UNDERSTANDING THE BETA BASS PEDAL
The Beta Bass Pedal runs on an external 9VAC power adaptor and internally multiplies
the 9VAC to produce a +/- 15 volt power supply. This means the Beta Bass provides true
professional internal headroom not a typical 9 volt DC swing of other Bass guitar pedals.
The input signal is buffered and connected to the input of the clean
PREAMP
. The clean
preamp includes an input gain block to trim the Bass Guitar level so as to avoid
overdriving the Beta Bass Pedal at any point in the signal chain, a shelving bass and
treble control and dual mid frequency semi parameteric equalizers which includes a
boost/cut control plus frequency sweep, which will be described in more detail in the
PREAMP section. The output of the EQ section feeds the input of the Exciter circuit
followed by the Distortion circuit followed by the Decimator / Compression VCA and then
the Master Output Level. The Compression and Decimator level detection circuits are
reading the direct Bass Guitar Input which allows the Decimator to function like our G
String pedal. This means adjustements in the EQ, EXCITER COMPRESSOR and
DISTORTION will not require any adjustment of the Decimator Threshold control. You
can also switch ON and OFF these functions without any need to adjust the noise
reduction threshold. The Bass Exciter is a phase manipulation Exciter which allows
subtle mid-range shaping to help ehnance the midrange and provide extra separation of
the Bass from other instruments. The Compression circuit is designed to provide
amazingly smooth compression and keeps a consistant Bass level without squashing the
dynamics. The compression circuit is designed to provide “MAKE UP GAIN” when using
compression. This brings the final output level up based on the amount of compression
or gain reduction being used. The Distortion circuit allows a MIX between the clean
preamp output and a Bass Distortion circuit. This allows the player to add subtle crunch
to full blown distortion based on player prefference. The Master output Level controls
both stage level via ¼ ouptut and Balance Output to feed a front of house mix.
