assalamualaikum para2 gitarist sekalian
aku ada gitar LTD m-50 indon made
gitar tu memang byk berjasa la dengan aku
hingga aku tak mampu nak tinggalkan beliau
tapi sekarang gitar nih dah ada masalah la plak,
aku nak tanya la pada pakar2 sekalian

aku rasa knob kat volume aku ada masalah la,rasanya la..
bila aku pulas kan dia habis ke "kosong" bunyi dia takde perbezaan langsung
yg ada ubah sket pun ialah volume dia "kurang "sikit je
dulu mmber aku ada la gak betulkan wiring dalam tuh,tapi bila aku
try men plak,aku test volume dia,memang takde perubahan bila aku pulas ke
"kosong", aku rasa mmber aku tuh tak buat dengan betul kot,


jadi ape ek masalah sebenarnya LTD aku nih??


aku ingat nak cuba buat sendiri wiring ni sume,korg ble bagi info atau
cara2 yang selamat tak pada aku nih,

Simple jer tu, connection to ground = failed.
- just pastikan conection to ground pada pin 3.
- biasanya dioang solder pin 3 ker belakang pot, dan belakang pot plak connect to ground jack socket.
- Atau, pin 1 dah bersdentuhan dengan pin 2 kat volume pot. so tak der la effect volume.

aku tgk yg bergabung ialah wire yg utk jack in tu dah digabungkan dgn wire daripada tone
jadi benda tu kira fail la kan??kira takde effect ape2,cam turun kan volume takde perubahan,

ni kalau ikutkan aku la kan
untuk volume pnya pot tuh,
wire untuk jack in,solder kan ke 3 pin volume tu kan??
and 1 white wire daripada tone,solder kan ke volume punya pin,and 1 white wire drp pick up selector solder kan ke volume punya pin,kira nanti ketiga2 pin tu dah disolder kan kira,
baru ada perubahan ke??


maaf saya budak baru belajar,ingin mencuba sesuatu

x fail. mmg wiring die mcm tu.
wire dr tone pot -> jack = ground.
wire dr vol pot -> jack = hot wire.

wire pikap m-50 ade kaler putih and hitam.
putih = hot
hitam = ground.
and wiring switch kt m-50 pelik sket, aku pon x ingat sgt.
tp aku rase mmbr ko x usik sgt la kt situ ko sblum ni, harap2.

ang tgk diagram bwah tu.
just concentrate kt wiring pots saja.

ok ni gambar wiring kat M-50 aku,bak kata bro cosmo ada wiring yg dah bercantum,
berdasarkan pada mata aku,apa yg aku nampak ialah
wire utk jack dah bergabung dengan wire tone dan wire utk switch
correct me if im wrong

wire dr tone pot -> jack = ground.
wire dr vol pot -> jack = hot wire.


aduh! lembab nya aku. Confused
termiss la plak.
aku rase salah tu.
wire 'output' ngn wire "vol pot -> tone pot" xde gabung.



yg ko label sbg switch, tone,input tu aku x nampak clearly 'mane solder ke kaki mane'.

sbg rujukan, aku tanda ngn panah kuning:
kaki no.1- hot/signal (solder to tone pot)
kaki no.2- output (solder to output jack)
kaki no.3- ground (solder blkg vol pot)


tp yg aku nampak x kena kt gamba tu ialah:
(dlm kotak merah)

1- kena ground kt belakang pot. itu yg bro utromen ckp 'ground fail'
2- nampak mcm tercabut. atau wire dah bercabang, tp sparuh je yg solder.
3- penabat die nampak mcm terbakar terkena solder.
kalo wire dlm tu exposed, then selit2 ngn wire lain nak sloder kt kaki yg sama,
wire yg exposed tu mungkin kena wire lain. 'fail' la alamatnya.

so try betulkan prob no.1 & 2 dulu. tp sblum buat,
tggu bro utromen post die punye pendapat dulu. i might be wrong.

anyhow, aku dah email esp mintak wiring diagram.
dlm website, its stated 2-5 working days for a respond.
so kalo dapat wiring diagram cun la.

Sebenarnya, aku pun sependapat dengan cartman. Tol la tu. Weldone my friend.

Tapi aku syorkan, desolder balik the volume part, ia bukan roket science pun. Kata orang kalo main guitar kena belajar tuning, pastu intonation, pastu wiring dalam tu utk guitar letrik. hahahah.

1. Desolder balik volume pot, tone pot biar jer dulu.
- release semua connection.
- desolder ground balakang pot, do it fast jangan sampai over heat terutamanya solder balakang pot.
- over heat pot akan mula bunyi krack krack masa turn pulas knob.
- panaskan kaki pot tu pun jangan over heat.
- jangan lupa pusing lawan jam pot tu sampai habis [position volume zero]. Sebab kalo over heat ia berlaku pada zero volume so kita tak dengar krack pada erea ne. tapi kalo half of the tone pot, kita kan dengar krack masa turn knob pada that area yg burn.

2. check itu pot
- pakai multimeter, check balik pot volume tu fungsi ker tak,
- pusing abis lawan jam, ukur pin 2-3 and pusing knob pelahan lahan arah jam and tengok meter supaya kita nampak resistance naik.

3. solder balik ikut diagram betul.
pin 1 hot from switch
pin 2 output to jack
pin 3 to ground pelakang pot.
- ignore tone pot dulu.

4. kasih test bunyi ker tak.
- tak payah connect to tone pot, dan try check guitar tu bunyi ker tak.
- bila volume dah fungsi dengan baik baru connect tone pot ke volume.
- kalo ada masalah berlaku mean tone pot area ada masalah.

Sebenarnya aku tak nampak sangat gambo tu, melainkan ko lukis sendiri diagram tu atas n tag wire berkaitan. Some wire aku tak tau pun datang dari mana terutama the black one. Sebenarnya aku pun selalu dapat masalah masa wiring guitar dulu, bila redo balik tetiba ok plak. Aku sendiri pun tak pasti mana satu yg aku tersilap sebelomnya. maybe sebab wire sentiasa berserabut dalam cavity tu...
