air conditioned sa room sir, pero yung ibang pedals wla nman syang ganun klase na ingay, only until nung nialagay ko yung wah, nung sinubukan ko nung na wala nman, bali hiwalay pa nung tinest ko, then nung nialagay ko na sya sa mismong board ko, ok pdn nman, wla pdn nman tunog pero nung inadjust ko sya to test
biglang nagkaroon, some forum says bka dahil malapit yung wah sa power supply or bka sa cable, pero yun nga po tinry ko nman na ihiwalay yung wah e meron pdn, so yun.. hehe
1)
"malapit yung wah sa power supply" → it could be.. kasi ang point of discussion here is yun interaction between 2 magnetic fields..
magnetic field ng transformer ng psu at yun
fasel inductor ng wah (that is kung meron siya)..
now being both coil, puwedeng manghawa sila ng magnetic field and/or other interferences (e.g. RFI - radio frequency interference) at puwedeng mahawaan ng magnetic field and/or other interferences.. kaya critical sila..
but there is an exception → i believe both psu and wah pedal are
well-enclosed. so considering this,
redundant na yun issue about the magnetic fields interactions.. sa akin lang when i suggest sa mga clients ko na ilayo sa psu yun wah.. it's just being too careful..
2)
"airconditioned room" → there's no point of argument naman with this.. most especially if we love our gears that much.. but be very wary.. mag lagay ng
silicone beads or any other mositure absorbent.. because every
metal naman are
permeable with vapors.. mapa gold man siya or just plain iron.. even glass and plastics are all permeable with vapors..
now, kapag sumipsip na ng cold air yun metal parts most especially yun
metal part ng connectors.. may mga kasamang heavy metals or micro dirt yang vapors..
kapag nabago ang temperature ipapawis at matutuyo madalas kasama ng dust or micro dirt na kasama ng vapors.. pero none the less, kahit may bag man ang mga pedals or hardcase.. once the vapors reaches the metal part ng connectors.. eventually it will build atleast from a start a
thin layer of dirt.. minsan nakukuha alisin sa pag-ikot-ikot ng plug ng patch cable or tanggal kabit.. worse kapag makapal na yun layer magkakaron na ng
discoloration.. next thing we know kinain na ng corrosion yun
tin-coating (titanium nitrate) ng brass hardwares kaya madalas kapag naalis yun corrosion mawawala na yun tin-coating at tanso (brass) na yun lilitaw.. mas prone na ito sa copper corrosion or
patina..
therefore:. as i told my clients everytime.. if you love your gears, clean them atleast once a week.. with alcohol-based not oil-based or with out silicone residue cleaners..
though i have an experience before.. may nagpapalit ng knob ng isang clyde mccoy wah.. he told me it was scratchy pero turns out after palitan ko ng ilang beses ng bagong potentiometer yun acclaimed scratchy pot eh hndi naaalis yun noise.. turns out may
electrostatic noise or some sort of
stray voltages or
earth potential rise going on inside it's circuit kasi mukhang something like electrostatic noise is eminating from the circuit which causes this potentiometer to trigger ESD (electrostatic discharge) everytime it's being rotated..
my point is baka may ganun yun wah pedal.. this is all academic lang naman incase cleaning does not answer our problem, we have other things to consider..
