bbrp buku gitar ada bagi tips utk elak electrical shock masa sentuh tali gtr..terutama kat onstage yg groundnya berlawanan.
utk keselamatan tambahan antara tali & ground, wire 220k ohm resistor dengan .001 capacitor (min 500v) secara parallel antara main ground & bridge ground wire. twist & solder, pastu cam biasa cover ngan tape atau heat-shrink tube.
dgn ni, sebarang possible shock akan dilimit kpd lebih kurang 40v..masih terasa tapi kemungkinan besar tak maut. tapi klau sentuh part2 metal lain cam knob, jack & cable etc still bleh dpt shock la.
aku tak pandai psl letrik ni..so pada pendapat korang, wajib/logik ke tips ni utk kita kat malaysia? bleh ke aku reduce lagi shock dgn pakai knob plastik?

nnt ada time aku nak install la mcm ko ckp ni..
knob plastik tak membenarkan arus bro..

yah tepat dugaanku, plastik penebat kan? tq bro. aku rase mmg patut kite sume install mende ni, just in case..
lupe nak ckp. tips ni ialah drpd gitaris adrian legg dlm buku die customising ur elec gtr. dan erlewine pon ade rekemen ni..so kire ade kredibiliti gak la.

Sebenarnyakan, hahahhaha.
- letak jer fuis before connect to bridge.
- pekara paling bodoh tapi tu la paling logik.
- guna 0.2 Amp nyer fuse la.
- sebabnya pekara letrik ne bukan pasal high voltage jer.
- Current ampier juga ada bahayanya.
- jangan pakai 3A plak.
- nanti current masuk lom sempat fuse bakar, itu guitarist dah OUT.... hahhaahha.
keadah 220k ohm resistor dengan .001 capacitor
- nanti kita dapati grounding string jadi lembap.
- delay sikit baru hilang bunyi noise.
- maksudnya pegang string tak tapi lambat senyap.

eh baru prasan ade post baru. tq ultraman..oo so ade con noise delay gak la kaedah ni. pakai noise gate/supp patut bleh kurangkan prob ni tak? sbb klau faedah lebih drpd con, tak kisah kot noise skit2.
tang method fuse tu..wiki time! hihi

Ko carik kat jalan pasar clip fius kecik, beli fuis 0.1A - 0.2A.
- wiring la wire ground ke fuis before connect to spring claw.
- guitar guitar mahal macam taylor banyak dah guna keadah cam ne.
- tak kisah la high voltage or high ampier ini fius akan putus jika berlaku bebanan.
- dalam keadan normal ia bebanan adalah zero.
Kalo ko pakai cap 440pF dengan 500v, hehehhehe.
- arus still boleh lalu.
- 300-500v pun still boleh lalu.
- resistor 1/4 bpleh tahan sampai 100v.
- 1/2 boleh sampai 200v
- 1 watt 600v pun boleh lalu.
- tapi kalo ini high voltage or arus boleh mai mili mili second pun.
- kita dah kaput... kakkakak.
Pakai noise gate pun tak guna,
- ini delay adalah,
- bila kita tak pegang string, akan keluar noise kat amp.
- tapi bila tekan baru noise tu hilang sebang grounding.
- cuma keadah ne akan menyebab delay skit dari noise ker tak der noise tersebut.

lol kasual je care ko mendescribe situasi tu. oo ok tq2 semakin paham. cume mmg aku kene buat research lebih..byk sgt kene blajo lg ni isk.
tanak la paranoid lebih2 psl shock possibility ni, tp senang cite mmg aku pasni perform pakai active pups je..atau wireless system haha!

salam i-band-ers.. sy bdk baru kat sini..
sy ada sedikit masalah.. kebetulan thread ni exist..
masalahnya begini..
saya ada rasa shock kat gitar saya bila lengan saya tersentuh bridge dan string..
gear yg sy pakai adalah boss gt-10..
shock juga dirasai kat gitar bila pedal tu sy off power dan kadang2 shock dapat dirasa kat body pedal tu jugak ( adapter masih pasang kat extension)
shock hilang apabila saya cabut adapter dr pedal
saya tak tau la ni masalah letrik kat sini atau masalah pedal saya..
saya hrp otai2 bab letrik dpt membantu
thx in advance

- seperti yg anda tahu, adapter GT10 adalah 2 prog/pin.
- mean this gadget need ground dari other system seperti amp or pc anda.
- Jika anda main kat PC, mean pc anda ada grounding system.
- anda boleh guna test pen, test pada casis pc, dan tengok test pen nyala ker tak.
- jika nyala, mean pc nyer grounding dah fail.
- pada PC biasanya disebabkan pleh cable power or socket rosak.
- utk amp, just ON the amp, dont plug ur guitar.
- guna test pen check grounding pada chasis amp anda.
- test pen nyala,mean grounding fail.
- test grounding utk amp direct through wall plug dan test juga bila guna extension.
- kalo plug wall ok, tapi dengan extension fail, mean extensionn wire nyer grounding fail.
Cth
- guitar>GT10>PC or amp.
Cuba test guitar to GT10 saja.
- connect guitar>GT-10 [jangan connect to pc or amp].
- guna test pen, check kat guitar string.
- kalo test pen nyala, mean problem dia dari GT10.
- then sambung Guitar>GT10>amp/pc
- test guna test pen pada string/bridge.
- kalo nyala mean ada problem grounding pada PC or Amp anda.
- Modal, test pen rega 2 hinggit jer.
- kadang kadang Amp or PC nyer grounding ok.
- tapi itu extension power grounding fail.
- So try test dengan other extension juga.
Slamat mencuba.
- post the result here then baru kita boleh suggest aper yg perlu dilakukan.
Test pen
