1. Introduction
Welcome to B!
Thank you for choosing the amp one out of the AER bottom-lineseries.
This series has been specially developed for the modern bass player
who values performance, versatility and easy handling.
Please take a few minutes to read through these instructions. We
want you to understand just what the amp one can do and how to
set it up so that you can get maximum benet out of it.
The amp one is an „all-rounder“, designed for the „Top 40“ bassist
who is used to switch between several styles and who sets value on
weight, dimensions and easy operation. The 10-inch high performance bass-loudspeaker supports this versatility whilst simultaneously adding some tube-like compression. The design of the power-amp
especially supports the impulse response and provides impressive po-
wer at short term, exceeding signicantly the specied 200 W on 8
ohm, which you can clearly hear.
Amp one is professionally and richly equipped and, of course, it produces the unmistakeable AER sound character. Technically speaking,
the amp one is designed for high-impact and extreme dynamics.
From the musical point of view, the bass combo is clear, differentiated, assertive, punchy and inspiring.
At this point we would like to thank Paul Sips for his „final bles-
sings“.
Read on and have fun with your amp one!
