Demo board unit - Your Face 60s in YELLOW and equipped with External Bias and Hybrid transistor mods from the Wren and Cuff Custom Shop. First photo is the actual photo for sale, the rest are stock.

About the mod:

Bias mod: This mod adds a bias knob that allows you to adjust how the fuzz sounds. It's a hard one to describe in text, but it will let you go from a sputtery, "wrong" weird sound, to a buttery smooth proper Fuzz Face® style sound (and everything in between).

Hybrid transistor option: This mod puts a germanium transistor in the first position, a silicon transistor in the second position. Gets a sweet mix of modern with the smoothness of a germanium. Also makes the bias a bit more stable than an all germanium setup.

—See regular description below—

Germanium transistor lovers, rejoice! We've done everything possible to make an amazing vintage pedal, even better.

Dripping with fuzz, super dynamic, trim-pot adjustable bias, and more. I love this pedal and I think you will too.

Don't like the low output on a traditional FF? Fixed it. All the volume you could ever want or need.

Don't like the way that a traditional FF fuzz knob is only useful at the last end of the knob? We've added a reverse-log potentiometer that widens that range and let's you dial things in just right.

Mullard “tropical fish” out-cap with increased value to allow more lows to come through. Also, Mullard tropical fish caps just look damn cool.

Custom “You” knob functions as a low-cut to reduce some of the low-end squash, letting you dial things in just right for "you". This is a simple but fantastic mod that gives an incredible amount of versatility. I've seen this mod alone turn FF haters into instant fans.

If you've poured over the masses of FF descriptions trying to decide what to get, you can't go wrong the the Your Face 60's.
