The Love Guitar Rod (ラブギターロッド Rabu Gitaa Roddo?) is Cure Beat's main weapon. Unlike the Cure Belltiers, the Love Guitar Rod has two modes which Cure Beat utilizes for battle. These modes are the Guitar Mode, on which Cure Beat uses the Love Guitar Rod as a normal guitar to dispel attacks or protect people from then, and the Soul Rod Mode, on which she uses it to amplify harmony energy and unleash a powerful purification attack which in this case, is the attack Heartful Beat Rock which will purify a Negatone.
Like the Cure Belltiers, the Love Guitar Rod is powered by a Fairy Tone, mainly Sory. Two extra attacks can be used when Lary enters the the Love Guitar Rod: Beat Barrier and Beat Sonic. Beat Barrier creates a force field around her to protect herself and others, although it may shatter if the attack is strong enough. Beat Sonic creates notes made out of energy that attack the enemy.
- In Love Guitar Rod (romanized as Rabu Gitaa Roddo) mode, Fairy Tone Lary (romanized as Rarii) enables Cure Beat to perform the attacks Beat Barrier and Beat Sonic.
- Fairy Tone Sory gives Cure Beat the power to switch it to Soul Rod mode to perform the purification move Heartful Beat Rock.
- The Love Guitar Rod is the fifth Pretty Cure weapon to be based on an instrument, the others being the Flower Tacts, the Shiny Tambourine, the Pine Flute and the Passion Harp.
- The Love Guitar Rod's design takes cues from rock-music related instruments, mainly electric guitars used by rock bands.
- Beat Sonic could be a powered up version of Ellen's ability to manipulate energy into a note shaped projectile.
- The official commercial for the Love Guitar Rod is a particularly interesting one: it features a little girl cosplaying as Cure Beat leading a flash mob, and it was so far the only commercial to have its BGM featured in a soundtrack (as the fourth bonus track).
