preamp tu sebenarnye bukan literally Ampliflier.
sebab dia tak amplify kan sound tu
dia hanya 'color' kan
electric guitar on its own adalah instrument yang tidak lengkap
kalau kita cucuk guitar terus masuk line-in kat sound system
bunyik dia lembik
itulah bunyik electric guitar yang sebenar
electric guitar memerlukan preamp untuk 'color' kan sound dia
so apa bila org ckp 'clean', sebenarnye bukan lah cleam yang literally
sebab mmg telah di 'color' kan oleh preamp
cumanya ia di panggil 'clean' sbb tiada atau tak banyak distortion berlaku
so kalau Guitar kita melalui preamp dan kemudian baru di masukkan ke line-in
ianya telah di 'color' kan
hasilnya kita akan mendapat bunyik guitar yang biasa kita dengar
cuma.. bunyi guitar ini tidak kuat
so untuk menguatkannya.. kita perlukan power amp
Amplifier yang literally adalah power amp
power amp amplify kan signal tersebut
ia menambah power kepada signal tadi
power amp secara mudah nye boleh la dianggap fungsinya hanyalah untuk kuat kan signal tadi
Guitar - Preamp - Power Amp
bunyi yang telah di 'color' kan tadi akan di kuat kan oleh power amp
tetapi yang membeza kan power amp guitar dan power amp lain seperti hi-fi
ialah distortion adalah susatu yang tidak diingini di power amp hi-fi
manakala kalau distortion di (tube) power amp adalah sesuatu yang disukai untuk guitar
ini kerana power amp distortion boleh dikatakan me 'warm' kan signal tadi
tetapi kalau dah guna power amp jgn lah kita cucuk masuk line-in sound system kerana itu adalah kerja gila.. hehe
apabila org menyebut Guitar Amplifier
kebiasaannya ia adalah package yang mempunyai preamp dan power amp
so Guitar Amplifier adalah (Preamp - Power Amp)
so kalau kita gunakan preamp sebelum guitar amplifier
sekarang ini chain kita jadi macam ni
Guitar - Preamp - Preamp - Power Amp
so kita dah color kan signal tu 2 kali.. mungkin akan menghilang kan clarity dan definition
adakah itu perkara yang bagus?.. saya pun tidak tahu... boleh di experiment
EL84 tu tube power amp
so Marshall EL84 tu adalah power amp
20/20 tu secara kebiasannya bermaksud dia ada 2 channel 20 watts
dan oleh kerana power amp ni keje di untuk kuatkan signal je..
mmg knob dia sikit
kalau tak dia dah lari dari matlamat asal |

Guitar > Preamp [external preamp] > (return loop)Power Amp
So tak color 2x.

U have to realized, power amp pon ade tone dia jugak. Sbb tu byk tube power amp dtg with different tubes configuration

Depends...
Power amp distortion is not easy to achieve. 1st off it has to be very loud, & then ade jugak disadvantage dia. In a rackmounted rig, kalo power amp tu dah clipping, it pretty much will only give u 1 type of sound, which beats the purpose of using it, lg senang kalo pakai simple tube amp je. I've seen in many guitar rigs where ppl uses 2 power amps; one for power amp distortion sound, the other for other sounds/tone.
Basically any tube pwr amp will sound 'warmer' compare to ss pwr amp, but pwr amp distortion can also occur in ss amp, & most of the time the sound is not so musical. Tp ade jugak ss pwr amp yg emulate tube pwr amp, like Tubeworks MosValve, tp retail price dia mahal la...
rgx2n...
Rocktron stuff blh dpt from Mahogany, dorang still carry brand tu. Kalo nak order pon blh. Phitone office dia kat D'sara Heights...
Dual recto rackmount tu mmg recording preamp, specifically design for recording. U kan just hook it to a mixer & u're set. Ade jugak org pakai live, but they say it sound better at the PA than through speaker cab. retail dia last i checked was arnd USD1.2k kalo x silap...
Cheers...  |

iye Encik Dufresne.. hehe
saya hanya menyampaikan apa yang saya paham
tetapi hendak lah diingat ya kawan-kawan
Encik Dufresne lebih berpengalaman dan memahami, so words dia lebih bagus dari saya ya!!
power amp ade tone sendiri.. saya sedar
maksud saya basically itulah function nya
saya juga sedar tube/configuration berlainan membawa kepada tone berbeza
saya juga sedar power amp distortion is not easy to achieve
sbb ia memerlukan signal yang kuat untuk men distort kan tube
sbb tu ada org tak suka master volume dan guna attenuator
tapi nanti speaker lak tak cranked
mungkin boleh guna speaker isolation cabinet
tapi sound nye pulak cam 'tertutup'
senang cite dapatkanlah studio sendiri.. tentu lebih best!! |

X de la, its not like that at all. Mcm biase, suma gear yg org pakai, ade advantage/disadvantage dia...
Rack f/x, walaupun sound dia sedap, sometimes is hard to get the sounds that u like. Kadang2 nak setting pon susah, lps tu nak save sound lg, bende2 tu leceh, byk org x suka. Stomp box problem dia if u like a few different sound from one stomp box, kena beli la beli 2-3 bijik stomp box same, semata2 nak main. Lg 1 problem dgn stomp box is that if u use a lot of 'em, it tends to get very noisy...
Byk org preceive rack gear as being the ultimate high end product yg company tu blh buat. E.g, Korg DTR-2 rack tuner. Mmg high end tuner, the best from Korg. Utk org yg ade duit, & wants the best stuff, this is it. Same jugak mcm Crybaby DSR-2SR rack wah, bg aku this is the ultimate wah la, suma sound wah ade...siap blh taruk 3-4 wah pedal on stage lg tu, which is cool...if u're on a world tour la...
Lagi satu its about the sound, setiap product ade sound dia sendri, yg bende lain x de. Kirk Hammett's live rig, mmg besar giler, tp for preset solo, dia still pakai Ibanez TS-9, which is actually 1/2 of his solo tone.
Same gak dgn John Pettruci, walaupun rig dia besar kaw2, & dia pakai some of the best f/x ever, dlm signal dia still ade a few Boss & MXR pedals. The Edge of U2...dia pakai 2-3 bijik Tc Electronic 2290, one of the best delay f/x ever, tp still ade a few EH Memory Man dlm rack dia...its just a matter of what sound that they like, & how to get it into their rig, tu je...
