Description:

 The Colorsound Power Boost was one of the first overdrive circuits to hit the pedal market. Originally created around 1968 by Gary Hurst, it offered players a wide range of useable guitar sounds with its simple 3 transistor pre-amp design and 2 band Baxandall EQ.  The first units ran on 18 volts offering a more open and dynamic tone than the later models, which ran at 9.  The BLAMMO! Voltage Booster recreates that classic Power Boost circuit using original BC184L transistors but offers both 9 AND 18 volt options by adding an internal charge pump on a toggle switch that doubles the operating voltage internally.

 

Pretty neat, huh!? Well, there’s more.

 

 We also added a relay based true bypass switching system to quiet that annoying click / pop standard 3PDT footswitches make when pressing them. Plus they’re rated for 3x as many cycles. We also beef up the power filtering and add a polarity protection diode to defend against any potential damage an incorrect power supply might cause if accidentally plugged in. The master volume control mod allows proper overdrive and distortion sounds at lower bedroom levels, which was one of the drawbacks original units had. We then redesigned the PCB to fit into a more compact pedalboard friendly enclosure with board controls (pots and toggle switch) and a screen printed 2 color graphic based on the original.

    Keeps beard soft and smelling amazing
    Scent: Majestic Oud, Size: 1 Fl Oz (Pack of 1), Scent: Majestic Oud, Size: 1 Fl Oz (Pack of 1)
    My husband has been using this beard oil for a few weeks, and we’re both impressed. It absorbs quickly without leaving a greasy feeling and makes his beard noticeably softer and easier to manage. The scent is warm and rich — not overpowering — and lasts throughout the day, which he really likes. It also seems to help with dry patches and keeps the skin underneath feeling hydrated. Application is easy, just a few drops in the palms and rub through the beard. Overall, it’s become a part of his daily routine, and he’s happy with how smooth and healthy his beard looks.

    Expected a better smell
    Scent: Sweet Tobacco, Size: 1 Fl Oz (Pack of 1)
    I picked up the Sweet Tobacco scent and was honestly expecting something a little richer and smoother. The smell isn’t terrible, but it’s not good either, and it’s definitely not what I had in mind. It comes across a bit more artificial and lighter than a true “sweet tobacco” scent. As far as performance goes, the oil itself does its job. It softens my beard and keeps it manageable without feeling greasy, which I appreciate. I just wish the scent matched the quality of how it works. Overall, it’s decent if you’re just looking for a basic beard oil, but if scent is a big factor for you, this one might be a bit disappointing.

    Quality Sandalwood scent, just not the same formula as before
    Scent: Sandalwood, Size: 1 Fl Oz (Pack of 1)
    I love the quality of sandalwood in this product, it smells terrific. It’s also potent and projects to where people around you can smell it on you. Although I love this product, I just recently bought this again and I’m starting to think it’s not the same formula that I got from before. Not as strong. This is better than the Everyman Jack product however and much higher quality sandalwood, I just wish that I can get the same formula from when I first purchased this it was super rich and wanted a full size bottle of this stuff.

    More of a travel kit
    Size: 4 Piece Set
    I love this stuff. Smells great makes my beard soft and my skin not itchy/flaky. The beard Shave loom is by far the best shaving cream loop that i've ever used. These bottles are Really small and would work really well as a travel kit. But Jack black's products are fantastit's . just do it. stop, what are you waiting for.
