Frequently asked questions

Q: How long are the loops?

Standard loops come in 5 or 8 second lengths — exact timing may vary slightly due to shell type and mechanics.

Are these pre-loaded with sound?

Nope — they’re blank and ready for your own recordings, samples, or experiments.

Are these new or recycled tapes?

Each loop is built from upcycled cassette shells and loaded with brand new RTM C60 tape.

Can I use these in a standard cassette deck?

Yes, but results may vary. Loops are best used in decks with stable motors and no auto-reverse.

Do you take custom requests?

I’m open to it! Feel free to message me with ideas or specific needs.
