The Bass Master RB for Rockabilly Bass is the first double bass transducer system designed specifically for Rockabilly and Slap Bass. It combines two transducers (the Bass Max and a fingerboard pickup) to create an integrated double bass pickup system that brings out the percussive and subtle fingerboard sounds, as well as strong and warm bass tones. Each Bass Master RB can be fine-tuned via the separate bass and treble controls within the dual channel preamp, providing an infinite range of combinations for every player and any style of play. The first component, the popular Bass Max, is positioned in the bridge wing. To make the Bass Max, we combine two transducers into a "sandwich" in order to maximize and enhance vibrations captured from the entire bridge. Only one Bass Max is necessary to provide an even signal from all four (or five) of the double bass' strings. Its strong midrange signal is ideal for cutting through the mix in loud Rockabilly situations, or providing a warm and supportive line for country bluegrass.The fingerboard transducer's unique size and shape allows it to be precisely placed on your instrument. The preamp lets the player blend in just the right amount of slap, growl, and other fingerboard sounds to reach their audience. This allows the player to achieve the exact sound they desire.
The dual-channel preamp has internal gain, bass, and treble trim pots for each pickup, allowing impressive +/- 20dB tonal adjustments. External volume controls let you balance the volumes of the bridge and fingerboard transducers on the fly. A convenient belt clip is included with this compact preamplifier, which weighs a mere ten ounces with the battery installed. A six foot, high quality three conductor (1/4 inch stereo) cable is included to complete the package.
The Bass Master RB includes an extra output in the preamp, enabling stereo sound if desired.

The best frother I ever had
Color: White
I have been using frothers to make a daily matcha latte since 2016 and, since each of them lasted only between 4 to 12 months, I had purchased many of them.
This one is absolutely the best one! I bought it in July 2025 and I surely hope this will last more than one year. I will update my review if it stops working too soon.
But , for now, it has been great! I totally love the strong, fast engine. It perfectly whips up my matcha latte in just 3-4 seconds! As I use a very tall cup, I never experienced any overflowing of the liquid.
It feels heavy and stronger than my previous one, and I like that.
The reason I took off one star is because it doesn’t come with a metal stand considering that it is not possible to keep it standing up on the kitchen counter because, on the top, it has a robber cover that it is not flat. I am using an old stand from one of the previous frothers but, as this frother is much heavier, it keeps falling down. It would be nice to have a stand that fits this frother!
Other than that, so far, it is the best frother I have ever had!

Really powerful, responsive customer support
Color: Blue
Awesome for mixing protein powder into milk, Gatorade powder into water, making salad dressings, basically the kinds of work that would be overkill for an immersion blender. The unit I got started to vibrate like crazy after a few weeks. Contacted support and they said it was likely that the whisk rod was bent and said they'd refund me the cost of a new rod. We'll see if that solves the problem, but overall, I am impressed by their product and aftersales support.
