PartNumber: 900

Details: The ~900 is a ferocious fuzz pedal featuring two cascading JFET gain stages. The ~900 is a spiritual successor to our discontinued Four Eyes Fuzz, having a similar fuzz circuit. This pedal has a very wide range of gain, brought to you by four interactive controls: INPUT, FUZZ, BIAS, VOLUME. The INPUT section is a 'mu-amp' design. The INPUT knob controls the level going into this first gain stage - you can go from clean with lots of headroom, to completely slammed and distorted - and everything in between. The FUZZ knob controls the level going into the second JFET gain stage. This section is very dependent on the level of the INPUT. The BIAS knob adjusts the bias of the second gain stage. This gives control over the saturation symmetry, and can also allow gating when turned up high enough. The BIAS knob is especially interactive with the FUZZ knob. The VOLUME controls the master volume output. This pedal has a lot of gain to offer and can get quite loud. The ~900 is an overall very versatile fuzz pedal. It stacks well with other pedals and is friendly to all sorts of instruments and signal levels. The INPUT especially will dictate how the pedal responds. At lower INPUT levels, the FUZZ will have a wide range of tones and interact heavily with the BIAS knob. When the INPUT is raised high, the FUZZ and BIAS will be a bit less responsive - but at that point you will be experiencing a thick wall of distortion/fuzz.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.
