Ausstattung/Klang:
Die werksseitig verbauten China Röhren (2 x 12 AX7, 1 x EL 84) sind nicht einmal die Schlechtesten. Ein kurzer Wechsel zu JJ`s brachte nur marginale Veränderungen im Klang zu Tage; will heißen: etwas smoother vielleicht, aber immer auch Geschmackssache. Der Speaker ist der gleiche wie beim AC 4 TV und klingt nach einer gewissen Einspielzeit richtig ordentlich. Ich habe beim AC 4 TV später einen Weber Alnico eingebaut. Sicher, der löst noch etwas detailreicher auf und komprimiert auch schön. Dennoch sind das keine Quantensprünge und man sollte dem "Stock-Speaker" durchaus eine Chance geben. Die Aussage "special-voiced by Celestion" trifft voll zu. Er bringt die typisch vox-eigenen. leicht höhenlastigen Töne sehr gut zur Geltung. Apropos Höhenlastigkeit: Top-Boost ist höhenlastig! Wer`s nicht glaubt soll sich bspw. mal einen AC 30/6 TB ansehen. Dort wird er einen Cut-Regler vorfinden mit dem gerade diese manchmal etwas schrill wirkenden Höhen bedämpfen kann. Selbst ein End-90er AC 15 TBX -den ich besitze- hat diese Höhen..
Das ist absolut kein Nachteil, denn man kann ein Zuviel an Treble sehr gut mit dem entsprechenden Poti an der Gitarre abdämpfen. Allemal besser als beim V5 von Bugera, der eher wenig höhenreich ausgelegt ist.
Die Klangregler (Bass - Treble) sind durchaus effektiv, beinflussen sich aber gegenseitig. Angeblich beruht dies auf einen von Gibson übernommenen "Erdungsfehler" des Bassreglers in den 50er Jahren. Mittlerweile ist dies aber typisch Vox.
Man darf aber nicht unbedingt einen voluminösen Bass erwarten. Hier setzt das kleine Gehäuse und wohl auch das Gesamtkonzept der Schaltung dem Bassfundament deutliche Grenzen. Zum Vergleich: der AC 4TV hat da ein wenig mehr "Bottom". Allerdings ist dessen Gehäuse auch eine Spur kräftiger.
Clean ist nicht sehr viel drin - auch hier kann man aber durch Interaktion des Gain- mit dem Volumeregler ganz vernünftige Zimmerlautstärkegerechte Settings hinbekommen. Angezerrte Sounds sind allererste Sahne! Dafür ist der Kleine ausgelegt, das beherrscht er! Man hört unweigerlich den typischen VOX Top-Boost Sound heraus der so markant und einzigartig ist. Sehr gut gemacht.!
Zu guter Letzt die Frage: lohnt sich der Umstieg vom AC 4 TV auf den 4 Blue?
Die Frage muss sich jeder selbst beantworten. Der AC 4 TV klingt sehr ähnlich und vor allem gut. Der neue Blue ist -für mich- eindeutig hübscher und durch die aktive Klangregelung ein klein wenig flexibler. Der Blue bleibt und der andere kommt in die Bucht........

Persönlicher Tip: ich habe nach vielem Probieren mich für folgende Röhrenkombination entschieden: V1: JJ ECC 81, V2:JJ ECC 83, V3: Mullard EL 84, Speaker: Weber Alnico Blue Pub. Diese Komponenten waren vorhanden und klingen einfach nur gut! Durch die 12 AT 7 als V1 ist der cleane Regelbereich ein wenig größer und der Amp klingt eine ganz kleine Nuance weicher.

Here are my impressions:

Processing:
excellent, as one notices a high standard, also with the Vox China models.
Also the circuit board is clean and clearly structured, really nothing to complain about.
In addition, the little one is always attracted by the blue tolex with the greyish front covering; a true eyecatcher.
