hi power pedal Crazy Tube Circuits | HI POWER | Colorsound & Hiwatt Amp in a Box | Dual OverdriveHI POWER is our next endeavour in pedal + amp in a box overdrives inspired by the sonic combination of two British tone machines that helped shape the sound of Pink Floyds Wish You Were Here Album.

HI POWER is our next endeavour in pedal + amp-in-a-box overdrives inspired by the sonic combination of two British tone machines that helped shape the sound of Pink Floyd’s Wish You Were Here Album.

On the right side of the pedal, you will find a recreation of the Colorsound Power Boost featuring the true-to-the-original spec BC184 transistors running on 18V DC (via an internal voltage booster circuit) and the ultra-flexible 2-band Baxandall EQ circuit. We’ve added extra features, like a bypassable master volume control, a reverse-log gain control to ensure better sweep and transition from clean to mean (compared to the original’s linear taper) and a toggle switch the engage the latter higher gain / lower headroom version of the original boost circuit called Overdriver.

On the left side of the HI POWER you will find an all-analog circuit set out to emulate the sound and feel of a Hiwatt amp. Following the path of the famed British tube amplifier our circuit offers authentic amp tone and feel. From the big bold high-headroom clean sounds to the face-melting crunchy tones.

True to the last detail we have included the full EQ section along with a presence control located at the negative feedback of the power amp simulation circuit. A headroom toggle switch selects between the high headroom 100w power section provided by a quartet of EL34s or the lower headroom and compression provided by a 50W power section with a pair of EL34s when hit hard. Similar in operation to the original amp design the master volume control was designed to produce more gain at higher settings.

We’ve taken our design a step further by adding a switch to select between input channels. You can select between the full frequency response of the normal channel of the amplifier, the increased presence and tight low end of the bright channel input or the enhanced frequency response and added gain of those inputs linked together.

Like our other dual overdrive/amp-in-a-box designs we have also included a passive effects loop to give you the option to connect your beloved pedals between your booster/overdrive and amp in a box or use the two sections as separate and independent effects when using an external bypass switcher/looper.

HI POWER also features a power-up bypass/engage pre-set function for the onboard footswitches. That way you can select which state your pedal will go to when you plug the power supply. This function comes in especially handy to people that use remote pedal switchers / loopers as they only set the power-up state of the pedal once and then operate from the controller.

Warning: This unit was designed for 9V DC input only. Do not use a higher voltage power supply.

Convenient and Cost-Effective Air Filter Set for Gasoline Engine
Size: CRV (2023-2025) 1.5L Gas, Size: CRV (2023-2025) 1.5L Gas
Why did you pick this product vs others?: The set includes both the engine air filter and the cabin air filter, which I find extremely convenient because both usually need replacing around the same time—especially if you drive in dusty environments or have seasonal allergies. Ease of installation: I replaced both filters myself in under 20 minutes using just basic tools. No instructions are included, but a quick search online brought up several helpful videos tailored to my car model. Both filters fit perfectly without any force or trimming needed, which isn’t always the case with aftermarket brands. Functionality: From past experience, replacing the engine air filter regularly (every 12,000 to 15,000 miles as suggested in the owner’s manual) helps maintain better fuel efficiency and extends engine life by keeping debris out of the combustion chamber. After swapping in the new filter, I noticed the engine ran slightly smoother—especially on acceleration. Smell: The cabin air filter is equally important, particularly for passengers with allergies or sensitivity to airborne particles. I could immediately tell the airflow from the vents was stronger and fresher-smelling after the replacement, which suggests the old filter was overdue. Value for money: The ITESIER Cabin and Engine Air Filter combo pack is a smart buy for anyone maintaining a gasoline-powered vehicle like my Honda Civic. This combo pack offers good value for money compared to buying each filter separately. Quality: Overall, if you’re comfortable with basic DIY car maintenance, this kit is a great choice. It’s affordable, fits properly, and provides an easy way to knock out two important maintenance tasks in one go. Filter quality: The filters are high quality. They work without problems. Just be aware that this is designed only for gasoline engines—it won’t be compatible with diesel or hybrid powertrains.

Exactly what I needed
Size: CRV (2023-2025) 1.5L Gas
I'm not sure how much there is to say about an automotive cabin air filter. I double-checked the specs to make sure this was compatible with my car, ordered the filter, then installed it. It fit, it didn't have a weird smell, I haven't thought about it since. That's exactly what I want in an air filter. Five stars!

Worked perfect for my Jeep Grand Cherokee L
Pleasantly surprised with the quality. It seemed better than the original filter that I took out of my 2021 Jeep Grand Cherokee L. Seems like it’ll last a while and I really like the charcoal addition. Has worked well so far and car smells clean.

Quality filter
Nice filter, fits perfect in the WL model (not the WK!) I will buy this one again, far superior to the OEM filter from the dealer!
