the teaspoon is a lo-fi instant playback looping
audio sampler designed to achieve the classic glitching
/ stuttering / skipping effect by pushing a single
button. this version is a limited run of fifteen designed
with the AUDIOBULB
RECORDS logo and trademark orange
and black.
PLEASE NOTE :::
i know there is a video of the teaspoon
processing control voltage signals as if they were
audio but this was never even a consideration during
the design, its just a byproduct of misuse, not a feature.
because of this i did not have any reason to include
over voltage protection so if you ever exceed +/-3v
you will destroy the chip and this is not covered under
the warranty.
there also seems to be some common
confusion where people think the rear center jack is
a CV input. it is NOT, its a DC power jack. its pretty
obvious in the photos below, but i think that some
people are not scrolling all the way down to see them.
there are not any CV features in this device in any
way
gain: this is the
control for the pre amp that is in front of the sampler
which is strong enough to allow you to plug a guitar
directly into it and get a line level output. at lower
settings it works as a buffer for line level inputs
as usual and it can obviously be used to overdrive
the input or with smaller adjustments you can control
the over all dynamics if thats your thing.
time: this is the
sample length / pitch adjustment. setting it to any
given location sets the length of time it will sample,
adjusting it just prior to pushing the button will
allow you to alter the pitch/speed of the incoming
audio that is sampled. as well adjusting it after pressing
the button will allow you to alter the pitch/speed
of the playback.
out: this is the
output volume control
push button: this
is a nice heavy duty switchcraft momentary pushbutton
that triggers playback of the sampler, which is constantly
sampling the input even after the button is pressed.
this means that every single playback cycle is a rerecording
of the output and each one will gradually degenerate
especially at the lower sample rate of the slower speeds.
as soon as you release it its immediately sampling
the incoming audio again and the previous sample is
being over-written ( but if you quickly switch back
to playback you can then interrupt the recording and
hear bits of the old that have yet to be overwritten
now cut together with the new ). also if you sweep
the time control far up or down during playback it
will then be re-sampling the higher/ lower pitched
sound and when returning to the original speed the
sound will be different, you can do this
over and over creating staticy grain clouds. please
note there is no "bypass" switch.
just not having this button pushed is the bypass (
not true bypass)
power switch : just
a power toggle switch indicated but the led on top. note: i
had to do some unusual things to get more pitch range
out of this design so if you try to power it up with
the time set to the highest possible setting it will
not boot correctly. just turn the time down a couple
notches and reboot to remedy this. just a minor inconvenience
9v dc jack : standard
DC power supply here. anything from 9v to around 15v
is fine. there is an internal regulator to keep things
safe
in / out jacks : mono
in and out marked with arrows on the top
