Redstone is the pefect companion on your ventures across the cosmos of sound.



Redstone Germanium Preamp


The Redstone is a flexible preamp with a 3-band tone stack powered by a vintage NOS germanium transistor. An homage to the early NASA launch vehicle, and an alternate reimagining of our Mercury platform, the Redstone is designed to be a stable and pervasive companion on your ventures across the cosmos of sound.

Using the Mercury as an inspiration to build upon, the Redstone offers additional control over gain, and tone compared to its older sister. The first stage and tone stack are built to closely emulate the input stage of a tube amp. The core gain cell is a discrete opamp with high headroom, capable of 40dB of gain. This beautifully integrated combination yields amazingly rich and detailed layers of harmonic sparkle, lending dimension and muscle to your tone when pushed.

The highly interactive tone controls offer plenty of bright bite, midrange clang, and thumping bass making the Redstone ideal for many purposes. When used at the beginning of your signal chain, it can function as a tweakable tone shaper, or even an overdrive. When used at the end of your pedal board the Redstone serves as an excellent line driver and boost. For those seeking a more transparent sound, the high and low controls can be lowered to minimum, with mid at noon, for a big natural rendering of your base tone. There’s also plenty of organic oomph for lower tuned instruments like basses and baritones to enjoy as well.

Hand-wired and built in Portland, Oregon, the Redstone features true-bypass relay switching with a soft-touch footswitch.
