Mythos Pedals Hephaestus Fuzz Pedal


What was initially a limited model, the Hephaestus Variable Voltage Fuzz is now a standard model in mini form!

Sometimes you don’t know where a circuit will take you, such is the story with the Hephaestus. This fuzz box started life as the now legendary Jordan Bosstone, but as Zach attempted to make the pedal more useful he stumbled upon something he didn’t expect. The Bosstone circuit is a relatively simple circuit combining a NPN and PNP transistor pair to get some pretty great classic fuzz tones. However the variety of tones in the original units are fairly limited. Zach was bound and determined to find something more interesting and after poking and prodding we landed on something we think people may not expect. Enter the WARNING knob.

The WARNING knob on the face of the pedal does not control volume, it doesn’t control gain, it controls voltage feeding the circuit! When maxed out the circuit sounds like the best of the classic circuit, but as you turn the knob down and adjust the overall voltage entering the circuit. Once the knob hits 1 o’clock something magical happens, a sub octave begins to be introduced! When and where it appears will be very dependent on your guitar and amp setup but it creates a sub octave synth effect that is unlike anything we’ve ever tried from a simple analog device. Further reducing the voltage or WARNING knob will cause even more octave things to happen while reducing the overall gain of the circuit. Internally there is a master volume so you can adjust the overall output of the pedal. Be warned, this circuit is loud! From us the master will be set at 50% so as to not worry friends and family around you who may bear witness to the first riffs heard from this little red fuzz box.It’s weird, wacky, but most importantly it’s incredibly fun to play. We cannot seem to stop writing riffs on these pedals as we test them and we cannot wait to see what players come up with.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Makes For Quiet Rides
Model: 10 SqFt(0.95 SqM)
Comparable quality and performance to name brand competitor. It sticks on strong, easy to apply, and does make a difference in sound reduction. Turn your hollow shell sounding vehicle panels into solid sounding walls.

Must for subwoofers. True 2mm spec. High quality.
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.
