Ixe2x80x99m fumbling around a lot in the video because Ixe2x80x99m trying in vain to operate the thing with both hands while filming it.
Basically the mods are:
-switched 1/4xe2x80x9d output jack
-reset button
-boost volume pot
-toggle on/off pitch control
-hi-pass effect (not really a hi-pass circuit, just two points that produce a similar-sounding result)
-toggle on/off four contact points
-xe2x80x9cboopxe2x80x9d feedback-like sound
-xe2x80x9crumblexe2x80x9d a different feedback-like sound
-xe2x80x9csqueakxe2x80x9d toggle on/off/on two different pots that either produce a sensitive to control sputtering sound or a more subtle sputter/volume attenuator, generally modulated with the xe2x80x9cboopxe2x80x9d pot and vice-versa... itxe2x80x99s hard to explain
Truthfully, the last two mods are hardly worth the effort; theyxe2x80x99re neat and all but difficult to predict. Plus one of the pots was a weird value which cost an outrageous amount of money, at least by pot standards.
The enclosure used to be a cd carrying case. Much easier to wo
rk with than a metal enclosure. My dad helped me make a hinge for it. Most of the parts used for this build (aside from the wires, knobs and most components) were recycled or bought secondhand.
