B27
An old signal path. A new sonic question.
An old tube preamp I don't want to reduce to a vintage knob. B27 is my attempt to rebuild its signal path as a plugin using historical documentation, published measurements and circuit simulations.
A look inside the plugin
Screenshots to follow. This space will show the B27 interface.
From circuit diagram to sound.
B27 draws on a tube amplifier developed in the late 1950s that later helped shape the sound of well-known recordings from the 1960s.
I'm using documented circuit details, published measurements and simulations to build an independent preamp plugin. Where questions remain, I keep testing and comparing until I'd want to keep the sound on a recording of my own.
An audio demo already exists. This product page is an initial draft; more detailed sound examples, screenshots and technical information will follow.
Documented circuit
Historical documentation and documented circuit details form the foundation.
Measurement and simulation
Published measurements and circuit simulations help shape the model.
Listen and compare
Open questions are still being tested and compared. Sound examples for this page will follow.
Questions & answers
Can I download B27 yet?
No public download is offered here yet. An audio demo already exists; information on public access will follow.
What will the plugin cost?
Pricing and the licensing model are not settled yet. This page is not a purchase offer.
Which operating systems and plugin formats will be supported?
Supported operating systems, plugin formats and system requirements will be listed once they are settled.
What is B27 based on?
A historical tube amplifier is the starting point, alongside documented circuit details, published measurements and my own simulations. These form the basis of an independent preamp plugin.
