For us guitarist,some noises originating from our gear are accepted because of its design and nature but not to a recording engineer,its the opposite.Any unexpected noise emit by their gear would put a dent to his mood/creativity/work/hobby/effort.What more when its an intermittent during it.Not only the session going to be unpleasant,the engineer too might add high dB of foul noise amplified through his vocal chord.Hehe.
Having said.I was ask by a client to look into his Motu 828mk2.What do I know about recording tools? Nothing! What do I know about interfaces? Nothing! It does have similar technology to amps but in that side of the recording realm.Silence before action is the first amendment.
I dismantled both pots,give them a good clean up/bath,crimp it back,test it at his realm and noise gone.For how long? I don't know,no guarantee.Maybe it'll last for several days?several months?several years? Will I be expecting future visits of this unit.Definitely but will be denied.If you've ever tried desoldering out any component in a tight spot,on a dual sided pcb with tiny traces going around,you'll know why.
