Shure SM58 Custom Cover Guide: For Singers, Speakers and Live Use

The Shure SM58 has been the world's most-used live vocal mic since 1966. It's on every stage, in every conference room, on every pub karaoke night in the UK. The stock metal grille is fine — but for two specific use cases, it's not enough.

When a stock SM58 grille is fine

• Studio overdubs (one singer, controlled environment)
• Practice and rehearsal
• Any situation where the mic is one person's personal mic and never gets handed around

For those, leave it alone. The Shure grille does its job.

When you need a custom cover instead

Use case 1: Branded stage presence

If you're a performer, speaker, or band, the stock chrome grille tells the audience nothing about who you are. A custom-printed foam cover puts your name/logo on the most-photographed object in your show.

For touring acts, this matters more than you'd think. Stage photos with your branded mic on the front circulate Instagram far longer than the show itself. Cost: £25. Marketing value over a year of gigging: significant.

Use case 2: Multi-speaker hygiene

For conferences, panels, churches, and Q&A events where a single mic gets handed between multiple speakers, a foam cover gives the visible reassurance of cleanliness. You replace the cover between sessions (£20 each, cheap) — the mic itself stays clean.

Post-2020, this isn't optional for many venues. Speakers actively refuse to use a shared mic without a fresh cover.

SM58 dimensions

• Internal diameter: 52mm
• Recommended height: 55-65mm (live-use is usually shorter than podcast covers — less branding space but better mic-handling balance)
• Foam type: open-cell PU foam, slightly denser than podcasting foam (needs to survive sweat and handling)

What's different about a live-use cover

Stage covers have to survive things studio covers don't:

• Sweat absorption. Singers sweat into the foam. A cover that absorbs and doesn't dry out smells bad within 2 weeks of touring.
• Handling impact. Live mics get dropped, hit the cymbals, and survive shoulder-bag transport. Cheap foam disintegrates within a tour.
• Light cleaning compatibility. Live covers need to handle the occasional wipe with an alcohol wipe between speakers. Most podcast covers can't survive this — the print runs.

We use a slightly different foam composition for our SM58 covers vs SM7B covers for exactly these reasons.

Common live-use scenarios we ship for

Solo musicians and bands — single SM58 cover per mic, branded with band logo. Some bands order a pair (one for the mic, one as a spare).

Conference and event venues — order 5-10 covers in batches. Use a fresh one for each speaker/session. Stamp the venue or sponsor logo on each.

Churches and worship spaces — typically multi-host. Matching covers across mics, branded with church name.

Wedding suppliers (officiants, MCs) — single cover with their logo, used across multiple events.

Karaoke and pub venues — single venue cover, replaced every 3-6 months as wear accumulates.

What to ask before buying

1. What's the mic handed around? Yes → choose a slightly denser foam (we'll spec this).
2. How often will it be cleaned? Daily wipes → tell us, we'll use a more solvent-tolerant foam.
3. Will it be on stage with lighting? Lots of stage lighting → consider a darker base colour (white foam yellows under UV).
4. Is it primarily for branding or for hygiene? Branding-only is the standard. Hygiene-only might prefer plain white foam without print to reinforce the "fresh" message.

Where to buy in the UK

We make SM58 covers in our London workshop — browse the SM58 product page or contact us for bulk pricing on 10+ covers. Standard turnaround is 3-4 working days from approved artwork. Volume orders (25+) ship within a week.

Alternatives: Etsy generalists exist but turnaround is variable and quality control is hit-or-miss for live use specifically. For studio-only use, generic foam works fine. For live, made-to-fit makes a real difference.

Bottom line

The SM58 is a workhorse. A custom cover turns it from a generic mic into your mic. If you're touring, presenting, hosting, or running multi-speaker events, this is the cheapest brand upgrade you can make to the most-photographed prop in your kit.
