Say "hello" to the 1979! An evolution of the now discontinued Mojo Hand FX 1978, the 1979 is based on the notoriously high gain Big Muffs that were manufactured during the late 70s. Favored by many players for it’s outrageous grungy distortion (most notably Billy Corgan), it features op-amps instead of the traditional transistors found in every other Big Muff variant.

The 1979 features a footswitch to bypass the tone knob, so you get ALL the bass, ALL the treble, and a HUGE helping of extra mids and volume. Perfect for slamming your amp into a ripping solo, or doom/stoner mode. But most importantly, the tone bypass has it’s own volume knob so you can set it to unity or boost! We also adjusted the taper of the original gain pot to have a more usable sweep.

This peculiar Muff uses an IC, instead of the traditional transistor set, resulting in something that’s both familiar and different at the same time. The sound is more raw and aggressive than a typical BMP. Please do not expect subtlety. This pedal does not “clean up well” with your volume knob. It doesn’t sound pretty. It’s probably not appropriate for waltzes or jazz standards. It’s not supposed to be. It smashes you in the face.

Enjoy.

Like all Mojo Hand FX products, this pedal is housed in a sturdy, die-cast aluminum enclosure with professional powder coating and printing.

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!

Bonita pero pueden mejorar ciertas cosas
Size: One Size, Color: Black/Silver
La compré hace dos meses y la e usado muy pocas veces de lo que me gustaría el color es bonito el diseño es precioso, la cadena se siente de buena calidad pero a pesar de que tiene poco que la tengo y que casi no la uso ya se empezó a despegar la “costura” (no sé el nombre correcto) de donde se dobla para cerrársela!

Great option for a great price
Size: 7.5, Color: Black
I love these sandals. They are well made, true to size and soft suede. They are lightweight and feel just like my UGG goldenstar sandals. (These are not as adjustable, so if you have narrow or wide feet, these may not be for you) These a great value for the money, especially for medium width feet. The strap across the toe is not adjustable, but fit my feet just fine. The ankle strap was a good length for me. And the Velcro is strong. These sandals are a great value for the money. I will probably start looking into kookaburra before I rush to buy the more expensive ones now.
