Make sure the power supply for this is powered from the SAME receptacle as your amplifier is powered. Keep the cable from this to the amp fairly short and high quality cable. Keep guitar away from magnetic field sources... the wall wart adapters are notorious for generating magnetic fields.

The obvious answer is to have it repaired. Sometimes the parts can be hard to find but either DigiKey.com would have the part or you can go to Roland/Boss and order the part. If the knob itself was smashed, the pot also is likely damaged. $5 of parts should fix it up. If you are adept at electronic repair it should be an easy fix.

Sometimes, with BOSS pedals, the battery must be disconnected before using another power source. I ran into the same problem with my DS-1 distortion. If it's not that, then check the power rating of the power adapter. It should read, for the output, exactly 9V DC. If it doesn't, then you have to get a power adapter that has that same rating. Boss pedals will not use anything other than 9V DC (I know, I've tried).

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.

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.
