Cabinet Models - Vox Tonelab LE Owner's Manual

15. TWEED 1X12 (TWD 1X12)
The TWEED 1x12, 18 Watt, all-tube combo is
the very essence of simplicity with a Volume
knob and a single Tone control. This Tone control
is merely a treble cut and boost, and its behav-
iour can be mimicked by using the ToneLab LE's
TREBLE, MIDDLE and BASS EQ network as fol-
lows:
Original Tone control turned all the way
down (off) = BASS on full; TREBLE and MIDDLE
at 9 o'clock (PRESENCE "off").
Original Tone control turned up "full" (on
10) = TREBLE on full; MIDDLE and BASS at 9
o'clock (PRESENCE "off").
NOTE: As the original doesn't have a Presence con-
trol, PRESENCE is "neutral" when "off," but can
be used to add "extra" sparkle and cut to the
style if you so wish.
Original's tube compliment: 1 x 12AY7, 1 x
12AX7 in the preamp, 1 x 5Y3GT rectifier, 2 x
6V6s in the power amp.
16. TWEED 4X10 (TWD 4X10)
TWEED 4x10 is very sensitive and responsive to
both picking strength and the volume setting on
your guitar. This means that by backing-off your
axe's volume when the amp is cranked, you can
produce a beautifully clean and full tone. It also
means that dynamic picking control allows you to
make notes or chords more distorted or clean
than others, depending on how hard or how soft
you pick. Another cool tonal quirk of TWEED
4x10 is the classic, vintage tube amp sag its
GZ34 rectifier tube adds to your notes whenever
the amp is driven really hard.
Original's tube compliment: 1 x 12AY7, 2 x
12AX7s in the preamp, 1x GZ34 rectifier, 2 x
5881s in the power amp.

ABINET AND SPEAKER ACCURACY
There's not much point in having incredibly accu-
rate amp models if the speaker cabinet models
on offer aren't of the same exacting standards. As
you may know, in real life, the output stage of a
tube amp works in close harmony with the vary-
ing impedance curve of the speaker(s) it is driv-
ing. This intimate and vital relationship plays a
major role in producing the warm, punchy sound
and pleasing feel that we all know and love. In a
nutshell, modelling a speaker cabinet is not just a
case of frequency response, but is a combination
of frequency response, transient response (how a
speaker reacts to the strength of how a note is
played), and the all-important interaction of the
amps output to the speaker's impedance curve.
In addition, other vitally important factors that
have to be taken into account when modelling a
cabinet are the actual physical dimensions of the
enclosure (cabinet), the unique tonality of said
enclosure (which will be affected by both the type
and thickness of the wood it is made of) and
whether it boasts an open, semi-open or closed-
back design. Special circuitry and unique model-
ling technology ensures that all of these factors
are well taken care of in the cabinet models built
into your ToneLab LE.
1. TWEED 1X8 (TWD 1X8)
The 8-inch 3.2-ohm Alnico speaker in this cabi-
net is built into a simple, open-backed amp with
a 6V6 output valve.
2. TWEED 1X12 (TWD 1X12)
This speaker is the other half of our Tweed 1x12
Amp. As the name suggests it is a single 12"
speaker, which uses a revered Alnico magnet.
3. TWEED 4X10 (TWD 4X10)
Keeping with Alnico magnet speakers, this cabinet
is open backed and uses four 10" 8 Ohm speakers,
wired in parallel for a total of 2 Ohms impedance.
4. BLACK 2X10 (BLK 2X10)
These speakers are based on an open backed
2x10" ceramic magnet 35 Watt combo.
5. BLACK 2X12 (BLK 2X12)
This speaker system features two 12" Ceramic
magnet speakers. They are 8 Ohm units wired in
parallel for a 4 Ohm total load.
