AMT Bricks A-Bass - 1 channel tube guitar preamp (Alembic)

 INTRODUCTION

AMT Electronics presents the new X-Lead/X-Clean line of tube guitar preamplifiers. This line is a part of the AMT Bricks series of devices. The AMT Bricks series includes various devices (preamps, effect pedals, noise suppressors, cabinet simulators, controllers, pedalboards, etc.). Uniting the AMT Bricks series factor is their design and functional compatibility. Most of the devices of the series can be used both independently and together.

The AMT Bricks series and the X-Lead / X-Clean tube preamps’ line are expanding constantly. Small dimensions, versatility, and “adult” sound – under this motto the new line of pedals was created. The pedals are built depending on the number of amplification stages either entirely on vacuum triodes or on the hybrid Tube + Semiconductors technology.

 AMT Bricks A-Bass

AMT Bricks A-Bass - this device is based on the scheme of the legendary Alembic bass preamps line.

 Features:

• Small dimensions (Snickers size).
• The full set of regulation knobs (Gain, Treble, Middle, Bass, Volume), despite the compact design.
• The really high anode voltage (+250…300V).
• The implementation of either full tube or hybrid (tube + semiconductors) circuit design with efficient emulation of vacuum triode cascades by semiconductor components.
• Ability to use overloaded channels in preamp mode (connected to the Amp’s Return) or in the drive pedal mode (connected to the amp’s Input).
• The pedal can control other devices or be controlled by other devices. It has special CTRL A and CTRL B connectors.
• X-Lead/X-Clean preamps can be used as separate devices, as well as a group of preamps connected in a serial chain (both via the audio path and the control connectors CTRL A and CTRL B). In the latter case, turning on any preamp in the chain will turn off all other connected preamps, that is, they’ll be switched to TRUE BYPASS mode. Thus, without the use of any external devices, it is possible to implement a multichannel preamp from almost any reasonable number of preamps of the X-Lead/X-Clean line, switched by the “one of” rule.
• In addition, X-Lead / X-Clean preamps, along with other devices, can be used as part of an AMT Bricks pedalboard. Full information about the pedalboard will be presented later.
