Boutique audio plugins made in Taos, New Mexico — built the way we master records: measure first, listen always. Every release is validated against its lab reference and ships with its measurement plots published, so you can see what you’re hearing.
Most plugins are tuned by ear and described by adjective. Ours start on the bench. The same four steps run for every product, and the measurements they produce are published with it.
Real hardware and the plugins people actually mix with go on a probe rig: stepped-level harmonics, aliasing, release shapes, program dependence. Numbers first.
Each character is fitted in a Python measurement lab against those numbers, at a calibrated −18 LUFS plane, so amounts read in measurement language rather than taste.
The fitted model is ported to dependency-free C++ — the engine that runs in your DAW — with oversampling wherever a stage can alias.
The engine must cancel against the lab model below −200 dBFS, in continuous integration, or the build fails. GTS Drive Strip nulls at −207.
Shipping DSP must cancel against its lab reference. GTS Drive Strip's C++ engine nulls against the Python model it was fitted from at −207 dBFS — float64 rounding noise. If it cannot, it does not ship.
Distortion plots generated by the same harness that gates the release, posted with the product. Lab output, not marketing claims.
Measured at 48 kHz on Apple silicon across a hundred instances. The cost is the always-on drive path; turning the whole feature surface on moves it by 14 %.
Serial + keyfile activation. No iLok. No subscriptions. Buy it once, keep it working.
The plugin line is built to be owned, not rented. That is a position, not a promotion, and it will not change with the catalogue.
Plain names for honest tools. One signature voicing family runs through all of them, and each ships with its measurements.
Transformer-drive channel strip. Seven measured drive characters in three banks, six compressor families fitted to the classics, delta monitoring.

Every plugin goes through a beta with working engineers before it ships. Join once and you get every open build by email, with notes on what changed and what to listen for — free, unlocked, and yours to test on real sessions. What you hear shapes what ships.
The free one-knob drive: Grit, Hearth and Gold from GTS Drive Strip's measured banks, auto-levelled, with a harmonic ladder that shows what it adds.
A transparent true-peak limiter: 8x true-peak detection, bit-identical below the ceiling, and a MATCH that compares at equal loudness so you hear only what the limiting did.
A sub-bass synth: a one-octave window, FAT for small speakers, three measured drive voicings and a kick duck that follows the kick.
Grit, Hearth and Gold from the measured banks on one knob, level-matched as you turn it. Free always and forever, no serial — see GTS Drive Lite. Join the list and you hear the moment it is ready, and first about everything after.
