Question about Roland Mobile Cube Battery-powered Guitar Combo

Open Question

Hi, My Roland Mobile Cube at times when playing stops working and I notice the light showing the power switch has been pressed is no longer on. So I believe one of the wires to power switch needs to be resoldered. I need to know the correct way to open this so I can repair it. Thanks

    This unit does not have a pushbutton switch. It turns on with the volume potentiometer. This unit is not serviceable. The handle has rivet type fasteners that go through both the front and back plates and through the handle.

SOURCE: Roland DP-2 pedal not functioning correctly.

There are two types of damper pedal switches, on that is closed until you press it, and one that closes when your press it. It sounds like your Casio is expecting one type and your Roland pedal is the other type. A quick way to test this is to plug a guitar cable into the Casio pedal input and see if the keyboard sustains. If it does, then your Casio requires an "normally closed" switch.

Some pedals have a small switch near the cord or even on the bottom of the pedal that will reverse the switching operation (BOSS pedals, a division of Roland, have this feature). If you can find that, then change the switch position and you should be OK.

If not, and you feel like digging into your pedal, you could take the bottom off of the pedal and check out the switch itself. Many pedals use a switch that can be used either way. The clue will be on the switch itself. If there is an extra tab on the switch that is unused, then switch the wire that is furthest away from that tab to that tab. This will probably involve soldering, but it is nearly impossible to damage anything.
If moving the wire that is furthest away does not do anything, then try putting that wire back and switching the other one.

If your pedal does NOT have an extra tab, you're SOL, unless you want to buy a replacement switch (unsure of make). If this is the case, you are probably better off getting a different damper pedal - preferably one that is marketed as "universal"

Check the fuses. There is probably one on the outside of the amp and some inside the circuit board.

That is the first thing to check. They are most likely inside the circuit board. Remember to replace them with the same voltage and amperage ratings.

Roland street cube won't power on due to battery acid leak


Most likely the acid ate the internal power supply, but if you can dis-assemble it and clean any trace of gunk with a toothbrush and electronic cleaner, including the fuse and it's contacts, maybe you'll get lucky.

Roland cube street water damage repair


What part of it got wet will determine the course of action.

If the whole unit were submerged, the unit may prove more time consuming to try to fix than to locate a used one. However, I have salvaged imersed laptops before. the procedure is not much different- make sure the unit is as dry as you can possibly make by blowing a fan on it for an extended period of time.- Days.

Once dried, use some contact cleaner on the jack contacts and interupts, any manual control and any switch.

You can then apply power. If nothing lights up, check and replace fuses as needed. Also check the power supply board for failed caps or rectifiers.

Once the power supply is known to be functional, systematically check the LCD display and the aspects of the amp that it controls. This board will be the most vulnerable and most likely to be the source of most issues you will encountr.

If the display survived intact, and amp does nto work, apply a signal to the inputs and trace the signal through the amp with a set of headphones set up with test prods. The problem will be where the signal stops.

I need to replace the power push button, but do not know what part number it is. Trying to get it ordered through Mouser, but there are too many listed. All I know is that it's an Alps switch, and it reads...


HI,

I've just had a Roland Micro Cube amplifier in for repair and it uses the same type of Alps switch you mention. ( It's also broken )

This is a simple single-pole latching push-button switch, so electrically, almost anything rated for an amp will be good enough.

Alps no longer make the same part, so you'll need to find something which looks the same and fits the original hole.

My repair is easier, because the replacement part doesn't have to match anything.

Graham.
