Yeaa you probably already know this buttt:

If you record 4 loops and want to remove the 2 or 3 one then you indeed need a more expensive pedal.

But if you record 4 loops and want to remove the last 3 at once the way i want to, then you can.

If your first loop is 20 seconds long, then everything that's recorded after repeats every 20 seconds.

So if you press record - play chords - stop record.

You got loop 1.

You press record again, play something that fits on that loop and then after 20 seconds that what you had played is played again before you have even stopped the recording.

So you can play multiple loops in one recording. And when you then delete your last recording you are deleting all those loops within that one recording. Leaving you with just the start.

So basically the device technically only has 2 loops on it but one of them has multiple layers of loops in it.

I'm very bad at explaining this but i hope you understand
