Bjorn's Description
In the past, boost pedals have been used as "overdrive pedals". Today's modern overdrive pedals actually produce distortion whereas vintage overdrives were designed to distort the amplifier.

One Control RASPBERRY BOOSTER is a unique boost pedal designed to be used like a vintage boost/overdrive. With this pedal, the guitarist has full control of the amount of detail in the gain. Have full control of the distortions texture when boosting your favorite amp or distortion pedal.

Controls
Let's talk about the controls. As you raise the Gain knob, the compression of the boost will increase. At the maximum level, expect a good amount of distortion while maintaining a detailed/clean tone. The Master knob is used for volume cuts as well as an overall volume boost. If a boost pedal increases the output volume and gain by the same amount, the overall volume will increase more than expected, making the ideal amount of distortion difficult to dial in. By adjusting the Gain and Master knobs separately, the RASPBERRY BOOSTER can achieve the desired amount of gain at the desired overall volume.

There's one more control knob, and quite frankly, the most unique one that is left to discuss... The Z knob. This knob controls the input impedance, from 9.8K to 319K. Don't worry, it's not complicated. The Z knob is the most 'musical' of all the controls on the Raspberry.
How does the Z knob impact the sound? Adjusting this knob allows the guitarist to manipulate how the top end of your tone rolls off. If you set it to the minimum, the solid body's single coil becomes soft and warm like a plump semi-acoustic humbucker.

As you increase the impedance, the top end changes sharply and the resolution of the whole tone also changes. It also affects the movement of your tone when you operate the guitar's Volume knob while the gain is being boosted. This will enhance the usability of your guitars' controls.

RASPBERRY BOOSTER can be used in conjunction with various pickups, amplifiers and effects. When you boost a tube amp with the RASPBERRY BOOSTER, you'll understand the true definition of the word "overdrive".

It's important to place the RASPBERRY BOOSTER at the beginning of your pedal chain in order to take advantage of the Z (impedance) control. Impedance can be effected by various factors and we want you to enjoy the endless creative possibilities.

Who cares if its plastic... let's not be silly
Color: A-Silver
Why are people so obsessed with metal housing? Metal literally serves no purpose. It's just a cover. It won't make a better coffee with metal housing nor will it last longer. I personally don't care what it "feels" like to touch it, I don't even notice it. I make coffee with it, it's a tool. I don't touch it to "feel how nice it is". That's just weird. Anyway, what a great machine. To me instant heating is worth all the missing features of fancier machines combined. I've had it for several months now, and I have it dialed in. I make up to 5-6 lattes a day and I've made about a 1000 by now. Still working great. Not interested in upgrading.

Great Budget Espresso Machine That Performs Better Than Others Costing Much More
Color: A-Silver
I’ve been using the Casabrews 5418 Pro for a few months now and it’s been a solid addition to my kitchen. It looks sleek and feels well‑built for the price, and it heats up extremely fast — reaching brewing temperature in just a few seconds thanks to its FlashHeat™ system. The 20‑bar pump and built‑in pressure gauge give you good feedback while pulling shots, and the steam wand produces nicely textured milk for lattes and cappuccinos.  The removable water tank is a nice touch and makes refilling easy. While it’s not perfect — the included portafilter and tamper feel a budget‑oriented and the pressurized baskets don’t deliver espresso as rich as you’d get from higher‑end machines — it’s a great performer for beginners or casual espresso drinkers. Upgrade the portafilter basket and tamper but for a more premium experience especially if using it daily. That said, the included accessories are perfectly fine for a casual user. Overall, this machine offers excellent value for the price. If you want a compact, easy‑to‑use espresso maker that consistently produces enjoyable drinks (especially milk‑based ones), this is a great choice. I am more than pleased with my purchase and you will be too. One thing that I learned and it’s the most significant piece of information I will pass along. You don’t need an espresso dark roast coffee for espresso. It’s your preferred roast, grind, and freshness that make the difference. Try your favorite roast in an espresso grind and enjoy!

Great buy, especially in its price range and perhaps even beyond
Color: A-Silver
Hope not to jinx it and have to change this review in six months but I'm extremely pleased with this machine. I've gone through two DeLonghis that lasted me each 4-5 years and I've liked them a lot, but both have eventually leaked and had quirks that were never ever answered/remedied by their customer service. I bought this Casabrews on spec, after looking through all sorts of alternatives, even hand models. I read through customer reviews, including the negative ones complaining about noise, its weight (or, rather lack of), claims over shoddy materials (its plastic components), alleged issues with its wand and basket, the quality of its shots, and so on. I was concerned about buying a product from a relatively new company with a short track record. But, OTOH, there were some very positive, persuasive reviews online. I'm from a coffee-producing nation and have more of it in my veins than blood so it's an absolute daily must-have that an increasingly leaking DeLonghi wasn't going to provide for long so I was facing an emergency. That this model was on sale at Amazon was a welcome incentive since, by the same token that I know what I like in coffee and scoff at the pretentious, opinionated coffee snobishness that too often characterizes conversations over it in the US, I've never been persuaded by the fancy-schmancy high-end, pocket-gouging machines on the market. While I've only had it for several weeks, I'm delighted with it. It's way faster than my old DeLonghis. I love that I don't have to hover over it watching to make sure it doesn't overflow because it turns itself off--and while I'm perfectly happy with the amount I'm getting without tinkering with it, it's programmable for longer shots. It's relatively quieter--noise complaints are likely from new users of espresso machines unused to their noise. It is lighter than my old machines, but the good news is that the basket fit loosens with use and a light hand on top of it solves the issue. The quibble about the basket falling from the wand seems to be more, again, about unobservant users who don't notice their design and the notch that locks the basket in place. It's also a preferable design than the wire in the DeLonghis, which would get loose and end up in our countertop compost bin when shaking out the puck. I even prefer the wetter pucks of used coffee it produces because they're way easier to scoop out of the basket than the DeLonghi's rock hard ones (even bent one of my demitasse spoons once). And, most importantly, the coffee is ABSOLUTELY FINE, even preferable to what I'd been getting from my old machines. And, hey, if it happens to have a short life, I'll just return and revise my rating and review.

Buono...squisito!
Color: Sterling Silver, Color: Sterling Silver
Arrive and packaged very well. It is lightweight...unsure if it's metal or plastic finished to look like metal...my guess is that "parts" are the latter because the knob for the froth/steam is plastic. Nonetheless, it is well made. Moreover, the price point makes it clear it can't be a premium expresso machine. I realize this doesn't sound like a great review of this product but on the contrary it is meant to say that - it is a quality machine based in the price point. I read the manual and personalized the settings for me and I have very little critique. The 2 in 1 portafilter is quality...the water dispenser "top fill" function is good; no need to remove the unit. Frother unit works well...just wish it pulled out a little more...drip tray could be wider as it's a little difficult getting a wide-mouth cup in without taking out the main tray...not a real hassle though. All in all....it's a 9.5 in my opinion. Functions are great...easy to understand and makes a great expresso, americano, latte and variable of each 👍👍 Great deal for the price!

Read the manual directions thoroughly to make the perfect cup.
Color: Sterling Silver
I’ve been using this machine daily for 9 weeks. I absolutely love it! It’s easy and delicious. It took about 90 minutes to thoroughly read the manual which was very helpful in making the perfect pressure crema. The machine quality is good. If it lasts several years I’ll rate it fantastic. That is tbd. It is a great value for the money and aesthetically pleasant sitting on the countertop. Love it!
