14. BLACK 2x12
The dual channel, blackfaced beauty we modeled here is considered a “must-
have” 2x12 combo for country and blues players, and rightfully so - after all, its
celebrated clean sound is very tight ‘n’ twangy, with a deep, taut, piano-like bass.
Pristine clean tones aside, BLACK 2x12 is also capable of producing that
classic Chicago blues tone - especially with single coil pickups. In keeping with the
original, when pushed hard the bass on our model tends to crumble. So, to emu-
late this classic, BLACK 2x12 overdrive, here’s what you dial in on your Val-
vetronix: full GAIN, no BASS, full MIDDLE and set TREBLE to taste. Because the
EQ network of BLACK 2x12 lies before the main gain stage of its preamp y’see,
pushing the mids in this way emphasizes the distortion in that frequency range
and the result is a lovely, singing blues tone.
As already mentioned elsewhere, the original amp doesn’t have a Presence
control but does have a Bright Switch. The PRESENCE control on your AD60VT/
AD120VT emulates this switch when “off” and “on,” plus all points in-between!
Original’s tube compliment: 4 x 12AX7s & 2 x 12AT7 (a.k.a. ECC81) in
preamp, 4 x 6L6s in power amp.
TONAL HINT: BLACK 2x12 is the perfect partner for ACOUSTIC (Acoustic
Guitar Simulator) in the Pedal section.
15. TWEED 1x12
The original we modeled 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 mim-
icked by using the Valvetronix’s TREBLE, MIDDLE and BASS EQ network as fol-
lows:
Original Tone control turned all the way down (off) = BASS on full; TRE-
BLE 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 “neu-
tral” when “off,” but can be used to add “extra” sparkle and cut to the model if
you so wish.
