Boss RC20 loop station

[DrGonz78]

So, I have this RC20 loop station that I have fixed... Well it was really just the means of resetting the phrase memory banks 1-11. It was all malfunctioning when I got the unit and did not work at all. I was reading on another site where the guy had cracked this combination of codes to reset the unit and it worked. The only problem with the pedal now is the tempo guide effect is like that of buzz sound rather than a thud. It sound really bad but still in time and functioning enough to use it to keep time. The guy on the website that fixed his w/ the codes to reset the memory banks still had the same problem.

I am using the correct plug in adapter for this pedal: 9.6v : 200ma wall wart.

So, does anyone here have any clue at all if there is a fix or something that can be done to figure out how to get the tempo guide sounds to be normal again. Probably a long shot here but really just trying to fix this thing to see if it can be done.

Anyone that has come across this defect in this product is encouraged to give some information about their experience. This might not be easily fixable, but seems a bit common in some regards to searches I made online.

There are 4 types of guide tone. Are they all sounding like a "buzz"?
In case you haven't tried them all, : Q.How can I change the guide tone on the RC-20XL/RC-20?

A.While holding down [EXIT], repeatedly press [TAP TEMPO] to step through the available guide tones (eight types on the RC-20XL, four types on the RC-20).

Hey thanks G-one but I had failed to mention that I had tried that procedure already. It just stays on the same noisy buzz metronome. First buzz is quiet to mark first beat, so it actually still functions in that regard.

Just wanted to see if some other people who had the exact same problem online might be on this site to see if they ever figured out a fix. Probably a major failure of something component wise that set all the memory into a state of malfunctioning. Once you reset the each individual memory location 1-11 then you have a functioning loop station minus the guide tone is acting funny now.
