My LS-2 has gone microphonic when you touch any of the outside casing and making a slight crackle.... some of the regulars will have read my tale of woe a while back when a rather large PA speaker was pushed over onto my pedalboard at a gig with the LS-2 taking the majority of the damage.....i fixed it(thanks to laurie) but this has started happening recently........drunken punters.......i bet this shit never happens to clapton..........
Please disassemble her: Look for hairline cracks in the circuit boards. (bright daylight or halogen desk lamp, behind the PCB is best for this).
Take a lot of pics & let us all see if we can spot anything.
The switch or pot may have gone south.
Also we (Laurie & I), have been finding a lot of cracked & broken Input-Output sockets. Insert a plug into them, gently jiggle it around a bit to see if it's cracked mechanically.
Cheers Dr Bob......will do and report back soon..the 'board is in the van so it will probably be wednesday or thursday before i get a chance to do it....
