AMT LegendAmps-2 Preamp Effects

General Information

Two-channel LA-2 series preamp effects are designed to produce clean and overdriven guitar sound within a variety of guitar channel organization. The basic concept of the series is "your own sound in your pocket."  LA-2 incorporates original circuit designs developed by the specialists of AMT, which allow to obtain bright and rich sound in the style of the original tube overdrives using low-voltage (9V) power and low current consumption.

The distinctive feature of the series is the presence of three outputs intended for implementation of basic types of channels organization:
• direct connection to guitar system power amp;
• connection to "clean" channel of a guitar combo or amp;
• direct connection to a mixer.
 
All three outputs can be used simultaneously!, thus fully carrying out its functions and not interfering with each other.
When connected to the amp or a mixer La-2 acts as a two-channel preamp providing switch between clean and overdriven channels by means of a  footswitch. CLEAN channel is universal for all models of the series and sounds in the style of classic Fender amps.
When using LA-2 in effect mode the "clean" channel of an external amplifier or a combo is used. Please be aware that the used combo or amplifier largely determines the resulting sound.
When in effect mode the series uses "partial" active bypass, which reduces the need to minimize the length of used cables and retains the original sound of the instrument when the effect is off. 

Controls

LA-2 series preamps are easy to use due to the small number of controls.
The sensitivity of channels is defined by the position CLEAN GAIN and DRIVE GAIN controls. Different models of the series have different overall drive-channel sensitivity corresponding to the sensitivity of the emulated overdrive.
TREBLE, MIDDLE, BASS controls provide adjustable high, middle and lower frequencies of Drive channel. The button switch like Clean Mid-Boost enables selection of tonal ratio from among mid, high and low frequencies of the preamp’s "clean" channel. Clean Gain and Clean Mid-Boost controls have no effect on the sound passing through the bypass in effect mode!
The output signal level is determined by the position LEVEL control and when set to 13 hours provides standard - 10dB level. The output signal level at the maximum control position reaches + 8 dB, so use this position only if you want to overdrive the input circuits of your combo or obtain additional overdrive for the amp. 

Individual features of the effects

The series preamps allow the performers to get a wide range of legendary tube amplifiers sounds.
P-2. Preamp is able to shape perhaps the most aggressive of the entire line sound generated by entire 6 stages similar to preamp section of Peavey 5150, 6505 amplifiers. The ultimate saturation with harmonics and richness is the sound of P-2 in a nutshell.
S-2. In the early 90's Mike Soldano created the amp, which later became a kind of a standard for metal sound realized with variations in Lead channels of various amplifiers (Soldano, Mesa / Boogie Rectifier, H & K Triamp). The common sound basis of these amplifiers was the 5-stage preamp, whose solid and bright sound is reproduced by this model.
R-2. Rectifier series amps by Mesa / Boogie is yet another benchmark in modern sound that simply cannot be ignored. A close relative of Soldano, it nevertheless has its own special character, the main features of which we tried to implement in R-2.
VT-2. The concept of VHT amps Lead channels is a sort of hollow roaring overdrive, whose character was reproduced by AMT engineers in VT-2 preamp.
B-2. Among the funs of contemporary sound there are many of who prefer a slightly refined but at the same time fascinating sound of Sharp channel of Bogner / Hafler TG, whose cold aggressiveness is conveyed by B-2 preamp.
E-2.  E-drive effect reproduces the main features of Engl overdrives. Engl amplifiers form a special contemporary sound branch. Convex and at the same time German-like rigorous character is reproduced by the four heated up to the full preamp stages.
M-2. Classic Marshall JCM800 mid-gain overdrive became popular in the 1980s. Its preamp section provides rich opportunities for a wide range of overdrive gain. M-2 shapes the structure of overdriven sound characteristic of JSM800 while maintaining ease at small gain and increased density at maximum values.
O-2.  Moderate-gain amps such as Orange are favored by fans of velvet and sparkling sound, the one we tried to reproduce with special warmness in O-2 model. C-2.  This preamp is able to emulate the unique sound of Engl's third cousin Cornford characterized by clear tone, diversity and minimalism. One C-2 drive channel provides wide overdrive range from slight crunch to biting high gain.
K-2. The pedal offers emulation of Krank amps custom sound. The sound of K-2 is  dense dryish high gain drive with a wide range of the channel working sensitivity which can satisfy the multiple fans of Dimebag Darrell.
