Expression Modulator Pedal

LEWIS

Lewis is a LFO Expression Modulator utility stompbox to control your favorite guitar effect pedals, modular devices or synthesizers.

A loony exploratory utility tool that controls your favorite effect pedals or instruments via expression or CV input by using low frequency oscillation. This neat little stompbox includes 16 waveforms and offers different controls to shape them: Depth, Rate, Distort, Shift and Crush. Lewis also features an assignable expression control input that maps a secondary expression jack (to connect an expression foot pedal or another Lewis) to either the Depth or Rate control. Lewis can turn your filter effect pedal into a fuzz, or your delay into an arpeggiator. Or it provides an additional LFO for your single-LFO synthesizer. The possibilities are endless.

Lewis can do so much. Some of it may be expectable, some if it will knock your socks off. Depending on the Pedal or Instrument you connect to it, the effects will be vastly different. Read the manual to get yourself started.

FAQ

Which pedals are compatible with Lewis?

You can control any pedal or Instrument that offers an Expression or CV Input. The effects Lewis has on the connected Pedal or Instrument will be widely different, depending on the type of pedal/instrument and on which parameter you'll be controlling. Depending on the polarity of your connected Effect Pedal or Instrument, you may need to use Lewis' onboard switch to adapt the polarity.

To simplify things (and because it's fun), we call all compatible devices 'Clark'. Our favorite Clarks are: any Moog MF pedal, any pedal by Meris, the Pyramid by Earthquaker Devices, Tremotron by Stone Deaf and the awesome Prophet 6. It is important to know, that we cannot guarantee compatibility with every single pedal or instrument available, because some devices use a custom signal type to be externally controllable (e.g. Stone Deaf's PDF-2). If you're unsure, contact us.

How can I use Lewis in a live setting?

How you bring in Lewis into your live set is your choice all alone. Lewis' expression pedal input gives you an additional option in how you you use it in a set or a single song. For instance: by connecting your expression foot pedal to the depth parameter, you're able to fade in or out Lewis' effect on your chosen Clark (the stompbox connected to Lewis) whenever you want to. Lewis' strength of course is laying down a solid rhythm to build upon. You can turn your filter pedal into a Tremolo/Vibe for the verse, and deactivate it for the chorus to make it sound fuller automatically.

My Lewis doesn't work. What to do?

→ Check, if your Lewis is properly connected to a suitable power source.

→ Check, if your Lewis is engaged (big LED is glowing). If not, press the On/Off Switch to do so.

→ Check, if the polarity of your connected effects pedal or instrument is matched on your Lewis (onboard switch).

What expression pedal type can I use to control my Lewis?

You can use any expression pedal that either offers TRS or TSR polarity. Make sure, that the needed polarity is matched by your Lewis. Adjust the onboard polarity switch if necessary.
