Pedal description (by Lovetone)
The MEATBALL™ is an amazing envelope follower/triggered filter - the funky blue alternative to a high fibre diet that has put a smile on (or at least taken the frown off) a lot of faces! Because of the large number of controls, and because changing the position of any one affects the way in which the others will interact, this offers a truly vast array of sound possibilities (from the sublest effects to frightening untamed excesses!) and means that the Meatball™ can be "tuned in" to dance the most intimate tango without treading on your toes or just wave its arms in the air and let it all hang out. (The filter frequencies can also be tuned precisely to allow laser guided goosing of high gain distortion). While the Meatball™ is capable of the most gratuitous "auto-wah" funk abuse and visits the promised land of Bootsy "You won't need any spaghetti with this Meatball it's real phat" for fun, this represents but a mere fraction of its potential which includes totally unique new sounds. The large frequency and dynamic range makes it equally suitable for bass, guitar, keyboards/synths, samplers and general studio use - in fact any audio signal whether a single sound source or programme material.
By treating simple waveforms it can become an analogue synth in its own right, or it can be used as an aural exciter to add sparkle and depth particularly to lifeless samples. The external trigger facility enables the filter to be triggered by a completely separate audio source which can be another instrument, pulse or click or even touching a lead connected to the input! A great way to exploit this is to use one aux send on your mixer for the sound source and another one for the trigger so you can literally trigger anything with anything which as you can imagine can give rise to some pretty freaky effects.

Technical info (by Lovetone)
Featuring:
- Sensitivity control
- Attack and Decay controls
- Range control (can be used to fine-tune the frequency response and create subtle effects)
- Resonance control
- Blend which mixes straight signal with effect creating a whole new palette of sounds.
- Pedal facility (allows the use of a standard passive volume pedal to create wah-type effects)
- FX loop - insert octaves and distortion for some real 70's cheese, or use for external trigger facility
- Up and Down response curves
- High, Low, and Band-pass filter modes
- Four selectable filter frequency ranges
- Triggering off full or half bandwidth and trigger off (useful for instance as a static tone control or for adding or scooping tone with blend)
- LED showing filter response
- LED showing effect on/off

Modifications
- Voltage control: the Meatball will run with anything between 9V-12V DC. A simple mod is adding a control to the pedal to be able to select any voltage within that range (instead of having to chose between the two in your charger). You can even add a panel volt meter to display the exact voltage.
