Ibanez - UE400 and UE405

Sorry, I haven't been back to this thread in a long time, @zsetlan. You could try and solder directly to the pins then shrink wrap them to keep them from shorting out...

I actually modded one of mine using a ribbon cable soldered to the inside of the connector and brought out to a 5 position dip switch.

Dr. Bob-
I recently acquired 2 ue-400s, neither of which has a switch. These have really taken off in value - going for $500 ish on reverb and eBay- I digress

My switch for my ue 405 works with them but I’d rather have dedicated footswitches for each.

My question is could you build me 2 of your switches?! And what would you charge? I’d pay shipping on top of our negotiated price.

I’m reasonably handy with a soldering iron but don’t have the time nor more importantly the space to attempt such a build....

Thanks!

Hello!
A few weeks ago I got back my original UE400 by chance, which I had in my first band in the early 80ies. As expected, it didn´t work, but it seemed that the footswitch was the problem. In search for a new one I found this (super!!) thread (thanks a lot!!) and was encouraged to repair it. With jumpers I found out that the effects unit and the small circuit boards inside the foot controller were working well. So I decided not to make a new footswitch but to replace just the push buttons.
The ones I found fitted nearly perfect. I only had to file the original holes to a round shape and used the screw nuts of the old buttons as washers (filed/grinded away the thread), because the body of the new ones extended too far into the box and touched the circuit boards.
One wire of the push button I soldered to the “SW“ hole (where the original red wire was soldered), the other one to „GND“.
I don´t know if this would be road-proof, but for my home use it works perfect.
The new buttons are mady by Tru Components (Great Britain?) distributed by Conrad electronics here in Austria. They switch 48V/2A which is far enough and are sold as „vandal proof“. So I expect them to last a very long time.

I got a UE400 in for some issues; those issues were dirty position switches that after a cleaning were functioning properly

This unit got the distortion section. I couldn't find any schematics anywhere, so I traced it.

As you can spot the TA7136 chip is prominent in this unit.

EnjoY!

I'll add some pics on my instagram later!

I have one here found for 5 euros at a charity shop without the FS. I thought about making a new pcb to retrofit instead of the original connector one, using a 9 pin parallel socket (old mouse type). That would allow the original one to be put back in if required, and would allow a DIYed fooswitch to be made as seen above.

Or this (which can be a good start), don't remember where I got this... Would require some pins to be made, but still...
