the beach is fun.   getting a speeding ticket, however, is not fun.   nor is paying the fine.

so, we’re selling off some old prototypes and leftover gadgets we have laying about.  all are in new condition.

prototype of the rebel scum (pictured left):   SOLD

top left knob is blend control.  top right knob is pulse width control.  middle knob is volume control.  switch on the right is for the range of the pulse width modulation.  switch on the left changes from blend control to a weird feedback loop effect (lower volume in this position).  powered by 9v center negative dc adapter (not included).  no battery option.

see rebel scum page for video sample.

first ever prototype of the rebel scum (pictured left):  now on eBay

from when we were going to call it the ion pulse.  no blend control.   left knob is volume control.  right knob is pulse width modulation.  switch on the side is for the range of the pulse width modulation.   powered by 9v center negative dc adapter (not included).  no battery option.

sounds like the rebel scum with blend control turned all the way to the right, so watch the rebel scum video to get an idea of what the pedal is like.

4 channel passive mixer/splitter (pictured left):  SOLD

used as a mixer there are four 1/4″ inputs.  each with its own volume control.  one 1/4″ output on the side.  there is no master volume knob.

to use as a splitter, input is on the side.  4 jacks on the bottom are the outputs.

passive = no power needed.  it also means that there will be volume loss.  volume drops more as more channels are used.

passive notch filter (pictured left) =  now on eBay

this is based on a project in craig anderton’s book “electronic projects for musicians.”   we built it just to see what it is like.  it’s a passive notch filter using an inductor and capacitors.  it cuts out selected frequencies from an audio signal.  the knob on the right is a rotary switch that selects the frequencies to be filtered out, the knob on the left controls the depth of the filtering effect.

the rotary switch has six positions: far left position bypasses the filter circuit, other positions select capacitors of different values. the toggle switch in the middle changes the value of the inductor. so you get a total of 10 different filter frequencies.

passive = requires no power source, but there is a drop in volume.

***we are also selling 5 contact mics at $13.50 US each and a shaker box w/ mute switch and low-pass filter for $40 US.  (sawtooth oscillator w/ lfo =  SOLD.)***

might have some more stuff to sell.  gotta go through some boxes to find it, though.

shipping costs depend on how much you buy and where you live.  but we’ll make it fair.
