This isn't from your patch choice, it's from hitting the ramp twice which is qualifying the bass, which then allow access to the upper playfield to lock a ball. Collecting bra and underwear give double bonus for the rest of the game. Collecting Fender, Marshall, Gibson, and Vater lights extra ball.

Rules?

Yes

The Coma song mode is tough due to needing that target a number of times.

I would suggest:

Allow players to bail on the album modes at different levels of the modes by hitting the scoop (like the cashing out on the songs) so they don't need to survive long single-ball modes as a "reward". Same with Slash Solo.

Balance the song scoring. Songs later in the game are worth so much more than songs early in the game. If this is by design, the rules around it aren't apparent.

What's the deal with scoring when you manually change a song before starting it? Scoring seems to be too mysterious on this game.

Better lights for guidance on what to shoot when. For instance, on "hit the hurry ups" in booster multiballs, it's unclear what to shoot for.

Better visbility on song scoring potential before it starts (how long is ball saver?, what's the song level?, etc.)

Allow for collect extra ball with an orbit or upper loop shot when the magnet isn't working. Same with collect Axl.

I'm really scratching my head on the coma ball lock. Adding a mech that basically does nothing to improve, or even change, gameplay that becomes another potential problem area for no reason? Really glad the LE doesn't have this.

Yes, all of the points are in multiball (song modes)
