Txoj haujlwm no muaj cov khoom siv hluav taws xob zoo ib yam rau Ibanez TS-808 TubeScreamer. Ntxiv rau lub rooj tsavxwm no cia koj xaiv ntawm ob peb qhov kev hloov kho ntawm tus qauv qub, thiab siv nws yooj yim. Qhov kev hloov kho tseem ceeb tshaj plaws yog lub peev xwm los tsim txoj kev hla hla tiag tiag lossis tsis hla hla kev. Tsis tas li yuav muaj chav nyob txaus rau cov qauv qub tshaj plaws nyob rau ntawd:

Yooj yim muab "ntau qhov nce"

Yooj yim los hloov Op-Amp

Yooj yim los pauv diodes (suab sib txawv sib txawv)

Yooj yim los pauv ntawm qhov tsw TS5, TS10 thiab TS808

Kauj Ruam 1: Xaiv Los Ntawm Qhov Tseeb Bypass lossis Pseudo True Bypass thiab Solder Jumpers

Los ntawm kev tsim khoom pom, kev hla dhau qhov tseeb tsis yog qhov tsim qauv yooj yim, txij li nws xav tau lub loj thiab kim peb tus ncej, hloov pauv thib ob. Thiab vim tias nws yog qhov ntau thiab qhov nyuaj nws yuav tsum tau muab muag ntawm tes. Kev hla hla hla yog txoj hauv kev ntau lub tuam txhab tsim khoom (Tus Thawj, Ibanez) txo tus nqi tsim khoom. Txawm li cas los xij koj yuav tsum tau siv tshuaj txhuam 30 ntau yam ntxiv kom tsis txhob hla dhau kev ua haujlwm, qhov kev sib tw no yog qhov nthuav ntau hauv cov kab tsim khoom lag luam.

Ntawm lwm cov txiaj ntsig, kev hla dhau qhov tseeb txhais tau tias, thaum koj lub pedal raug kaw, lub teeb liab dhau mus yam tsis tau hloov pauv hla tus pedal, raws li xaim hlua khi ua ke cov tswv yim thiab tso tawm. Koj lub suab yuav zoo meej, txawm li cas los xij txoj kev hla no muaj ob qhov tsis zoo:

Lub suab nrov "nyem" tuaj yeem ua ntawm qhov hloov pauv thiab tom qab ntawd ua kom nrov nrov los ntawm koj lub guitar amp

Yog tias koj siv kab ntev ntev (piv txwv li 6m los ntawm guitar mus rau pedalboard, tom qab ntawd 6m los ntawm pedalboard mus rau amp) koj yuav muaj qhov poob qis vim tias guitar lub siab impedance tso tawm lub teeb liab cuam tshuam ntau los ntawm kab hluav taws xob

Pseudo qhov tseeb hla (tsis hla hla) txhais tau tias, thaum pedal tawm, lub teeb liab hla hla ib lossis ntau qhov tsis. Ib qho tsis yog ib hom amplifier uas tau nce ntawm 1. Tsis yog ua kom nrov nrov lossis ua kom lub suab qis. Buffers tau tsim los kom tsis hloov lub suab, tab sis raws li qhov YouTube Video no, siv ntau dua tsib tus neeg tuav lub pedals, hla dhau tuaj yeem txiav qee cov ntses bass thaj tsam thiab ua kom siab me ntsis. Cov txiaj ntsig los ntawm kev hla tsis dhau yog:

Tsis muaj "nyem" ntsiag to hloov

Tom qab lub pedal tsis muaj teeb meem pes tsawg tus cable ntsuas koj tso, koj tsis muaj qhov poob poob lawm. Pedal cov zis muaj qhov cuam tshuam tsawg, yog li cov peev txheej hluav taws xob txo qis qis dua

TL; DR: siv ntau txoj hauv kev hla lub pedals tsis zoo vim tias koj tuaj yeem xaus nrog lub suab nrov dhau guitar. Kev siv tsuas yog hla kev pedals tsis zoo yog tias koj tuav ntev cable khiav. Muab qee qhov tsis zoo hla kev pedal muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb kev daws teeb meem.

Koj puas muaj lus txiav txim? Tam sim no xaiv koj tus qauv thiab siv cov hlua dhia.

Yog tias koj xaiv los tsim koj li IceScreamer nrog qhov tseeb hla, luv luv "luv rau TruBy" jumper nyob hauv qab "MILK" txuas. Yog tias koj xaiv los tsim koj li IceScreamer nrog pseudo qhov tseeb hla dhau, tsuas yog ob qho "Luv ob rau Pseudo" dhia, nyob hauv nruab nrab ntawm cov tswv yim thiab cov tso tawm.

Kauj Ruam 2: Cia Pib Pib Soldering

Cheebtsam tshwm nyob rau hauv qhov kev txiav txim nws txhais tau tias yuav tsum tau muab pov tseg, los ntawm me me mus rau qhov loj dua. Yog tias koj xav tau kev qhia paub yuav ua li cas txhawm rau txhawm rau txheeb xyuas cov vis dis aus no.
