5 Second Cassette Tape Loop – Upcycled, Hand-Built, RTM Tape

Hand-Built Cassette Tape Loops – Field Line Collective

Welcome to Field Line Collective.

Each of these handmade cassette loops is built from upcycled shells and parts — cleaned, reassembled with care, and loaded with brand new RTM C60 tape. A perfect balance of character and fidelity.

This listing is for our standard loops, available in your choice of 5 or 8 seconds. You’ll find a separate listing for each length in the shop.

These loops are ideal for experimental sound design, ambient composition, tape sampling, or simply getting lost in the rhythm of decaying repetition.

Every loop ships with a custom J-card and is housed in an upcycled case — a nod to archival aesthetics and DIY spirit. No two loops are quite the same, but each one is tested and tuned before it leaves the bench.

Coming soon: a modular, expandable tape loop design that opens up new creative territory. Follow the shop to stay in the loop.

Thanks for listening — outlive the format.
