Arguably, the best OD/Distortion/Fuzz ever! So many usable tones here and it works well with either single coils or humbuckers.





MAS MALO FUZZ REVIEW 7-21-2017 I've been waiting for this for 8 weeks now. I found one at Sam Ash this morning by chance. I left call back notification at numerous music stores nationwide to let me know when it arrives and zilch. Nobody emailed or called. So I bought it, them excitedly put it into two separate pedal board rigs and it is marvelous. I am an international performer, composer, engineer, mixer, and Jazz teacher. It is marvelous. Three basic tonalities with sub-isms within each as you slowly turn the knobs. Crunch, to Liquid Lead, to Full Triple Mas Malo Silicone Diode fuzz. It is truly Mas Malo and lovely. I play jazz and fusion and this is the most tasteful OD/DIST/FUZZ I have ever used. I have owned every Fulltone, Dunlop/MXR fuzz, and every RAT pedal, and every other 70s-90s OD/DIST s a session musician back in the day and this is the smoothest most elegant of all for me. I have a Fultone-centric MAIN pedal board with an original FD2 for the early Carlton genre, a 2 y/o FD3 for more modern fusion tonalities, with two OD pedals slamming into both of them. The Mas sits at the front, followed by a Noebels OD1 into the FD2 then FD3. From there to a dry Plexi 50 watt 2x12 center, and ABY to the wet side into two rear input Randall 1x12 75 watt clean amps for wet L/R. Two comps - A Boss before Mas, and a Keeley 2-knob comp post FD3. On the wet side, a Digi detuner pedal, a stereo Dunlop 18vdc Chorus, a TCE Arena Reverb set to LexiVerb all the time on, and dual Vox Delay Labs -- one pre reverb @116 - 131 ms and the other post Reverb @ 224-300 ms one patch for each of the 10 delay types for both units. The Nobels gives me a very sweet country Deluxe Reverb drive slamming into the FD2 or FD3 for Country-Rockabilly-Country Blues/Hard Rock Shows, and the Mas Malo for that fat wonderful liquid drive that is nicer than any BK Butler tube drive could ever become slamming the FD2 or FD3 for classic to modern fusion. I am very happy. It is even worth buy

Warranty does not cover any damage done to equipment that has been connected to Fulltone's products. Fulltone determines what constitutes "normal use" and also makes the determination as to whether the claim is "Warranty covered,"not the Dealer or the customer. Fulltone Musical Products Inc. is not responsible for and injuries and/or damages related to the use of their products.

FPS-2 (9VDC, + center) does not carry a warranty and will not have a warranty replacement.

Tape Carts (ETC-1 & ETC-2) 3 months: Limited Warranty: Fulltone guarantees the ETC-1 & ETC-2 tape cart to run for 3 months from date of installation only under the following conditions:
1) proof the cart was properly installed on a clean, well-maintained Fulltone TTE or SSTE by making a clear, close-up video of the Tape cart running after the install. Keep this video on file in case of any problems. This video will help us diagnose any other problems as well.
2) The cart must not have been damaged due to user-error. We will make the determination as to what constitutes "user-error."

Batteries: are not Warranty-covered.

Tubes: 3 months

Customer Troubleshooting: Warranty support is entirely dependent on the Customer's willingness to assist in troubleshooting. The customer agrees to furnish a clear video (cellphone video ok) representing the problem at hand, and we have provisions on our website to upload such videos. Refusal to submit such help or a video will result in instant disqualification for repair assistance. 90+% of "My pedal is broken... I want a new one NOW" emails result in the discovery that the item was either plugged in backwards, dead battery, the wrong power supply was used, another pedal in the customer's chain is actually the culprit, or the customer doesn't understand how to operate the device and how it's supposed to sound.

Shipping: Customer is responsible for all shipping costs unless there are extraordinary circumstances and Fulltone decides otherwise. This decision is made only by Fulltone, not the Dealer or Customer. There are no shop visits or drop-offs unless cleared & scheduled in advance. All items must be shipped to Fulltone via FedEx, UPS, US Mail, & DHL. We strongly recommend the customer follow the companies' packing guidelines to assure that they have recourse should the item become damaged during shipment. Fulltone is not responsible for any lost or damaged items during before, during, or after the shipping process.
