The Deluxe Bass Big Muff Pi from Electro-Harmonix is a distortion/sustainer pedal which creates large sounding and versatile bass distortion. This pedal features seven knobs. The Volume knob works as a master volume for the entire pedal and is capable of boosting the input signal by 14 dB above unity gain, and obtains the right balance between bypass and effect. The Blend knob mixes between the dry and distorted signals. The Tone knob provides a range of sounds from high treble to deep bass on the distorted effect only.

The Sustain knob adjusts the amount of sustain and distortion. The Gate knob controls the input amplitude needed to open the noise gate, and removes unwanted hum. The HPF knob adjusts the cutoff frequency range of the high pass filter from 125 Hz to 1.75 kHz. And the LPF knob adjusts the cutoff frequency range of the low pass filter from 60 Hz to 10 kHz. The Deluxe Bass Big Muff also includes an Input toggle switch and Crossover and Bypass footswitches. This pedal has a DI output to connect directly to mixing consoles and recording equipment.

Holy grail for type 1 rosacea
Size: 1 Ounce (Pack of 1), Size: 1 Ounce (Pack of 1)
This has saved my face. I have type 1 rosacea and my skin has been pissed off for the last eight months straight. I have tried everything including compounded prescription creams that only made my face flare worse. I deal with a lot of flushing and burning that can be triggered by the slightest bit in temperature rise or just seemingly at random, especially at night. Since using this product my skin has calmed down drastically. It's only been a couple days, but so far I'm thinking this is a holy grail product for me. I also purchased the Glenser because the oil cleanser that I was using had fragrance and alcohol, which can be extremely irritating for rosacea. Since switching to Prequel I can honestly say my skin is so much happier and less reactive. Worth a shot if your a rosy girl like me.

A perfect edition to my Rosacea skincare routine
Size: 1 Ounce (Pack of 1)
Unfortunately, this doesn't fully get rid of the optical redness from my Rosacea, probably only about 30-40%. However, after using it consistently,(I'm now on my 2nd bottle, using at least twice a day), I have noticed that my skin is softer, less textured and definitely less red overall. My face gets super red especially towards the evening, but waking up in the morning I have noticed less and less redness. It kinda tingle/burns on my most sensitive areas where there's obvious inflammation, but the sensation fades as it totally absorbs into my skin. I wear it as a 2nd layer to my routine, and it wears well under makeup, just remember to moisturize after applying it, and before adding any makeup. It does also tend to pill up if you accidentally touch/rub on your face, so just be mindful of that. I am very satisfied with this serum and even gifted a bottle to my Mom. As a Rosacea Girly, I love this product and have permanently added it to my skincare routine.

Surprisingly effective
Size: 1 Ounce (Pack of 1)
I frequently have combo skin with oily, dilated pores on my nose and dryness in other areas. I got this to address blotchy redness (my skin can be especially reactive to too much moisturizer and/or too many actives). Redness Reform definitely helps to calm the redness, but I've been really surprised to see it also calming down my dilated pores and making my skin overall much more balanced. With consistent twice daily application, I find I'm able to step up my use of retinoids and AHAs without seeing increased irritation. It's been so helpful for multiple concerns that I've already repurchased to make sure I have a new bottle on hand when this one runs out! Giving 4 stars because I wish there were more product for the price. You can definitely get away with 2 small pumps to cover the face and neck if your skin is moist/hydrated after cleansing, but I find I'm liking to use just a bit more (4 pumps or so) to get really thorough coverage and hone in on the areas that need it most. The other reason it isn't 5/5 for me is because it's too thin to actually deliver on the promise of optical correction. Yes, it's green, but it's doing very, very little short-term to camouflage redness. I do like the consistency, because it does allow a little to go a long way and gives it a higher-end application feel, but it's misleading to suggest that you'll get meaningful color correction while using this product.
