You have two multiball chances to set up Monsters of Rock before you light Monster Bash.
First chance is Mosh Pit if you set it up early. Then Frankenstein. After you've gotten those two then you move onto starting Monster Bash and completing the remaining instruments during Monster Bash.
You don't want to complete all instruments before you start Monster Bash. Rock before Bash is not worth it at all. You get a paltry amount of points. And if you start Monster Bash, you get the ball save for that, then if you start Monster of Rock during (or after) Bash you get an additional ballsaves.
Mosh Pit activates from the scoop so you're always in danger of accidentally activating it if land the ball there. I prefer to get a few monsters within a shot or two of being activated and then light Mosh Pit Multiball. Mosh Pit is great because it stops timers and has two add-a-ball features with lots of ball saver. Also if you are playing with Extra Balls enabled then you want those 12 shots through the center lane to light the Extra Ball award at the scoop.
Mummy is the easiest to complete when brought into a multiball as every ball put into play goes right from the shooter lane into the pop bumpers. You make a shot or two or use a monster bomb and this mode is rather easy to complete.
Dracula is another monster that is very safe to be completed in multiball. Any drains off of him can be ignored during the ball save. And during frenetic multiball play you'll often score random hits.
Bride for me is the hardest monster to get the instrument lit for by far. I usually need tons of monster bombs, luck, or a multiball mode. Getting Bride completed during singleball play is usually really difficult because the timer only stops when you hit the center lane. And the center lane doesn't actually progress the mode. So you have to chose between finishing Bride or trying to reset the timer. And even then you can only reset the timer three times and then it's really a race. This mode is a must to pull into Frank or Bash. Those Bride ramps are tough.
Creature is the easiest in single ball play if the return from the Creature scoop is consistent. I've seen lots of player just loop that shot over and over.
Wolfman can be dangerous when the ball goes through the entire orbit at lighting speed. Trying to get into control can be a chore. If you're a control player and the tilt isn't strict this mode isn't too bad to complete. But on a tougher machine or on an off day skill wise you might want to wait to activate this mode.
I usually start two or three modes, pull them into Mosh Pit, and then try to complete those modes. Then I start two or three more modes and then pull them into Frank and try to complete them. After that I start the last one or two modes and then start Monster Bash. While in Bash I try to start Monsters of Rock and come out of Rock cleanly with no Monsters or Instruments lit.
