DESCRIPTION

This little unit can be used in front of other pedals, separately, however you please. The Darkglass Harmonic Booster both boosts and enhances whatever signal you give it, without giving it too much color. It is a full preamp, so you can dial in the treble, bass and mids as you please…but additionally allows a player to select the mid frequency of their choosing (between 250Hz and 2.5kHz).

Players remark that their tone gains additional clarity and spark when adding this to their arsenal.

From Darkglass:
Designed to be the perfect complement to the Darkglass distortion circuits, the flexibility and portability of the Harmonic Booster is also the perfect one-stop solution for gigging musicians in search of a precise and harmonically rich clean preamplifier.

**Sorry international bassists, but US Dealers are not authorized to ship Darkglass pedals outside of the US. Please contact us if you are having trouble finding Darkglass products in your home country.

Kinda of a cool gadget
Color: Cool White
I really didn't know I needed this until I got it! Easy and quick to recharge batteries (they do not come with rechargeable batteries). Put out enough light for an evening outside around the table

Love the Warm Glow!
Color: Warm White
This light is very easy to install and has 3 different lighting options. I love the warm white light it emits as opposed to a bright white light that could attract bugs at night. Perfect light for patio, deck, camping, golf cart, etc!

It feels cheap and works just okay
This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!
Color: Cool White
This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.

A lovely gentle cleanser - good for rosacea-prone skin
I have also purchased the Thayer's Milky toner and really liked it. I normally use oil-based cleansers, like Beauty of Joseon ginseng oil cleanser (which I still do love), and Cosrx makes a snail mucin cleanser that I use for cleansing off makeup or sunscreen and it's very nice. But for my daily regular wash, particularly in the morning, I like a very gentle easy-to-wash-off cleanser that hydrates and soothes. This Thayer's has no perfumes/fragrances! Good for rosacea-prone skin. Hydrates and soothes very well. It didn't strip my skin, wasn't oily at all (though good oil-based cleansers do feel oily they don't stay oily), and felt wonderful as I cleansed my skin - also washed away very easily and quickly; I do about 14 or so splashes of water to be sure all is removed then use a washable reusable toner pad with toner to remove any lingering residue. It doesn't make my skin feel tight or dry. It is gentle. It doesn't lather up, which I like since I don't use lathering products or soaps on my face. No burning, itching, redness, or any irritation at all. I normally use K-Beauty but Thayer's is one brand I will use that's not in the K-Beauty products category. It really is a lovely cleanser.
