This pedal is truly for fuzz lovers, with a huge dynamic range, offering versatility, control and power, A LOT OF POWER. With a robust low end that never compromises you high end crisp, the Stone Blender is perfect for guitarists, bassists and synth players alike. We based the circuit on the 1990's Sola Sound Tone Bender and created four distinct fuzz sounds ranging from classic to modern, wild to tame, each dynamically shapeable using the Tone, Fuzz, Vol and De Clip controls.

Fuzz #1 (1N60) -  Mogwai turns into a furry little biting gremlin with this purry overdrive-like fuzz, offering volume boost and added crunch

Fuzz #2 (1N4148) -  Sizzling up top while punching you in the gut, this is the 1990’s Sola Sound Tone Bender. At this setting you get the classic all time favorite Tone Bender Fuzz. 

Fuzz #3 (Yellow LED) - Take a walk on your wild side. This animal is loud, aggressive and likes like to snap at its prey before devouring it up.

Fuzz #4 (Blue LED) - Planets collide with this out of control extraterrestrial beast. Extremely distorted and high gain, this is full blown madness in your face and yes, it goes to eleven.


Volume - You know what this is

Fuzz - Controls the amount of signal going into the fuzz circuit. Counterclockwise for less fuzz, clockwise for more fuzz

Tone - Filters high & low frequency (Counterclockwise for low, clockwise for high)

De-Clip - Offers further tonality shaping in the mid range, controlling how “forward” the guitar sits in the mix, thus adding presence. Perfect for bass players and guitarists who want to stand out.

Return Policy:

All Red Noise Pedals come with a 14 day money back guarantee as long as pedals are returned in their original new condition and are in perfect working order.

At Fuzz Audio, all vintage/NOS vacuum tubes purchased through our website are guaranteed for one year from purchase date. We accept returns for tubes going noisy, losing output/performance prematurely, and of course losing function all together.  (Read about power tubes below). 

We will not cover damage from red plating neglect, glass breakage of any kind, loose bases, or other obvious faults that are due to neglect, rough handling or egregious constant use. 

This policy is meant to protect the buyer from having a tube go out on them prematurely from a flaw we missed. Tubes, especially preamp tubes, should last half a lifetime, and well beyond a year, so we want to guarantee each customer that you get a tube that will last.

For power tubes, although we will honor any faults mentioned above, we will not accept a return for a power tube that has obviously been used for 6+ hours a day for every day of the year for one year. Power tubes that have clearly been used beyond their normal wear point will not be accepted. 

If you suspect one of your vintage Fuzz Audio tubes has gone bad within one year of purchasing, simply reach out via our chat or at and we will assist you in the warranty exchange process. No receipt is needed.

Please note, it is possible we will be out of stock of the tube that is in need of a swap. If this is the case, we will either offer a refund, credit, different tube, or send the first available tube of that type when it comes back in stock. 

If you have any questions or concerns, please reach out!
