In April of 2021, thiSHEAvyearth was created here in Portland, Oregon after the end of my previous endeavor Transmutation Devices. My career is in lighting by day but spend my nights/weekends designing amps and effect pedals for THE as well as a few other brands.

Over the previous years of creating modified clones, I decided that my goal for T.H.E. would be to create more unique builds and move some of my custom amplifier builds into production formats. While some might call it "too many knobs", THE builds are focused on maximum versatility so while exploring a certain tonal palette, each of us can find our sound.

Not sure what you might be looking for from my line? Hop over to my YouTube. I'm not the guitar player I once was because I rarely get to play lately (something I need to change) but you'll find introduction/knob turn videos from me as well as a Playlist called Pedal Demos that aggregates the known demos out there. These demos are also linked to each product page to help your decision. Still not sure? Reach out and chat about it.

Last thing, feel free to send me video or audio of what you're doing with your purchase. I love hearing how others use my designs. When possible hit me with a link or tag on social so I can share it back out. I don't actively market my product so demos from great people online and word of mouth is everything.

    Founder and designer.


    Coming on board in 2024, she has jumped in to help with everything from keeping track of the books, order fulfillment, and shipping.


    Keeping everyone on task and ensure maximum quality control, every supply restock comes through his department for inspection.


    The riff master general makes sure that when we are testing, it's not some weak ass riff. If he doesn't approve, it doesn't ship.



    You may notice that I do not include a lot of extra box candy and recycle packing material sent to me in my shipments in an effort to reduce some of the carbon footprint of this passion project.


    Everything is designed and built right here in the shop so sometimes order quantities or just life can cause a little bit of delay as I build to order. Due to this I try to offer maximum transparency through "Build Updates" on social media as well as webstore newsletter emails (but I promise not to spam you with email).
