Frequently asked questions

Which one fits my bass?

The SMB-4DS is engineered specifically for Music Man StingRay basses and drops in as a complete replacement. The Apollo is designed for standard J-bass routes with 56 mm neck and 59 mm bridge string spacing.

Do I need a battery?

The SMB-4DS includes a 3-band active EQ circuit, so it requires a battery for tone shaping. The Apollo is fully passive and needs no battery.

Which is better for funk and slap?

The SMB-4DS is specifically optimized for funk and slap with its punchy ceramic design and dedicated slap switch. The Apollo excels in funk and rock but offers less genre-specific switching.

How do they handle noise in live settings?

Both use hum-canceling designs—the SMB-4DS via ceramic magnet hum-canceling construction, the Apollo via linear humbucking with vacuum wax potting. Both are stage-ready with minimal noise.
