Originally a microphone stand with a build in rhythm
box in the base and a microphone with voicechanger and light that
blinks to the beat. The microphone stand tubes and holder was missing
when I bought it at a flea market.
The manufacturers logo on the bottom reads "SBS", which
gave me the idea for the new name.
The middle button at the front starts and stops the rhythm. With
the rhythm running the two larger buttons triggers fill-in variations.
When the rhythm is off they trigger hi-hat and floor tom sounds.
On the side of the box are two minijack sockets, intended for pedal
switches, that can be connected to trigger bass- and snare drum
sounds and two more rhythm fills. I have later got one such pedal
with another unit.
Finally on the the main unit theres a volume dial with on/off-function
and a pilot LED.The two small buttons on the microphone are one
that turns the voice changer on/off, and one that cycles through
five different flanger and pitchshift voice changer effects.
Circuit bends:
Pitch/speed: the pitchresistor has been replaced with
a potentiometer. Now variable from very slow and deep, to superfast
and highpitched.
LDR pitch bend: A light dependent resistor (LDR) is
placed at the bottom of the hole that held the microphone stand.
By using handgestures over it, or otherwise altering the amount
of light that reaches the LDR, sweeping pitch/speed changes can
be made. With the three-position swith the LDR can be switced on
in either serial or parrallel connection to the pitch/speed potentiometeret.
Extra drumbuttons: Two pushbuttons have been connected
to the two aux. trigger inputs, so you can trigger the bass- and
snaredrum sounds, and two more rhythm variations, without adding
external equipment. The aux. inputs can still be used.
Microphone cut out switch: Shuts
off the microphone. Usefull to prevent unwanted feedback. (deliberate
feedback, though, using the voice changer is the coolest weapons
of the Sonic Battle Station)
Line out: Mini-jack socket
for line out. Since the picture was taken a 3-position switch has
been added to switch the output between line out, speaker or both
simultaneously, the latter adding the ability to work with microphone
feedback while using line out.
