The Zorg Effects Love Philter MKII is an analog envelope filter pedal, a filter pedal that goes well beyond the usual auto-wah. The maker describes it as three "modules" in one box: a low pass or high pass resonant filter, an envelope module with full controls on attack, release and polarity, and an LFO module. The filter is based on a filter chip used in the Oberheim synths of the 1980s1.
What it does
Because the three modules can be combined, RockBoard's PedalPedia says the Love Philter is not only an auto-wah or envelope filter, but also a wah-wah, an "ahw-ahw", an auto-ahw, a fixed low pass or high pass resonant filter, a two-stage phaser, a VCO, a "lazer gun" and more1. That range makes it a deeper alternative to a straightforward wah-wah pedal or a single-function phaser pedal.
On the filter's sound, the maker reports no loss in the bass band and a very little resonance raise when sweeping the filter up. Self-oscillation is possible, giving either a perfect sine at the beginning or an overdriven square when pushing the resonance further1.
The designer's note on the product page frames the intent: "This Love Philter is my first pedal made to recreate the fun of CV in/out pedals with an amount of controls high enough to challenge your creativity"1.
Control and connectivity
- Envelope module: full controls on attack, release and polarity1
- CV: nine CV in/out jacks1
- Expression: an expression pedal is available, allowing you to control almost all the parameters of the pedal1
The CV jacks and expression input put the MKII in the company of patchable, control-voltage-friendly designs. RockBoard's PedalPedia describes the Love Philter MKII as his first pedal made to recreate the fun of CV in/out pedals, with an amount of controls high enough to challenge your creativity1. Players interested in that approach may also want to look at the Zorg Effects Love Philter MKII, whose filter, per the maker, keeps the bass band intact, with no loss in the bass band and a very little resonnance raise when sweeping the filter up1.
Power
The Love Philter MKII runs on 9V DC, center negative, and draws 120mA1.
At 120mA, the pedal draws more current than many small filter pedals, so a supply output rated for that draw is worth having on the board.

Questions
Is the Zorg Love Philter MKII analog?
Yes. The circuit type is analog, according to the maker's product page. It is built around a resonant low pass or high pass filter based on a filter chip used in the Oberheim synths of the 1980s, and the maker reports no loss in the bass band and only a very little resonance raise when sweeping the filter up.
What power supply does the Love Philter MKII need?
The Love Philter MKII runs on 9V DC, center negative, and draws 120mA. That current draw is high enough that a standard low-output daisy-chain supply may not be the right match, so a supply rated to deliver at least 120mA on that output is the sensible choice.
Can you control the Love Philter MKII with an expression pedal?
Yes. An expression pedal is available, and the maker says it allows you to control almost all the parameters of the pedal. Alongside the expression input there are nine CV in/out jacks, extending the control options further.
What filter chip does the Love Philter MKII use?
The maker describes it as a low pass or high pass resonant filter based on a filter chip used in the Oberheim synths in the 1980s. That chip is the heart of the pedal's filter section, which can also self-oscillate, producing either a perfect sine at the beginning or an overdriven square when the resonance is pushed further.
