Roland Boss Gt-10 Guitar Effects Processor Gt10 Open - Answered Questions & Fixed issues

The first step would be to re-initialize the unit. Here's a link to the process- BOSS Support Knowledge Base GT 10 Factory Reset Initialization

what is your question? if not working, you have to open the device and find out where it is not connecting (broken solder joint? bent or worn out contacts? wire off?) and repair. or if beyond repair, order a new part.

Julio, If you already changed power supply and no success, it is probably a bad solder joint on board. I will post a link below that may help or you can try a forum. http://roland.com/support/article/?q=manuals&p=GT-10

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

May I know, what kind of damage?

There is a small chance it "could" but more likely you would just overdrive the input stage to clipping. You can try it- you need to keep the viltage input to the amp at 1 volt peak to peak or less, or you run the risk of clipping. You should use shielded cable, as you may also pick up other noise along that cable.

Check for intermittent connections of cables. The vibration of turning it off and on MAY be fixing a poor connection. Verify the problem exists using new cables. Intermittent problems are tricky to find so we have to do tests to narrow the possibilities.

The half-way cord is the clue. Read up on unbalanced and balanced lines and TRS connectors.
One of these requires TRS connections and the signal is being carried on the RING of the TIP-RING-SLEEVE connector. Plugging in half-way the TIP touches the ring pickup contact. The emgs one MAY use TRS type cables and there may be a reason the signal and hot of these are reversed. If I could find schematics on all this equipment I could unravel the exact cause. You could make an adapter with a Stereo 1/4 inch plug and a 1/4 inch jack by wiring it to swap the tip and ring between them to use for connecting to the emgs guitar. ALSO verify you are using the SAME type guitar cable for both.OFTEN a TRS cable will NOT turn on the electronics when plugged into a guitar. Use an unbalanced instrument cable unless you have the XLR type output. Use of an adapter from the XLR type cable into the Boss will usually not work.

This is far from normal. What may be the problem is a component on the circuit board itself. You may have to take this to someone who has a multimeter to test and see which one it is (this may take a while, since there are a LOT of small components). If you don't want to (or have the money to) do that, you can just set the balance to the opposite side of the louder speaker until it sounds even out of both channels. Eventually, though, something will have to be fixed.


Hope that helped! Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/cameron_463100ffd54b591d

I wonder why the ribbon cables have been replaced as they do not fail. Check the keys actuate the contacts properly.

I can't! In my opinion, no. Start drift boss customize your car by choosing different colors and patterns.

most likely we dont have crystal balls --need to have diagnosed for problem

Yes, you can use the second pedal on a Roland BK-5 keyboard to transpose the key of the music that you are playing up or down by a semitone at a time. To do this, you will need to press and hold the second pedal while playing the keyboard. You can also use the transpose function in the settings menu of the BK-5 to adjust the key of the music that you are playing by a specific number of semitones.

I am also using IOS and Android. So how can I improve some features? The black screen helps you relax when using the computer too much.

Question edited for a bit more clarity. Video that might help https://www.google.com/search?q=Roland+octapad+spd30+dead Owners Manuals only. https://www.google.com/search?q=roland+octapad+spd30+service+manual ..

It's a Chinese made Roland and no service information is available as when a fault is found the main board is replaced, eliminating the need for service information. I would check that it is a stereo out jack and not mono. If it is a stereo out, check that both input phonos work. If they do, replace the faulty socket or damaged pcboard.
