The V2's Are Here!

What’s new about the V2’s? String Theory EFX has been working hard over the last few months to make the KE/64 and Tevatron more pedalboard friendly, reduce production time and lower the cost, all while keeping the same great sound of each pedal intact. Both pedals now feature printed circuit boards and powder coated enclosures with UV printed graphics to drastically reduce the labor intensive practice of point-to-point wiring each circuit and acid etching each enclosure that the original effects featured. The Tevatron Fuzz and KE/64 Overdrive are still 100% handwired one at a time, using the exact same through-hole circuit components as the originals to retain the same sound and feel of the original versions of the pedals. The Tevatron Fuzz is also now available with the option of coming with either a hand selected NOS germanium transistor or a silicon transistor.

Both pedals from String Theory EFX are available now and can be purchased directly from our SHOP . The KE/64 Overdrive is available for $165 and the Tevatron Fuzz starts at $180 equipped with the silicon transistor and $190 equipped with a NOS germanium transistor.


Hello Everyone!

I’ve had some inquires lately about the status of String Theory EFX.

String Theory EFX won’t be going anywhere anytime soon. =) Things have been quiet around the website over the last few months, but behind the scenes I have been very busy. I hope that i’ll soon be able to share with everyone what I’ve been working on.

Stay Tuned!


Ordering Update

Just wanted to give a small update about ordering a pedal directly from String Theory EFX.

From now on, I will no longer be doing pre-sale orders. When I build a pedal(s) and have them available for sale I will update the SHOP page.

I may do an email list in the future to keep everyone in the loop when I have pedals available, but for now please keep track of the web shop or the String Theory EFX Facebook page for product updates.



Hello All!

Michael here from STRING THEORY EFX. 

Welcome to our newly updated website! There's been a lot going on around here lately and I thought I'd give an update.

The KE/64 OVERDRIVE has a new case and a new lower price. While I really liked the original folded aluminum case of the the KE/64, they were very time consuming and difficult to finish and acid etch, along with being quite large. The new pedal enclosures have allowed me to dramatically cut down the production time of the KE/64 and with that comes a lower price. :) I also really like the new look of the smaller case and hope you do to.

The TEVATRON FUZZ is available NOW!!! It was a long process to develop this pedal. I tested out many fuzz circuits before coming up with the design that led me to the TEVATRON. This fuzz sounds absolutely massive! While the demo video I recorded recently does a good job of showing off how it sounds, it doesn't compare to playing it in person.  To quote from Ferris Bueller's Day Off, "It is so choice. If you have the means, I highly recommend picking one up."

The website has had major changes over the last few days. The layout is much cleaner and simpler. There are features like the SHOP where you can now buy a pedal directly through the website.

Thanks for visiting STRING THEORY EFX!
