Roland Recent Questions, Troubleshooting Help & Support

If you buy a second hand, it may have been damaged in mini switch (tact switch) under the WRITE button. You need to replace the tact switch. Easy and inexpensive, you can do yourself, only with a little knowledge of soldering . Tact Switch: You may also try the FACTORY RESET. Restoring the GT-10 to the settings made at the factory is referred to as a "Factory Reset." Not only can you return all of the settings to the values in effect when the GT-10 was shipped from the factory, you can also specify the range of settings to be reset. If you do this"Factory Reset", all the setting on user memory (that you create) will be erased, so backup your setting before doing this steps. For more detail on "Factory Reset", read the GT10 user manual: roland.com/support/article/?q=manuals&p=GT-10&id=1810803

It seems that when you engage the recording mode, the RC 3 draws too much power and resets itself. Does it work on battery power? If so, then I'd check the power connector for good fit and for corrosion, and I'd check the adapter for proper voltage, polarity and current. Do you have a "PSA series" AC adapter? If not, then check the fine print on the adapter you have for Output, and make sure it's 9V and also that it says 100mA or higher. The Boss PSA can output 500mA and can usually drive 5-6 pedals with the right breakout cable. And I suppose you already have this, but just in case you want to RTFM: Boss RC-3 Manual.pdf 8-)

If it is a drum machine, why have you posted this query under Cameras ? You may get more help posting it under musical (and I use the term loosely) instruments.

Make sure there is not a switch that makes it output to external speakers.

Well it could be a sereis of things. First of all, check compatibility with your opperating system, if that is ok go back to the Korg website and re-download again.

Go to "YouTube" and type in "Roland FP8 piano repair"

If the PSU is a switch mode type it is clearly faulty but if it is a transformer type checking it open circuit or off-load will usually result in a significantly higher voltage than specified. In order to check the latter type it is necessary to first apply a load approximately equivalent to the device it would be powering if the device was working normally. Sorry I can't answer the rest of your question...

I have the Boss ME 50. Here's things to try. Use wall outlet to power the 25 instead of batteries. Have volume on amp up, volume on pedal all the way up, volume pedal all the way up(depressed), no gain on amp(use clean channel or clean setting if only 1 channel)effects on amp off(reverb, chorus, delay, boost, etc.) mid range knob below 5. only 1 pickup on, guitar tone knob all the way towards treble. If this puts you in the ballpark you can then make slight tweaks to any of these settings. What we're trying to do is not run a dirty sound from the pedal board into an amp with dirty settings. That double dirt often causes a muddy sound. Aside from that you can back off on various effects in the patches. My 50 has a list of the patches and factory settings, so if the drive, for example is set on 8, I might back it off to 4, or the compressor, or the delay, etc. If you like the sound save it. If not continue on. Start with the amp 1st. Higher output tubes(such as JJ's produce a cleaner sound. Also the demo you heard was not coming from your guitar speaker which may not be on the clean side.

Did you check the solder connection on the jack where it connects to the motherboard? That's a high stress point and could simply be a broken contact that needs to be resoldered. Should be 3 or 4 pins likely.

Get the manual from web site and it will tell you how to replace the battery.
