WARWICK WA & BC SERIES BASS AMPLIFIERS

OWNER’S MANUAL

Classic sound with modern performance. Manufacturing techniques and component quality has improved drastically over

the last couple of decades. Noise and hum are no longer unavoidable side effects of great sound. So here we have recreated

the “Classic” 10 band graphic EQ powered Bass Amp with big, powerful, tight sound in a modern package. 

Our considerations in these amp designs were multifold and our objective is to provide:

An affordable amp for the serious up and coming musician.

A seasoned professional’s gig amp.

Here is a short explanation of the underlying design concepts.

CLASS-A CIRCUITRY

Class-A amplifiers are typically more linear and, as such, are less complex than other amplifier classes.

The amplifying element is biased so the device is always conducting to some extent. This means the amplifier is always

on, avoiding the problem of crossover distortion associated with class-AB and -B designs. 

LOW-Z CIRCUITRY

By lowering the impedance inside an electronic circuit you lower the amount of thermal noise. In an amp where you have

tone  controls  that  lift  mids  and  highs  a  considerable  amount,  proper  impedance  level  makes  the  difference  between

enduring audible annoying hiss, and enjoying a pleasant tonal experience.
