INTRODUCTION

Legend Amps B-1 GUITAR PREAMP is intended for studio recording and live

shows.

“AMT Legend Amps” is a novelty revolutionary series of 1-channel

JFET preamps from AMT Electronics based on the completely new

approach to the guitar sound shaping.

The new series of guitar preamps is based on the technology using analog modeling

of physical processes occurring in the real vacuum triode during guitar signal

limitation.

It was realized due to the use of original circuitry design.

The overdrive channels construction corresponds to the processes occurring in real

tube-based devices.

Thanks to that we achieved formation of limitation, dynamics and range similar to

popular tube amplifiers.

While having minimum size and power consumption inherent in semi-conductor

elements, the effects of AMT Legend amps series possess a number of unique

properties characteristic to authentic tube preamps and amplifiers:

9 The preamps of AMT Legend Amps series provide great playing dynamics

characteristic to tube devices.

9 With limitation range similar to tube the effects of the series offer tremendous

density and power of sound. Using AMT Legend Amps you won’t feel the

necessity to cut out the most informative mid-frequencies that provide good

readability of your guitar in a mix.

9 AMT Legend preamps like tube ones provide gradual increase in the number

of limiting cascades with sensitivity enhancement.

9 The preamps of the series use passive circuits of tone formation fully

corresponding to the adjustments of original tube overdrives.

9 High output level of AMT Legend Amps effects (+10dB at maximum Level)

corresponds to tube preamps output levels. In this way you have the

adjustable signal level which allows to connect the preamp to any input

(RETURN, DIRECT, LINE etc.), including INPUT POWER AMP.

Architecture and features of AMT Legend Amps series preamps:

9 The preamps of the series are single-channel devices with passive bypass.

9 Legend amps have two outputs: direct OUT of the preamp and a separate

CAB.SIM line output.

The sound features of guitar preamps of “AMT Legend Amps” series:

AMT Legend Amps B-1

This preamp is intended for the admirers of a "clanking" sound with elastic punch.

Legend Amps B-1 emulates Sharp channel of such legend as Bogner Triple Giant.

AMT Legend Amps B-1 has the same sharpness, the same exactingness of sound

production, the same dynamism and the same sound brightness as the original.

AMT Legend Amps M-1

It emulates the "forefather" of the majority of amplifiers created for heavy styles,

legendary Marshall JCM800. As well as the legendary "forefather", AMT Legend

Amps M-1 is perfectly on friendly terms with boosters.

AMT Legend Amps P-1

This device emulates one of the most esteemed one for its super heavy sound -

Peavey 5150. The sound of AMT Legend Amps P-1 is monstrous density and

aggression and huge amount of gain.

AMT Legend Amps R-1

This device embodies all the power and grace of Red-channel overdrive used in one

of the most popular hi-gain amps by Mesa Boogie.

AMT Legend Amps S-1

The device is intended for the production of sound peculiar to «drive» channels of

Soldano amps. It is distinguished by specific type of overdrive: open, wide and at the

same time tough and dynamic.

AMT Legend Amps F-1

The basic sounds of AMT F-1 are classic amps of Fender Twin series. AMT F-1 offer

crystal clear sound with slight warm overdrive at high sensitivity.

AMT F-1 is a pioneer of the basic modules of the entire AMT LA series.

You can build around AMT F-1 your own complex of multi-channel preamp

consisting of AMT LA mono channels: P-1, B-1, M-1, R-1, S-1. The series is

constantly expanding to provide you with unique 100% analog tool forming the

sound of your guitar.

AMT F-1 is supplied with power adapter (unlike the other pedals of the series).

CAUTION!

The preamps of AMT Legend Amps series like many other

top-class devices are sensitive to power adapters’ quality.

We urgently recommend using either 9V battery 6F22 or the quality

adapter such as AC/DC Adapter SA09DC-9V 1,11A or

AC/DC Adapter SA12DC-12V 1,25A.

Before you start

For the purpose of transportation the device was carefully packed by the

manufacturer. However, if cardboard packaging is damaged, it is necessary to

check the device for the presence of external damages.

¾ In case of damages do not send the device to us, but

inform the seller and transport agency since otherwise you

lose the right to damage compensation.

¾ In order to avoid damages during storage and

transportation always use original packaging.

¾ Do not allow children to play with the device and

packaging materials.

¾ Please recycle all packaging materials in the way harmless

to environment.

¾ In order to avoid the device overheating provide sufficient

air flow, do not cover and do not place it near other heat-

generating devices.

¾ Operating the device next to powerful radio transmitters

and sources of high-frequency signals can lead to

significant sound distortion. In this case increase the

distance between the device and the transmitter and use

the screened cables for all interconnections.

WARNING!

Please be aware that high sound volume can harm your hearing

and / or to damage the speakers of your PA system. Before

switching the device on turn the controls "Volume" into

extreme left position (counter-clockwise). Always try to adhere

to moderate level of volume.
