Greetings! Happy new year!
 
	 
 
	My sweet Hd500x has several problems:
 
	 
	The 4th rotator (under the LCD screen),
 
	the tap, up and down and and the fs5 footswitches  are almost dead.
 
	 
 
	I live in Greece and Line6 lists only a shop 600km far.. 
 
	 
 
	
		1. Any good diy guides to repair.. or 
		2. e-shop in Europe to find Heavy duty replacement buttons and knobs or maybe the footswitch pcb
	 
	
		3. Should I try using compressed air or liquid cleaner, above or below the surface?  
		3. any other suggestions would be welcome
