AMT Bass Crunch BC-1 — 2-channel JFET bass guitar preamp (w/o power supply!)

ABOUT THE PRODUCT

The AMT Electronics BC-1 «Bass Crunch» is one of the most versatile bass guitar preamps on the market in a such small size.

The preamp has been built on the basis of the custom technology by АМТ using JFET emulation of the vacuum tube range clipping. The wide adjustment range in combination with rich functional possibilities that can only be found in a stomp box have considerably increased the preamp versatility.

The BC-1 preamp is based on a two-channel circuit.

► CLEAN CHANNEL

The CLEAN channel shapes the classic bass guitar sound characteristic for «old» amplifiers and allows both velvet transparent sound and slight compressed overdrive depending on the position of Gain control.

► DRIVE CHANNEL

The DRIVE channel contains a number of over amplification stages and is intended for obtaining the modern sound from clean to totally overdriven one.

The High Mode provides additional possibilities in terms of the range enrichment towards higher sound density and aggressiveness.

The adjustable 3-position mid-range filter combined with deep adjustments along the frequency ranges offer a musician its rich possibilities related to shaping of the overdriven tone range.
