TONAL HINT: BLACK 2x12 is the perfect partner for ACOUSTIC (Acoustic Guitar
Simulator) in the Pedal section.
15. TWEED 1X12 (TWD 1X12)
The original we modelled here was born in Fullerton, California, in 1958, and clad in
“tweed” - hence its name! Just like the AC15, this 18 Watt, 1x12, all-tube combo is
the very essence of simplicity. Aside from the obligatory Volume knob, it only housed
one other knob - a single Tone control creatively named (wait for it!) Tone! This Tone
control is merely a treble cut and boost, and its behaviour can be mimicked by using
the Valvetronix’s TREBLE, MIDDLE and BASS EQ network as follows:
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 control, PRESENCE is “neutral”
when “off,” but can be used to add “extra” sparkle and cut to the model if you so wish.
In keeping with the original, the TWEED 1x12 produces an open, relatively unco-
loured sound when clean, but starts to “snarl” beautifully when pushed into overdrive.
Its highly desirable “snarl” is rich with harmonic content and cranking this puppy up
will produce those classic, old rockabilly and rock “n” roll sounds of the ’50s and ’60s,
at the drop of a 10 gallon hat - especially when a single coil pickup is used.
Original’s tube compliment: 1 x 12AY7, 1 x 12AX7s in the preamp, 1 x
5Y3GT rectifier, 2 x 6V6s in the power amp.
16. TWEED 4X10 (TWD 4X10)
The 4x10 combo we modelled here was built in 1959 and originally intended for
bass guitar. This said, six-stringers were quick to embrace its smooth-yet-cutting
overdrive which is perfect for R&B (rhythm “n” blues) guitar. TWEED 4x10 is also
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 ‘em.
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.
“What is sag?” Do I hear you ask? Well, crank the Gain and VR GAIN controls on
this model, dig in hard with your pick and you’ll soon find out! Can you hear how the
note literally “sags” when you first hit it and then it opens up? That’s sag, geddit?
TONAL NOTE: Just like on the original, the Middle and Treble control of TWEED
4x10 are highly interactive and high settings of the Middle control automatically add
treble to your sound. As a result, you may want to turn down the Treble control as a
counter measure. Conversely, low Middle settings reduce treble so you might want
to crank the Treble a little more in such instances.
Original’s tube compliment: 1 x 12AY7, 2 x 12AX7s in the preamp, 1x GZ34
rectifier, 2 x 5881s in the power amp.
