### 5/5 — Love it!

*2026-06-10*

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

### 1/5 — App keeps signing out. FIX THIS

*2026-04-06*

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.

### 3/5 — エフェクト選択

*2026-04-06*

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。

### 1/5 — インターネットエラーって？

*2026-03-25*

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。

### 4/5 — Works great!

*2026-03-10*

Not a single issue connecting to the pedal, updating its firmware and downloading the free pedals (…but it surely helps if you read the manual and follow the on-screen instructions 😉).
The app also contains additional information about each of the pedals and what the buttons do.
Only the font might be a tad larger…

### 1/5 — 改善無し

*2026-03-02*

アップデートがエラーで不可能。
プリインストールの8種類以外のエフェクトがインストールできない。
上記の改善策が提示されない。

### 3/5 — モデルパスが分かりにくい

*2026-02-02*

モデルを選んで購入して、またモデルを選ばなきゃ行けないし、選んでも第一選択肢が「購入」になってる。
購入履歴があるわけでもなく、0/1の解説もない。
複数台にインストール可能だから複数ライセンス買えるようにしてるのだと、後から分かったけど端末ごとに出す画面は ではその端末に対してのライセンスに不足があるかだけでよくて、足りてるならインストールの選択肢だけでいいのではないか。

### 5/5 — The PX-1 gets a lot of hate

*2026-02-01*

But I love mine. Just purchased the 3 new pedals. Easy process.

There are a few minor bugs in the pedal that I’m sure will get fixed in the next update.

### 3/5 — Good, but not enough storage???!!?

*2026-01-29*

### 5/5 — Bought at release

*2026-01-19*

I enjoy this pedal. The app does what it needs to do. No issues. Except, where are the new pedals? I want to buy them all! It’s January! Let’s Go!!
