počel mi je krčati i prekidati volume potenciometar. kad ga vrtim otprilike negdje na 3/4 prekine i uopće nema zvuka sve dok ga ne okrenem do kraja pa se onda pojavi, a i inače šumi i krči. tak da bi ga onda zamjenio, samo ne znam koji potenciometar trebam. 250k, 500k,...nešto treće? gitara je Jackson PC3, pikapi su Seymour duncan JB i 2x STK-S1 dakle HSS konfiguracija.

Možda preskače negdje.. Ja bi tu malo WD40 zaposlio


kurtcobain994: Dakle svirao sam gitaru i pukne mi prva zica (najtanja)...sad da neidem u grad jer mi je daleko moguli ja staviti onu zicu od sajle ili nesto slicno da bi mi zvucalo isto kao prva zica..... nadam se da me razumijete

znam da je WD40 univerzalna stvar za popravljati apsolutno sve :), ali ne bih baš špricao oko drva tak da bih ga ipak zamijenio, a nije ni neki trošak

Pametno... Sačekaj ove pametne možda imaju neki dobar savjet

Nisam stručnjak, al zato gugle puno zna:

Prvi korisni dio:
Citat
There's an effect on the brightness. Primarily because everything the pickup 'sees'; the values of the pots, tone capacitors, the capacitance of the guitar's wiring and also the guitar
cable, all affect the highs slightly, in a way that's more noticeable to the player than to a listener. Because it mostly affects the initial attack transients, right as we pick the string, the difference is less noticeable after a note has rung for a bit.

...

1. LARGER value pots will shift the tone to a slightly brighter range, and may increase noise slightly. This is the reason many Fender guitars use the lower 250K value, to provide a slightly warmer tone and lower noise from their bright single-coil pickups.


Drugi:
Citat
general "rule-of-thumbs":

1Meg = very bright sounding
500K = bright sounding
250K = warm, vintage sounding

1Meg = bright HB...shrill SC
500K = warm HB...bright SC
250K = muddy HB, warm SC

HB = humbucker
SC = single coil

...the HIGHER the pot resistance value, the LESS high-frequencies are attenuated.
...the LOWER the pot resistance value, the MORE high-frequencies are attenduated.

TONE control pot value doesn't matter too much because the overall "taper" or "rolloff" can be 'adjusted' by simply changing the cap value.


Treci:
Citat

The pot value (usually 250K or 500K ohms) affects the brightness at 10 (higher = brighter) and also the proportion of treble loss as you turn down (higher = more loss).

The pot quality does also make a noticeable difference - physically bigger pots (US-made CTS, or similar) have a bigger, more open and brighter tone than smaller ones (eg typical Far-East made mini-pots). This is due to the 'parasitic' capacitance of the parts and materials in the pot.


Cetvrti:
Citat
Some pots will have the information stamped into the casing but if you are unsure you may wish to check the manufactures site for a wiring diagram or schematic for more info. You can experiment with different value pots but most commonly you will find 250K pots used with single coil pickups and 500k pots used with humbuckers.

edit: Na tvom mjestu, kupio bi jednog od 250k, jednog od 500 i sprobo koji mi bolje pase. Kad vec lemis.
