Laulava Kylätohtori: lieneekö Voxit muuten kovinkin kirkkaita pelejä?
 
Sanotaan näin: ainakin AC30:stä saa kirkkaimmillaan kirkkaampaa ja heleämpää soundia kuin muista omistamistani vahvistimista. Siitä huolimatta niistä saa myös aivan "tavallista" ja jopa tummaa soundia riippuen säätimien asennosta. Lähinnä sanoisin, että säätövaraa kirkkaassa päässä on enemmän, kirkkautta on siis "hanassa" eri tavalla kuin muissa koneissa.
 
Netistä löytyi haulla ainakin tämmöistä, kiinnostavaa infoa:
 
"Vintage AC30s come in different flavors, and many people just aren't aware of this. The very first, the AC30/4 is the original AC30 which started the craze. This is the AC30 which uses the EF86 pentode. This amp is very gainy, and gave the Shadows their famous sound. Only the very earliest AC30s have this circuit, have black control panels, and have only 4 inputs (2-channels). IMO, these are the best sounding AC30s, period.
 
As for the familiar red panel AC30s that followed, they came in three models, "Bass", "Normal", and "Treble". You can determine which a particular amp is by looking for a single letter (B, N, or T) stamped next to "AC30" or the serial number on the serial plate. Also, if you remove the back panel of the amp, you'll usually see the word Bass, Normal, or Treble written in orange, on the chassis, right under the power switch. These amps all sound like ac30s, but sound different as per their designations. The Bass models are bassy, the Normal models are more 'natural' sounding, and the Treble models are trebly.
 
Also, the three different brands of transformers used in these amps tend to give different twists to the sound as well. Since these amps use 12AX7s and have three channels, some gain was sacrificed, and when the complaints came, the add-on top boost circuit was invented. Sometime in what seems like late '64, the top boost became standard, and these amps have both a Bass and Treble knob on the control panel, as opposed to just a "Tone" control. There are separate schematics for each model AC30 which clearly show the minor differences which differentiate each model."
 
Itseltä löytyy Bass- ja Treble-mallin AC30:t, vieläpä juuri tuon "top boost -aidan" molemmin puolin. Molemmissa on Albion-muuntajat. Bass-kone on ajalta ennen top boost:ia, Treble-koneessa top boost -kytkentä (eli enemmän vahvistusta sekä bass- ja treble-säätimet) löytyy vakiona (ei jälkiasennuksena). Molemmissa koneissa on oma soundinsa, mutta molemmat soundaavat hienolta ja molemmista saa kyllä sen "klassisen" AC30-helinän - jos vaan uskaltaa vääntää isolle. ;)
