Help! Scroll down footswitch is unresponsive!

grell6954

Help! The scroll down foot switch on my GNX4 is unresponsive! Most of the time stepping on it does not induce the preset number to change from a given number to a lower one. Every now and then pressing that footswitch works to decrease the preset number, but seldom.
The foot switch next that that one, for increasing the present #, works fine. So does the circular by-hand knob for changing the preset # up or down.
This problem means that at gigs to decrease the preset number I can't use my feet but have to bend down and use the circular knob to decrease it. What a pain!

I just had the GNX4 in the electronics shop to fix the recording mode-it needed a new card-reader port/input. If anyone has had any experiences with the foot switch problem I've described and can suggest anything, please let me know! Of course I could just send it back to the shop (AmericanTV) and I would guess they could fix it, but maybe I'm missing something simpler?

Thanks!

I've heard of this happening, read posts on it. Do a search, maybe you'll find some answers. Usually it seems to be the sensor behind getting old or dirty or whatever; there's guyz here who know how to open the unit and check. I have no idea, I'm just here to meet chix. :roll:

I can help you with this one - happens to me too :evil: But don't worry - its nothing terminal!

I've had most of the push buttons on my GNX3k stop working at one stage or another - I'm talking about the major footswitches, the effects buttons, the lot. My unit is about 2yr old and all these buttons went in the space of roughly 3 months. The last to cack itself was the stompbox switch just last weekend. Just because they stop doesn't mean they're stuffed. In the case of mine its always been a dry connection on a switch so take the top of the unit off (mine has allen screws), power on (don't touch the circuit board!) give them a hit with a good quality electrical spray lubricant (one that doesn't attract dust) and work the switch on and off till it starts working again. Has always worked for me.

In regards to what causes it in the first place my tech said to think about where you store your GNX, could be heat, lack of humidity, dust, the angle of the moon in relation to uranus or what brand of guitar lead you use in it ..... whatever, all I know is its a pain in the you know whatta when it happens.

Hope this helps.

Leave it to shredd to go looking for girls in a place where guy-to-girl ratio is about 1000:1

Perhaps you guyz are forgetting - where I live, the ratio is 10,000:1 :shock:
And the \"one\" that's here is Hereford-ratable... :?

Thanks doods! I'll try out the suggestion of taking off the top and giving the switch a good blow with a lubricant (hey get your mind out of the gutter! We're talking effects boxes, not... oh well).
I'll let you know what happens.

Hey it worked! I took off the top cover allen screws, then the bottom phillips screw to get inside the GNX4. I had purchased a control cleaner-spray for electric circuits at Radio Shack for about $10. One spray had no effect but after two there was some responsiveness and after a third application of the spray to the trouble area (under the non responsive footswitch which controls the 'down' motion of the preset #s) it was working fine. I gave it one more spray for good measure then closed it up . The GNX4 seems to be working fine now.

Great easy fix job which only took about an hour and not a lot of $$!

Thanks again. Now I wish I could find a spray which made my guitar playing sound a little closer to 'mucho goodly', but I guess I may have to wait for the next generation of me.
