Description:

The Stonk Box is our second Automatic Thermally Bias fuzz pedal, so after plugging it into power (9vdc only), it will take 2-3 minutes on average to sound correct. The color of the LED indicator light might change. Don’t turn the internal trimmer. THAT’S IT. Read on if you would like to...there’s some good stuff.

SUMMARY:

Like the Germanium Fuzz before it, the Stonk Box attempts to take a classic 1960’s fuzz design, and bring the sound into the modern world without bringing any along the flaws and inconsistencies of the original. In this case, we set our eyes on the MK1 fuzz (which is itself a modified version of the very first fuzz ever). We kept the original controls (FILTER and VOLUME), and added a TONE control and a TRIM control to expand the palette of sounds available. Buffer and pedal order friendly (but with no pickup simulation, we had to tweak the output circuit this time). The original circuit is considered one of the hardest of the classic fuzzes to get right because of the difficulty in transistor selec- tion...with our patented technology we can do it easily and consistently...for the first time ever!

AUTOMATIC THERMAL BIAS TECHNOLOGY:

The bias of the transistors in this pedal is automatically regulated by a circuit that GENTLY warms the Germanium transistors (2N404 OR 2N527) to a preset operating point using analog components, and ensures a consistent sound, no matter the external temperature. When the LED is amber, the transistors are warming up to increase their hFE (transistor gain) and to shift the bias point to the correct voltage. When the LED turns green, the warmer is off because the correct bias and hFE have been set. Expect the LED to toggle back and forth every so often while the pedal is on...that is how you know its working. The heaters will warm the transistors enough to still be effective on a summer stage, but far cooler than anything that would harm the transistors. This pedal is designed to operate between freezing and 100F but might still sound fine outside this range....up to about 120F where we’ve found germanium straight up ceases to function...which can happen if it’s left in the sun.

CONTROLS:

TRIM is a gain control right before the two amplifying germanium transistors...turned all the way up is how the stock design is all the time.

FILTER manipulates both the gain and the bias point of the first gain stage. When turned down it will take away gain, bass frequency response, and will bring in to a gentle dynamic expander type effect (where quiet notes will be quieter than normal, the opposite of a compressor) TRIM and FILTER are interactive and there are many different flavors of fuzz and distortion to dial in. This pedal will not clean all the way up, even at low trim volumes there will be some distortion (in a nice way).

TONE is a low pass filter at the end of the circuit, carefully designed to act almost like a tilt EQ to balance the bright attack and full body of the sound, made possible by the original circuit being WAY brighter than the bypassed guitar signal...we think we’ve struck a good balance here.

VOLUME is the output level...which we’ve increased many orders of magnitude from the original. We took the training wheels off so you can push the front end of your amp into sonic madness (if you want). NOTE: this user-beware approch can also lead to settings with a high noise floor. Please remember, this is a crazy and primitive fuzz at its heart...not a piece of pristine recording equipment. Let’s just say there were good reasons for the next four historic revisions of this particular product. If you are concerning people with a high level of hiss and noise, that’s a feature not a bug. It’s fuzz.

INTERNAL TRIMMER
Please don’t turn the internal trimmer. It is precisely set at our factory. Turning the trimmer voids the warranty. The correct trimmer position is marked in case you get one used where a tone lord hath already turnt it.

POWER SUPPLY
This pedal is for use only with a 9vdc Boss syle center negative power supply...There is no battery. Please do not subject this pedal to more than 9vdc or the pedal or power supply could be destroyed. This pedal draws less than 100ma when the heater is engaged, and far less than that when it is off. It will pull those 100ma instantaneously, which most power supplies have no issue with. With substandard or non standard power supplies it is possible the pedal will start oscillat- ing madly at the heater threshhold, where the LED changes, in which case may we suggest using a current doubler cable, or switching to a higher rated power output.

very ergonomic
Color: Deep Black, Color: Deep Black
I bought this as a replacement for one of those gaming chairs that kills your back with a little lumbar pillow and this one is muuuuch better. the back support is everything you’d need and got rid of my neck pain after long periods of sitting and the seat cushion is supportive but still comfortable. It’s the kind of chair that you don’t really think about much because it’s so natural to sit in that you forget it’s there. The armrests flipping is a really nice feature too. One star off only because the head rest is so far back that i can’t really rest my head on it and every part of the chair that’s cloth is made of the same mesh texture like the armrests and seat. but i have no other complaints this is a good chair

Comfortable Ergonomic Chair for Long Workdays
Color: Black, Color: Black
I’ve been using this chair for my home office, and it’s been a great addition to my workspace. The seat cushion is thick and comfortable, even after several hours of sitting, and the mesh back keeps good airflow throughout the day. I especially like the adjustable headrest, which provides extra neck support when leaning back during breaks. Assembly was straightforward, the chair feels sturdy, and the wheels roll smoothly on my floor. The all-black design also gives it a professional look that fits well in any office setup. Overall, it’s a comfortable and affordable ergonomic chair that offers excellent value for the price.

Sturdy but uncomfortable
Color: Black
The seat itself is sturdy and easy to put together, I’ve now had the product for 8 months and had no issues wear/tear despite nearly daily use, but… it’s not comfy, at all. The seat cushion has a texture to it that scrapes at my legs if I don’t have an extra pillow on it or am wearing shorts. Additionally, the seat pillow is just kind of hard. It doesn’t give very much at all, so if I sit on it for more than an hour or two at a time my butt starts to get really sore. It works as a budget option, but invest in a good seat pillow if you plan to sit in it for any length of time.

A chair that does the job
Color: Black, Color: Black
I’m really happy with this chair overall. I wanted something comfortable, sturdy, breathable, and spacious enough for long hours at my desk when I work from home, and this chair delivered. I’d easily give this chair five stars because it exceeded my expectations in comfort, quality, and overall value. Comfort and Support The mesh back keeps it cool and comfortable during extended use. One of my favorite features is the adjustable lumbar support. You can manually position it exactly where your lower back needs support, and it fits the curve of my back perfectly. It provides great support without feeling too firm or uncomfortable. Build Quality and Design The chair itself feels solid and well-built. It doesn’t creak or make noise when shifting around, which makes it feel stable and high-quality. The seat is roomy and comfortable, and the overall design looks clean and modern. Easy Assembly It also came with an instruction manual that was extremely simple to follow, and assembly was very easy. I was able to put the chair together by myself in about 20 minutes without any help. Armrest Functionality I also like the armrests. They aren’t adjustable by height, but they do flip all the way up, which is surprisingly convenient. You can easily slide the chair under a desk or use it as an armless chair when needed. Packaging and Presentation Another thing worth mentioning is the packaging. Everything arrived extremely well-packed. Every individual part of the chair was wrapped securely, including bubble wrap protection for the components. The hardware and accessories were neatly organized, and the chair even came with the necessary tools for assembly in case you don’t own a drill or tool set. The presentation and packaging were excellent and showed real attention to detail. Overall Impression Overall, this is a fantastic office chair for the price: comfortable, supportive, sturdy, easy to assemble, and packaged exceptionally well. I’d absolutely recommend it and would confidently give it a five-star rating.

Nice chair
Easy to assemble and looks clean in my home office. The lumbar support is actually helpful, and I like that the arms flip up so I can tuck it under my desk. It’s comfortable for a full workday, though the seat could be a bit softer. Overall, solid value for the price.
