VT Bass 1969, an Ov rvi w

Th VT Bass 1969 bass amp h ad is a 2-chann l, 2-rackspac adaptation of

its p dal count rpart, th SansAmp Charact r S ri s VT Bass. Th h art of

th VT Bass 1969 is th analog warmth of th SansAmp mulation circuitry

that was d sign d to r cr at th pow rful ton s of Amp g®-styl stacks.

Each chann l f atur s a pow rful 3-band

activ

EQ s ction and a full-rang

Driv control to dial in your d sir d ton . Th uniqu , continuously-variabl

Charact r control mov s s aml ss b tw n d cad s of diff r nt voicings. It

alt rs th ntir sonic structur of th sound, from thick flip-top funk, to

indi rock snarl, to d p t ctonic distortion.

For studio and liv applications, our propri tary, 100% analog SansAmp

Tub Amplifi r Emulation t chnology nabl s you to go straight into th

mix r of a r cord r or PA syst m via th XLR Dir ct Output.

Th includ d Footswitch furth r xpands th VT Bass 1969’s capabiliti s. In

addition to b ing abl to r mot ly chang chann ls, th r is a MUTE switch

which allows you to sil ntly tun your instrum nt, and a MIX function to

simultan ously

ngag both chann ls, yi lding 3 footswitchabl sounds.

Th VT Bass 1969 off rs bootylicious ton s for f arl ss pro play rs y arning

to jump ship from th status quo.

FRONT PANEL

Th VT Bass 1969 is d sign d with active controls, which boost and cut, rath r than

traditional passiv controls which only cut. This ff ctiv ly doubl s many of th con-

trol’s capabiliti s, giving you a much larg r rang of adjustability and, ultimat ly,

mor vari ty. It should b not d that you n d not n c ssarily s t v rything at max

to achi v maximum r sults. As you xp rim nt and b com familiar with th int rr -

lationship of th controls, you’ll asily b abl to customiz your own sounds.

Chann l S l ctor Switch

Manually switch s b tw n chann ls wh n th r ’s no cabl plugg d into th r ar

pan l Footswitch jack. To r mot ly chang chann ls, us th includ d Footswitch or

any standard passiv footswitch. It will ov rrid th manual s l ctor switch. (For

mor information, r f r to pag 8.)

Gain

A 10dB gain boost to s t up th pr -amp for diff r nt pickups.

For xampl , with low r output passiv pickups, you can hav

punchi r sounds with Gain ngag d. Conv rs ly, with high r

output activ pickups, you can hav a cl an r sound with

Gain dis ngag d. Of cours , you can also obtain ov r-th -top

distortion by using high output pickups with Gain ngag d.

Input Jack

Faithful to th original d signs of traditional tub amplifi rs, this 1/4" Input is high

imp danc 1MΩ. Th typically additional low s nsitivity input, how v r, is not n d d

du to th Gain switch.

GUIDE TO CONTROLS

Driv

Adjusts th ov rall amount of gain and ov rdriv , similar to wh n th output s ction

of a tub amp is b ing push d. Th first half of th rotation will incr as th volum

as w ll as th ov rdriv .

Bass, Mid and Tr bl

This pow rful EQ s ction is lik having a studio mixing board at your fing rtips. Bass,

Mid and Tr bl ar activ ton controls that cut or boost ±12dB from unity gain at 12

o’clock. Bass is tun d to 125 Hz; Mid is tun d to 12dB @ 500 Hz; Tr bl fr qu ncy is

3.2 kHz.

Charact r

Sw ps through an ntir rang of tonal possibiliti s associat d with th Amp g®-

styl family of amplifi rs. In addition to modifying th fr qu ncy r spons , th

Charact r control also influ nc s th attack and driv that ar charact ristic to this

particular amplifi r styl . Th r for , you may n d to adjust your gain and ton s t-

tings aft r tw aking th Charact r control.

L v l

Acts as a mast r volum and is int ractiv with th Driv control. For cl an sounds,

s t L v l at max and control th ov rall l v l with th Driv control. For dirty sounds,

us Driv to s t up th ov rall amount of distortion and L v l for th ov rall output.
