Shea Leffler / Heavy Audio Research

Specialist violinist, Multi-instrumentalist, Composer, Producer


I make lots of noise, and I would love to make noise for your project too.

My name is Shea (or sleffy) and I'm a multi-instrumentalist, composer, producer and audio engineer. I'm a classically trained violinist but I also specialize in 7-string electric violin, an instrument which is rare enough that for most intents and purposes it doesn't really exist. You can find a short sample of my work below, as well as a playlist containing longer/full versions of those tracks.

If you are interested in commissioning me, please take a look at my commissions page. If you would like to contact me for other reasons or just to chat, you can just head straight over here for my contact info. I hope to hear from you!

Feel free to join my Discord if you'd like to chat or talk music tech/production/research with like-minded people:

Using Impulse Responses with Electric Bowed Strings

Why you might want to use an acoustic instrument impulse response with your electric violin, viola, or cello.

Speaking as a classical violinist when I first heard a solid-body all-electric violin (not electro-acoustic) I was pretty fucking disappointed with the sound.

Testing New Violin/Cello Impulse Responses (2020-8-8)

Comparing my old custom violin impulse response (IR) against the new 3SigmaAudio electric bowed strings IRs.

Recently, 3SigmaAudio (3SA) updated their bowed strings impulse response packs to include impulse responses (IRs) intended for full-electric instruments. Previously, they were intended for acoustic-electric only. However, I am a grade-A certified stubborn dumbass who would never let that stop me, so I've long since been using their acoustic-electric impulses and heavily modified them for my violin. Today though, I finally got around to trying out the new versions.
