Introduction
Thank you for purchasing the VOX AV30/AV60 analog valve ampli-
fier. To help you get the most out of your new instrument, please read
this manual carefully.

Main Features

- Our constant R&D of analog designs has enabled us to create a
whole new category of analog modeling guitar amplifiers. This
research allows us to create the sound of legendary tube guitar
amplifiers.
- The Pre-amp is powered by a 12AX7 (ECC83) tube. This delivers a
more dynamic and harmonically rich sound. For greater flex-
ibility, you can change some tube parameters to really customize
your tone. AV30 and AV60 have 2 independent channels.
- The Power-amp also includes a 12AX7 (ECC83) tube, allowing for
real tube power amp distortion, even at lower wattage levels. Like
the pre-amp, you can also change tube parameters in the power-
amp, for greater flexibility.
- There are 3 types of analog voiced digital effects included. Each
one can be used independently. Pre-amp channels and the EF-
FECT section can be controlled by an optional foot switch (VFS2,
VFS5).
- The AV30 and AV60 also have an Effects Loop, and an External
Speaker Output.
- The AUX IN allows you to plug in your own portable music
player, so you to jam along with your favourite tracks. Plug your
headphones into the PHONES jack, for silent practice. This output
is powered by an analog cabinet simulator, giving the real feel of
a guitar amplifier.
