A Huge Hit in the Making! Finally on Sale - I’ve Been Waiting for This!

So, I’d like to introduce an item that I feel I absolutely have to spread the word about. I rarely write blogs about products, but this is one item I just can’t keep to myself.

PLAYTECH / BPA300

PLAYTECH / BPA300

That’s right, the legendary GPA100 has finally returned with a major power-up, now delivering 300W of output (at a 4Ω load).
So, just how amazing is this? Let’s say you have a bass amp that you really love, but its power is too low to use for live performances... With the BPA300, you have nothing to worry about.
Simply connect the BPA300 to the amp’s send terminal, and it becomes a high-volume amp that fills the room with a deep, rumbling low end.

It can also be used with loud-style 7-string guitars or when you want sufficient volume with drop tuning. Connect the signal from the amp’s direct out or line out, and you can play riffs that shake the ground.

I had another opportunity this time to test a sample, so I tried all kinds of things.

The first thing that surprised me was how incredibly flat the sound is, with almost no coloration.
The first thing I did to check the sound was to take a music signal from a mixer, input it into the BPA300, and listen through a monitor speaker.
Normally, instrument power amplifiers tend to have strangely boomy low frequencies, or their high frequencies are oddly cut or boosted, making them completely unsuitable for use in a monitoring environment.
But the sound quality of the BPA300 is something else. There are no strangely exaggerated frequencies, the highs extend naturally, and the noise level is extremely low.

However, the frequencies adjustable with the EQ are different from those of hi-fi audio, as they are tailored to the sounds produced by instruments such as guitars and basses.
Also, when using it with a guitar, distortion from the power amp needs to be taken into consideration. However, since it was originally developed for use with bass as well, it delivers 190W at an 8Ω load and 300W at a 4Ω load as specified. When using a Marshall 1960 at 16Ω, it can deliver a full 100W with absolutely no distortion.
It is already on sale, and sales have actually started to take off at quite an impressive pace.

When actually used with a guitar, the harmonics are easily produced, making the effects of modulation-type effects such as delay, reverb, and chorus particularly easy to hear.
With bass, it depends on the preamp, but there is almost no sense of stickiness. Instead, attack-heavy sounds produced with a slap or a pick come flying at you with tremendous force.
Because the sound is clear and flat, it is very easy to hear the character of the preamp being used.
Since the output frequency response is almost flat from 20Hz to 20kHz, with the EQ set flat, it is ideal for reproducing sources such as mixer monitors and keyboards.
For guitar and bass, simply boost or cut the EQ to your liking and shape the sound however you prefer.

Compared with the previous GPA100, it is more flexible and versatile, while also offering a massive maximum output of 300W (at a 4Ω load).
It is also equipped with a cooling fan, making long-term use possible.

The biggest reason I felt like writing this blog this time was the sound quality and the amount of noise.

Even after replacing the monitor power amplifier I normally use with the BPA300, there was absolutely no sense of anything being different. More than anything, it is incredibly low-noise.

When it comes to instrument amplifiers, I’m sure you, the readers, know better than anyone just how valuable it is to have no noise.
I have no doubt that this will become a best-selling product, so I recommend buying one as soon as possible.

Well then, please look forward to the next blog.
