first 2 1/4 inch ends of the snake into the "C/R out balanced" outputs on the board, located on the rear panel, up and to the left a bit.

at the stage end of the snake, ues a 1/4 inch instrument cable to copnnect the first 2 1/4 inch jacks on the snake to the left and right inputs of the crossover. then, from the crossover, connect the sub power amp to the "low" stereo outputs of the crossover with instrument cables, and connect the main speakers amp to the "high" stereo outputs of the crossover with instrument cables. if its an adjustable corssover, you will want to have it crossed over somewhere about 80-120 hz to allow only the lowest frequencies to the subs.

now, from the amps to the speakers, we ane going to have to use heavier 12-14 gague SPEAKER CABLES, instead of light gague instrument cables. hook the subs up to the stereo speaker outs of the sub amp with speaker cables, and do the same for the main speakers.

I have a Zoom 9000 Guitar effects processor, and although I have its original adapter, and although its red light flashes and power is on after plugging in everything, I could not get any sound from my...


I'm a Zoom 9000 owner (since '93, I think) Did you try batteries only? Are you plugging the guitar into the "in / power" jack and not mistakenly using another jack? When you plug in the guitar, in to the Zoom 9000 does the window come on with the settings shown? Sorry, I know some of these are obvious but always the chance of us being human. If all that seems fine, then I would read though a manual to see if maybe it is a setting problem, i.e., sound somehow got inadvertently turned off. If you don't have one, an internet search will lead you to one. Sorry, wish I knew more.

No power


There is a possibility that the receptacle for the adapter plug has one or more broken solder joints on the circuit board.
