"The AudioWeevil08 was hand-built in small quantities by Bug Brand Audio Electronics in Bristol and released in October 2008. The units cost £198 and all sold out almost immediately.

Building on the success of the Weevil08, the AudioWeevil08 builds even more features (see the block diagram above) and is both a synth-sound generator and an audio processor - with the usual Bug Brand chaos possibilities thrown in too!

Features

Dark green, slope-mounted case
Battery power only (due to the touch controls) - running off 6 AA batteries in the panel compartment mounted underneath. Bug Brand state that the battery life should be at least forty hours with decent batteries (including rechargeables).
1/4" mono output jack
Audio Input through a CMOS Overdrive/Distortion - a powerful input (1/4" mono jack) suitable for guitar or line levels. There are two levels of drive offering clean or distorted sounds. The distortion crunches really nicely!
Variable Response Wasp-style Filter - the filtering on the AudioWeevil is now full of character! Based on the famous old-school Wasp synth and offering variable Resonance / Q, Cutoff + LFO Modulation and Low/Band/Highpass outputs. There's a mixer going into it for balancing the Thru (Audio Input) and Ring (Weevil Sonics). There's also an output level control before 1/4" mono output jack.
Twin Oscillator Weevil Heart - this is the screechy ringmod centre of synthesis with many features. There are two lo-fi square wave oscillators (one with LFO modulation) with Hi / Lo rate ranges which feed into a quasi-ringmod. The 2nd osc can be switched over to accept the squared audio input for weird-assed ringmod processing. Added onto this are controls for: Power Starvation (with Stable or Instable modes), Ringmod Feedback (with three way routing switch) and an output Comparator to give stable levels even when starved.
Modulation LFO - Osc1 and the Filter can be modulated by the wide-range tri/saw LFO. The two rate ranges offer modulation from superslow to audiorate and the waveform is switchable from Saw to Triangle to Ramp. There are independent modulation depth controls for the Osc and Filter.
Screen printed Frontpanel with Contact Points - the professional frontpanel labels all functions clearly (13 dials, 10 switches) and presents a total of 16 body contact points allowing touchy chaos control of the machine - lick your fingers!
There can often be a bit of weevil-signal feedthrough to the audio input even with the Ring mix turned right down. This is most apparent with high input gains, but various settings can minimize any effects.

Please note: This is not a 'normal' musical instrument - have a listen to these demo mp3s (recorded straight with no effects) for an idea of the sounds the AudioWeevil08 is capable of:

Sonics just from the internals
Guitar Ebow drone process
TR606 Drum-machine process
