The Kz TREBLE BOOSTER is a simple booster pedal that descends from the Rangemaster that was born in England in the 1960s.
Unlike the full-range clean booster, it is designed to strongly boost the high-midrange, so it maintains a tight bottom end even at max level.
Just plug your guitar into his Kz TREBLE BOOSTER and feed the boosted signal into a crunchy amp for some old school distortion.
If you turn the guitar volume down to about half, it will change to a bright clean sound.
・LEVEL
The "LEVEL" knob located in front of the pedal adjusts the output level of the boosted signal.
・TONE
The "TONE" toggle switch on the output side allows you to switch the tone of the output.
When the knob is up, the tone is gorgeous and edgy, and when the knob is down, the tone is mild and warm.
・RANGE
The "RANGE" toggle switch on the input side can switch the input range.
Turning the knob up produces a low-cut, tight tone, and turning the knob down produces a fatter tone.

A very good option if manual grinders are problematic
Color: Black/Black
These work well, though I haven’t had them long enough to vouch for charge duration.
They are well thought out devices, with an actual light shining from the bottom to help gauge the amount of salt and pepper, even in lo light. :D
I haven’t not altered the grind size, so I can’t speak to that either. Grind speed is as good as many hand grinders, so it’s a delight specifically when grinding a lot (salt for Margarita glass edges!).
The price was good, and meets my expectations.

Value & Quality
Color: Black/Black
Just like described works excellent. You cannot beat it for the Money 4.8 should be five stars. Adjustable coarseness is real nice too. I do a lot of barbecuing and you want a thick pepper and salt for brisket. Just real nice one Hand operation if you’re doing something so it was a salt shaker pepper shaker but this one being able to grind fresh is real nice.

Sleek, Easy to Use, and Works Perfectly!
Color: Upgrade Silver, Size: Rechargeable
I absolutely love this electric salt and pepper grinder set! The stainless steel design looks modern and elegant on my kitchen counter. They’re super easy to use — just press the button, and you get a consistent grind every time. The adjustable coarseness feature works great for everything from fine salt to coarse pepper. The built-in light is a nice touch when seasoning food at the table or over the stove. Battery life is good, and refilling is simple. Excellent value and quality — highly recommend!

Nice salt and pepper grinder set!
Color: Upgrade Silver, Size: Rechargeable
These are very nice quality. They work really well. You can adjust the coarseness as you prefer. They aren't overly loud. I got them for someone as a gift for someone and I'm going to get myself a set also because I really like them. They charge quickly. Overall, a really nice set that seems like it will last a long time.
