User reviews

Love it!

Now I can get rare and discontinued pedals from BOSS all in one unit. Love it!

App keeps signing out. FIX THIS

The pedals sound like they should, quality is there. Integrates into my pedalboard seamlessly. Now onto the bad. Firstly, are you absolutely kidding me that there is not enough storage in this unit to house all the pedals??!!!?? That was a huge bummer. The fact that I had to delete a pedal in order to make room for my new DM-2 delay I purchased. Shame on you Boss. my suggestion would be to have a firmware upgrade that would allow these apps all to reside in the same pedal, which is what I’m guessing most consumers are under the impression this does, and that’s very misleading . I will do a YouTube review on this as well, please, this oversight is massive, it needs to be handled ASAP. No Five stars until this gets handled.

エフェクト選択

音色は概ね満足です。

ただ、デフォルトで入っている8エフェクトもアンインストール可能にしてほしいです。

現状だとアンインストール・インストールを選べるのが追加エフェクトのみで、エフェクト選択時に自分の使用したいものを瞬時に選択できず、スピードを求められる現場での使用に向いていないと感じてしまいます。

ユーザーとしては自分の使用するものだけをPX-1にロードし、その他は消せる状態にしたいです。

音色自体はどのエフェクトも好きなので、ぜひ改良をお願いいたします。

インターネットエラーって?

新しいペダルを追加したくてもアプリを開いてすぐ操作も出来ずエラーになり何も出来ない。初期状態のエフェクトで満足できる人向けのサービスです。
