Bass Cannon (Hand cannon/pistol)

This hand cannon fires pure sound waves (so it doesn't need ammo to function but charges instead), it has 6 charges before it must be "reloaded", you may use a bonus action to recharge the weapon, if all charges have been used you must recharge it using your next action.

When the Bass Cannon is fired the recoil is so great that it cannot be wielded by anyone with less then a strength of at least 16, as it will fly back and deal 1d10 bludgeoning damage to the user.

The Bass Cannon (when fired) fires a wave of condensed sound in 5 ft wide projectile of pure intense bass in the form of a force attack that deals 2d12 force damage. Because of the intensity of the bass fired from this weapon, it also deals 2d12 thunder damage, and a creature must roll a str and a con save with the DC for this weapon being 16 or the creature(s) hit with the projectile will become deafened (con) and pushed back 10 ft (str) If a creature succeeds on a saving throw, it is immune to the deafened effect if this weapon for 3 rounds(con) and not pushed back(str)

to attune this weapon you must sit with it in your hand while playing epic bass filled music for 4 hours without moving

It’s up to you to decide whether a character has proficiency with a firearm. Characters in most D&D worlds wouldn’t have such proficiency. During their downtime, characters can use the training rules in the Player’s Handbook to acquire proficiency, assuming that they have enough ammunition to keep the weapons working while mastering their use.
