From the manufacturer:

Zoar®
Dynamic Audio Grinder

Zoar is a medium-high gain discrete distortion (using only transistors; no opamps or diodes in here!) that has that touch sensitive amp-like quality to it that everyone craves. It has been finely tuned to create a highly tweakable hi-fi and modern sounding distortion, but with the ghosts of old school circuitry to deliver a grind that is both instantly familiar and delightfully unique. Want that defined sparkle and tightness of an overdrive? This has it. Want that low-medium gain fuzz that’s perfect for drop tuned guitars and basses? This has it. Want to be able to dial in and control every nuance of your tone from jangly on-the-verge of break up to blowing the walls out heavy saturation? Then this is the pedal for you.

Customize Your Sound

This meticulously crafted box has six knobs that allow you to truly customize your sound with the Level, Weight, Gain, Bass, Middle, and Treble controls. The red LED light indicates when the distortion is activated by the Flexi-Switch® enabled footswitch.

The Gain control on Zoar goes from the edge of break up all the way over the cliff into the crunchy, grinding abyss. The character of the distortion is heavily dependent on the setting of the Weight control as well as your guitar’s pickup type, and it is further fine-tuned by the EQ section.

Touch-Sensitive Controls

While having its roots in a very familiar past, the passive 3-band EQ has been finely tuned for modern tones. While this style of tone shaping seems simple on the surface, it is deceptively complex and highly interactive.

The 3-band EQ and Gain controls give you nearly unlimited options with great focus and sensitive precision, but the real powerhouse of Zoar is the Weight control. This control dictates the amount of low end that is passed into the circuit, thus controlling the entire character of the pedal. From a mere clean boost to a high gain distortion to overdrive to the crispy Hi-Fi fuzz territory, this function gives you everything.

The Level control hits unity gain around noon, but this is dependent on where the other controls are set. In addition to controlling the output volume, it also plays a small part in the controlling the voice of Zoar. By adjusting the Levelcontrol with any combination of EQ (boosting the frequency bands and cutting the output volume), you can achieve drastically different curves that have the feel of the more traditional low pass filter type tone control.

Frequency Response

Running Zoar at 18v

Want to elevate your sonic spirit to a higher level? Try running Zoar at higher voltage! Zoar can handle power up to 18v DC. Higher voltages will yield a different frequency response with more defined dynamics and a faster response. When powered at 18v, the range of clean tones are widened, dirty tones become punchier with better note articulation, low frequencies are tightened, the Treblecontrol will cover a broader spectrum without becoming harsh and the output volume nearly doubles! The experience is not unlike plugging into a wall of high wattage tube amplifiers!

Controls:

Level: Adjusts the output volume.

Weight: This is an input frequency control that changes the voice and saturation of the distortion. Turning Weight clockwise allows more low frequencies to pass through. This increases the gain, allows lower frequencies to clip faster and can shift the tone of the pedal from tight distortion to a loose fuzz.

Gain: Turn clockwise to increase distortion. This adjusts the transistor bias. A little static sound when turning is completely normal.

Bass: Passive bass control, adjusts the low frequency content between 0 and 800Hz +/- 15dB.

Middle: Passive middle control, adjusts the midrange frequency content between 500Hz and 3kHz +/- 10dB.

Treble: Passive treble control, adjusts the high frequency content between 1kHz and 10kHz +/-15dB.

Tech Specs:

Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs


Current Draw: 10 mA


Input Impedance: 1 MΩ


Output Impedance: <10 kΩ

Flexi-Switch® Technology

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

  • For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.

  • For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Ledges is buffered bypass with tails. Power is required to pass signal.


Power

This device takes a 9-18 volt DC power supply with a standard 2.1mm negative center barrel plug. We recommend using a pedal-specific, transformer-isolated, wall-wart power supply or a power supply with multiple isolated-outputs. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not always filter dirty power and may result in unwanted noise. DO NOT POWER THE ZOAR HIGHER THAN 18V!

Works For Desired Use
Color: Black, Size: 4 Panel-136‘’W-Round Pad
I recently purchased the Room Divider 6FT Folding Privacy Screens, 4 Panel Partition Room Dividers, and I must say, it has transformed the way I use my living space. The four-panel design is both elegant and functional, providing instant privacy without feeling bulky or overwhelming in my room. Setting it up was a breeze; the folding mechanism is smooth, allowing me to adjust the configuration as needed—straight, angled, or zigzag. I particularly appreciate the sturdy build; the panels feel solid yet lightweight, making it easy to move around when I want to reconfigure my space. Aesthetically, it’s a great addition. The neutral finish blends well with my décor, and the simple design doesn’t draw too much attention while still offering a sense of separation. It’s perfect for creating a temporary office corner, dividing a studio apartment, or even using it as a backdrop for online meetings. If I had to point out a minor downside, it would be that the divider isn’t completely soundproof—so conversations can still carry through—but for visual privacy and space management, it’s excellent. Overall, I’m extremely satisfied and would recommend it to anyone looking for a versatile and stylish room divider.

True to size & Use a Drill
Color: Beige, Size: 3 Panel-102‘’-Round Pad, Color: Beige, Size: 3 Panel-102‘’-Round Pad
Love this! Works perfectly for where I wanted it. I did measure my room incorrectly and thought it would be smaller, thankfully it’s not and thankfully it’s not bigger than the room itself. I did like how the whole thing was move-able but it was a bit annoying so I just added extra clips to the left of the middle one and unscrewed the right of the middle at the bottom so it opens like a door, this did make it a bit flimsy but duck taping it to the wall as anchor it works. 100% recommend, but do suggest a drill and a second set of hands to put it together, due to its size it can be a bit difficult to maneuver putting together yourself. Also if you have a clingy cat like I do, and think this will help keep them out, no, my cat who is very large can manage to squeeze underneath it.

waste of money
Color: Black, Size: 4 Panel-136‘’W-Round Pad
This is a total waste of money. Its only going to free stand if you arent moving it. If you are planning on dividing a room, and then folding these for space and then dividing the room again, itll last a few days. The poles kept coming off of the screws that holds the fabric on the poles together. Was fixing this EVERY DAY. Finally got tired of doing this and just threw it out. Lot of money spent on garbage. Get a sheet room divider, or something that isnt cheaply made. Was simply making an office type space in a bedroom, to seperate the two areas for work, and folding it kept making the poles come off those twisted screws. just not worth it.

Absolutely love this room divider!
Color: Beige, Size: 3 Panel-102‘’-Round Pad, Color: Beige, Size: 3 Panel-102‘’-Round Pad
When they say you can't see anything through it, they are correct. As you can see by the video, the cars are traveling by with the sunlight on the divider and you still can't see any cars passing nor can you see the ones in the parking lot. You can also tell it blocks out the sunlight too which is a definite plus for our store. Quality material on the divider. Material is nice and snug on the poles with no ripples. I also like the base of these, they make the divider nice and sturdy and can be adjusted if floor is uneven. Also the design of the legs allow them to go under your furniture. Also putting them together is pretty easy. Just make sure you when you are putting the poles together to make sure at the top of the pole that the indent screw hole faces out. This makes for a better look. The directions don't say which way to turn and at 1st, I had one, one way and the other was another way as both ways work that way but I wanted a uniform/better look.
