I get commissions for purchases made through links in this post. Read more

Many P-Series variants underwent revamps over the years. Which between Yamaha P45 vs P45B, presumed by most as an example of an upgrade, is the better buy? 

With over a hundred years under its belt, Yamaha is arguably the world’s most famous digital piano manufacturer. And the P-Series, the brand’s entry level, is a huge favorite among beginners. 

The P45 is highly acclaimed for numerous reasons – it has full keys, satisfactory functionalities, and is quite inexpensive. The P45B, as anyone would correctly surmise, is pretty much the same. But unlike the usual misconception, the designation “B” does not mean that it is an upgrade. It actually stands for ‘black’, the color of the device. 

The Yamaha P45 vs P45B match-up is not a significant head-to-head. But if you’d like to find out which of the two is preferable, continue reading below.

Yamaha P45 vs P45B: Head-to-Head Comparison

As aforementioned, the Yamaha P45 vs P45B match up is not exactly consequential considering the only real difference between the two, other than the additional letter in the variant name, is the finish. The former comes in a few colors while the latter is just black, hence the “B” in the model’s name. Do note though that even the basic one comes in black as well. 

It’s quite amusing that Yamaha had to make this specific distinction, but it does seem like it’s a smart marketing method to re-release an old product. Whatever the actual reason for this is, the verdict comes easy. These two are on equal footing. 

Feel and Playability

The Winner: Tie

Although the P45 is just the second model designed under the P-Series right after the P35, Yamaha has given it a lot of thought, especially in terms of feel and playability. Again, our featured variants are exactly the same so this, and the following chapters, would just be a straightforward description.

+Hammer Action

Yamaha equipped both the P45 and the P45B with the proprietary Graded Hammer Standard (GHS) hammer action. “Graded” is almost identical to “weighted” in the sense that the keys are heavy under the fingertips. The main difference is that the left side has a lot more give than the right most side. The two were also provided with escapement, adding to the realism of the sound. 

+Touch Sensitivity

Sensitivity refers to the fullness of sound generated based on the pressure applied to the keys. Slow, soft presses give mellow tones while hard, forceful ones create booming resonance. This attribute is very much apparent in acoustic pianos because of the mechanism under the keys. Many digital versions fail in this because they lack or have very little weightedness. Fortunately, the two P-series have four levels: Soft, Medium (standard), Hard, and Fixed. 

+Key Texture

The keys on grands and uprights are either crafted from real ivory or polished hardwood. Some high end digital ones are furnished with high-quality plastic with ivory-like veneer over it, to achieve realism. The P45 and the P45B, unfortunately, are just made of plastic. 

Tone

The Winner: Tie

Equally as important as the feel, the tone is another feature most musicians look for when buying digital pianos. The closer it sounds to a grand, the better it is. Our featured P-series models, identical in practically everything, are on a par in this section as well.   

+Tone Generator

While real acoustic pianos have convoluted mechanisms under the hood to create sound, digital versions basically rely on recording that sound, storing it in a computer box, and playing it back when the keys are pressed. 

Companies have different names for their sound engines, although the system is practically the same. Yamaha makes use of the AMW (Advanced Wave Memory) Stereo Sampling for most of their P-Series models. But because Yamaha has very nearly perfected this, you can expect brilliance, resonance, melodiousness, and complexity when playing. 

+Sound Library

Aside from capturing acoustic piano sounds, digital versions can also play other instruments. This is especially useful for musicians who compose or perform. 

The P45 and its twin are furnished with 10 different voices: two grands, two electrics, two pipe organs, two harpsichords, a vibraphone, and a set of strings. 

Piano Functions and Features

The Winner: Tie

Pardon the repetitiveness, but the P45 and the P45B are perfectly matched in this chapter. They are truly one and the same as evidenced by the feel and tone as mentioned above and what will be detailed below. 

+Polyphony

The P45 is the second model designed, marketed, and circulated under the P-Series. Its predecessor, the P35, is not a bad piece. However, its 32-count polyphony left a whole lot of people – even beginners – wanting. Both the P45 and the P45B satisfied that deficiency since its polyphony was boosted to 64. 

Many will argue that good digital pianos should have at least 100. In this day and age, and with so many new competitors coming up with comparably great pieces, I may agree. But beginners will still benefit from a 64-count polyphony Yamaha.   

+Playing Modes

Often overlooked, this feature is incredibly important for beginners. The Lesson mode splits the digital piano in two 44-keys with the same octave so student and teacher can play side by side. Split does the same except each 44-key plays a different voice. Dual allows two voices to be played at the same time. Both the P45 and the P45B have Lesson and Dual modes. 

+Speaker System

The P-series models, quite unfortunately, only have two 6W power. This pales in comparison with its contemporaries. Worse, the speaker cones are downward facing. 

+Connectivity and Recording Capability

Aside from the headphone connections which is a must-have in any modern digital piano, both the P45 and the P45B have a USB port which allows users to connect to computers. While the instruments can’t capture practice sessions on the spot, adding the USB enables recording music and saving it to your PC or mobile phone.  

One of the functionalities many hope this would have is an AUX out for better amplification because the speaker is not as amazing as it should be.

Yamaha P45 vs P45B: The Similarities

From the feel and tone to the various features and functionalities, the featured P-series variants in this review are the same. The “B” (which stands for black) does not make a significant change, that is why this head to head between Yamaha P45 vs P45B is too close to call.
