A. AMP Models
5
6. UK 68P
This is based on the “High Treble” channel of a 4 input, 1968, 50 Watt, all-valve head. It doesn’t feature a Master Volume control so the best way to set it up
is to max out the volume! To achieve the same response as the original, remember to turn the VR GAIN control to maximum. The JamVOX works
EXACTLY like the original. So, wind the GAIN control all the way up and immerse yourself in an instantly recognizable, organic overdrive that responds
beautifully to the subtle dynamics of your playing. Rolling back your guitar ’s volume control results in a unique and highly usable clean sound.
Original’s valve compliment:
3 x ECC83s in the preamp, 2 x EL34s in the power amp.
7. UK ’80S
This is based on a 1983, all tube, single channel 100 Watt head that boasts a Master Volume control. Invariably played with its (preamp) Gain con-
trol cranked, this amp will provide a fat, roaring sound. Although UK ’80s became famous for its distinctive, cranium-crushing crunch, it isn’t
merely a “one trick pony” and neither is our model—just like the original, when you roll back your guitar’s volume knob you’ll get a bright, clean
sound that’s perfect for chord work and will cut through any mix.
Original’s valve compliment:
3 x ECC83s in the preamp, 4 x EL34s in the power amp.
8. UK ’90S
This model is based on the “lead” channel of a 100 Watt, dual channel head that is capable of so much preamp distortion it houses a Gain control
that goes all the way up to 20! This amp replaced UK ’80s and was developed to satisfy the ever-evolving rock guitarists’ insatiable lust for more
gain, features and flexibility.
Original’s valve compliment:
3 x ECC83s in the preamp, 4 x 5881s in the power amp.
9. UK MODERN
This is based on the High Gain channel of a modern, all-tube 100 Watter that is effectively a hybrid of the UK ’80s and UK ’90s amps. It combines the tone-
ful high gain preamp stage and modern features of UK ’90s with the unmistakable, “snarling” punch and girth the UK ’80s power stage had to of fer.
Original’s valve compliment:
4 x ECC83s in the preamp, 4 x EL34s in the power amp.
10. BLACK 2X12
The dual channel, BLACK 2X12’s clean sound is very tight “n” twangy, with a deep, taut, piano-like bass. When pushed hard the bass tends to
crumble. So, to emulate this classic, BLACK 2x12 overdrive, here’s what you dial in on your JamVOX: full GAIN and VR GAIN, not much BASS,
full MIDDLE and set TREBLE to taste. Because the EQ network of BLACK 2x12 lies before the main gain stage of its preamp, 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 orig-
inal amp doesn’t have a Presence control but does have a Bright Switch. The PRESENCE control on your JamVOX emulates this switch when “off”
and “on,” plus all points in-between!
Original’s tube compliment:
2 x 12AX7s & 2 x 7025s & 2 x 12AT7s (a.k.a. ECC81) in the preamp, 4 x 6L6s in the power amp.
TONAL HINT:
BLACK 2x12 is the perfect partner for ACOUSTIC (Acoustic Guitar Simulator) in the Pedal effect.
