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.
SPEC
Size: 48.3(W) x 93.5(L) x 48.0(H)/mm
Weight: 146g
True Bypass Switching
Power Consumption: 9VDC/2mA
Accessories: 9V battery plug, rubber feet, manual, warranty card
*Designed exclusively for external DC9V power supply. Power adapter not included. Please use a stabilized one such as the BOSS PSA series. Also, a battery can be used, but it cannot be stored inside. An external 9V battery plug is included instead.
* Supplying power from a power supply with multiple outputs may cause power source noise. It is recommended to use a power supply capable of isolated output.
*Please note that connecting DC15V or DC18V may cause malfunction (mainly LED). Any damage caused by driving with a voltage other than 9V is not covered by the warranty. In addition, Kz TREBLE BOOSTER is designed to produce an appropriate tone with a 9V power supply.
*There is a change in the notation on the front panel from production in February 2022. (IN, OUT, TONE, RANGE notation changed from horizontal to vertical, EDGE/WARM notation added to TONE mini switch, TIGHT/FAT notation added to RANGE mini switch)
*From March 2022, the LED has been changed to blue in order to stabilize the supply of parts.

Very nice winter shirt.
Fit Type: Slim Fit, Color: Blue, Size: Large
These shirts are beyond what I expected. They’re thicker than I thought but not being too heavy. They wear well and they also wash up very well in permanent press and I dry them on permanent press also. No problem with wrinkles. I just take them out of the dryer and hang them up and they look great.

Amazon Essentials Mens shirt review - Good shirt, great value.
Fit Type: Slim Fit, Color: Grey, Size: X-Large
First, this is Oxford. This is a tough fabric that looks a little like pinpoint and feels a little like flannel. That is, it does not have the sheen of a dress shirt and is not as thick and soft as flannel. It hits a nice spot in between. The fabric is soft enough and thick enough to wear casually in the heat of summer. (It is cooler than a very thin and very cheap shirt due to it's absorbancy.) The fabric appears and feels to be quality.
The cut is good for me. It is tailored enough to look good tucked in and roomy enough for work and play.
The seams are doubled and good quality. I did not find mid seam knots, broken threads, etc. Seams are likely very durable.
The Goodthreads shirt is a little more expensive. It is a little thicker and softer. It is almost a flannel. However, the thickness and softness caused it to shrink more in the dryer. It loosened OK as I wore it, but I think after multiple washings and dryings, the Goodthreads may get a little tight. I have no concerns with the Essentials.
Good shirt.

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good
