Robot Assassin Tube Overdrive/modulation/pitch&octave |
Finished a couple of new guitar pedals-
Robot Assassin from above |
One is the 'Robot Assassin v.2', a tube overdrive w pitch & modulation-which can be used for vocals as well as for guitar. I'll be making a version for each, with the Vocal version having a slightly different tone stack (the 'normal' sound before changing tone via a control will have different frequencies emphasized/dropped, and the tone controls will affect different frequencies more suited to voice than guitar) from the guitar version, and the tone controls & switches will be different for both as well.
Psycho-Delic - 1st prototype. Could BARELY fit all the controls ! |
The original has a delay which can be set to almost infinite delay (basically set to loop), with the amount of feedback and the on/off of the feedback potentially controlled by the second footswitch-which is a momentary off/on one. Meaning you can send the feedback control to the switch, and if you have the feedback control turned up, it will simply loop the entire time your foot is on the switch..alternately you can set the feedback to turn on itself and use the footswitch to control how crazy it gets. The other option with the second footswitch is to set it so that you can modify the pitch of the delay with it-so that the slapback or echo, etc pttch dives down or squeels up.
The pedal also has a LFO with shrpness, shape, frequency, speed, and depth controls which can be switched from directly intersecting the delay circuit to replacing the original delay depth pot (knob). The power switch of the LFO also activates a LED (red in the 2 prototypes) which flashes in sync with the lfo's cycling frequency.
All of the sound coming from the Delay AND LFO (if its powered up) can be sent straight out, or shunted to the Fuzz section of the circuit. That switch also powers on the Fuzz at the same time, activating a differently colored LFO (white in the prototypes). The Fuzz has two channels- a FET buzz/fuzz, which can be set to be either generally fairly clean and not heavily distort the sound..or can be set to so heavily garble the sound that the guitar will sound more like a buzzing scitar or metal sawblade, and a Silicon/Germanium Fuzz which can go from lightly adding some dirt to a throwing the delayed sound into a screaming dust devil of insanity. Both channels have individual gains and the S/G fuzz has multiple other controls that : turn the diode clipping off/on, alter the eq-boosting the high or low end, change the fuzz from Silicon to Germanium, and change the amount of fuzz as well as its thickness. The other FET fuzz channel has two subchannels/substages- a buzz and a fuzz, both of which have various standard controls with one overall main gain as well as a low-end boost switch. Both Fuzz (FET and Vint S/G) channels have a 'Mix' control that precedes them so that the sound out from the delay can be sent from 0-100% to either channel, allowing the user to choose to balance both or use either primarily with just a touch of the other to color the sound.
As you can see i n the photos-all this leaves the pedal with perhaps too many knobs, controls, switches, and lights. Unless you're like a lot of Synth-heads (like me) can be-who like tweeking the sound of something and enjoy having a HUGE amount of possibility to MANGLE your sound into a Hellstorm of Insanity-you might want to wait for the light version.
Either way, check out the short & sweet video of it in action in the lab:
