    Mine just started doing the same thing. The only way I can even get the mode to inst/ mic is to power on with the exit or write button pressed, then nothing happens and as soon as I release either button all 3 of my indicators come on and it's frozen. Did you find a solution by any chance?

Most PROBABLE is the output jack either has been broken (common due to mishandling and accidents with cables such as stepping on the plug while plugged into the pedal) or the soldering of the jack in the pedal has broken loose. Less common is a circuit board crack in the vicinity of the jack. Open pedal and inspect for the above suggestions.

Hi. I had the same problem and fixed it by clearing all the phrases. An explanation of how to do this is below (written by someone else, not me) But, expect your guide beat to now sound like a fuzz instead of a drum. This really sucks and there is apparantly no fix for the guide sound except to send it back to Boss. Good luck.

1. Start by selecting Phrase 1.

(if the 'REVERSE' or 'AUTO START' are lit press them off.)

2. Select 'INST & MIC' by pressing 'MODE'

3. Hold down 'EXIT' and 'AUTO START' together - at the same time, this should light up the green LED for 'LOOP PHASE'

4. Hold down 'WRITE' and 'EXIT' together
then hold 'WRITE' on its own
then 'WRITE' and 'EXIT' together again...as if you were clearing a phrase.

they should light up in red and flash, if not try a combo of section 4.

5. Repeat on all Phrases 1 - 11.

Weak batteries or power adapter would cause this.

It is strange that it comes on when you plug into the OUTPUT... It should come on when you plug into the INPUT... could you have the jacks/plugs backwards? If cables are backwards, the bypass function will still pass your guitar backwards through the controls. You would NOT be the first person to mistake the labelling of input and output. There may be another problem of course, but do check the in's and out's. The fading out of the LED's is NORMAL when power is removed due to storage of the power by capacitors internally that bleed off.

If it does not power up, it is likely going to be a faulty or severly dirty switch contact or a failed capacitor in the power supply. A shot of contact cleaner is usually enough to rectify the first issue, The second issue you need to locate the part at fault and replace it.

I would suggest cleaning the input jack, and if that doesn't fix it, replacing the jack.

I have the Roland Boss Rc-20xl Loop Station, and I'm running off of batteries I have been since I got the pedal. In the middle of recording a phrase the pedal shut off and started resetting itself...


Hello!
I am not positive on this but I would try to clear all of the loops. Try holding the right pedal for about 5 seconds.
If that does not work, hold the right pedal for about seconds while you turn off the unit. Release the right pedal then turn the unit back on.
Hope that helps!

I was trying to transfer data from the RC-50 to my computer and pulled out the USB cable by mistake from the computer and now the RC-50 says Data Damaged. I think I may have put the file in the trash in...


Usually in any type of situation when data is being transferred and the connection is prematurely lost there is data lost and or file corruption.



My suggestion:

Connect the Boss Rc 50 to your computer and backup its entire contents to your computer if possible.

Next perform a Hard Reset: While simultaneously holding down the "PLAY MODE" and "LOOP SYNC" buttons, turn the power on. Everything should be restored to factory settings.



If your backup was successful, then you can transfer desired files (one at time) to determine if the are usable. If a file causes errors or malfunction, then most likely it is corrupt.



Hope this helps

My boss DD-3 makes a strange tapping sound on all modes. tapping sound gets more frequent when i turn the delay time pot to the right. its like a little tap sound getting into the circuit with the guitar...


Check your power source or battery. The sound is probably due to the internal processor recycling due to watchdog timer. If power is OK, then service will be necessary to repair the problem.

My Boss RC-50 has stopped working. I used the power chord for my RC 50 in my Boss OC 3 pedal and then tried using the chord in my RC 50 again and it won't work. It won't even work with other power...


CHeck the voltage out of the adapter. It should be around 9 to 11 volts. If it is not, it is possible that the OC3 has reversed polarity AND a protector that put a short on an incorrect supply. If so, it could have damaged the RC50 adapter. If the RC50 adapter is putting out correct voltage, then I suspect the inout connector on the RC50 may be damaged or not quite seated. Visually inspect the connector first.

Beggining of loop missing on FIRST playback only, on Boss RC-50.


Ok, solved this problem by visiting roland U.S. site as the help offered in this country is useless. The instructions given by email would not have worked even after the update was installed. Luckily, there are instructions that come with the download. If you have same problem as me go to http://www.rolandus.com/products/productdetails.php?ProductId=772&tab=downloads&skip=true

and update the opperating system on the RC-50 to RC-50 System Update Version 1.01.

Then hold loop sync and phrase 2 button (think it was phrase 2) to change it to sound priority mode. Then it will play back correctly what you recorded on the first loop, rather than missing the first beat.

Am v.happy I have found this, as after much searching I can't find any other loopers out there that offer 3 seperate loop tracks and the ability to switch between them effectively. Plus, it's a very convenient size, better than a load of rackmounted stuff to haul around.

However.....

Another problem..

When hitting the reverse switch ( I assigned both external footswitch and the onboard Tempo pedal to reverse) the change is not instanteaneous. There is a second or so delay before it plays in reverse. Not a problem for most, I suppose, but I have a piece that switches rythmicaly between playing forward and reverse which means hitting a pedal in time and reverse/forwards changing immediately. I think they could do with another software update to solve this. Now I have to keep room in my enormous pedal board for the old rc-20, as that does the reverse as it should - when you hit the flippin switch!

How To Turn Drum Beat Off


From what I remember from my recent tinkering you press the guide select button. Then either use the patch/value know and parameter buttons, OR it may be the guide level knob to switch the volume down until it is off. I believe I then saved the patch to preserve the setting and keep that irritating guide at bay! It really should be more intuitive, ideally knod turned to zero = OFF. But no. Ah well, hope you get it sorted. I have a problem too, maybe you have same one? It may be the unit itself. Search - Beggining of loop missing on FIRST playback - if you get a chance. Let me know if yours does it too?
