KMA Audio Machines Astrospurt, Boutique, Hand-Crafted, Four-stage JFET Based Phaser Pedal

Vintage phaser pedal lovers rejoice! No longer do you have to worry about those embarassing volume drops that are common amongst our favourite vintage phasers, thanks to KMA Audio Machines and their amazing Astrospurt: a boutique, hand-crafted phaser pedal that's out of this world!

4-Stage JFET Design, Perfect for Guitar or Bass

The cleverly designed, highly versatile Astrospurt isn't your typical "vintage-style" phaser: KMA Audio Machines have been kind enough to include more than your typical phaser controls.

Versatile Controls

Featuring Signal, Emph, Mix, Depth and Spurt control knobs, as well as a two-way Mode switch, the Astrospurt can produce sounds ranging from a nice, subtle sweep, right up to what can only be described as sounding like a beat-boxing guinea pig (and that's not a criticism, I love it!).

Internal Controls

As with other KMA Audio Machine pedals, the Astrospurt houses an internal control for fine-tuning. This 4-fold, internal DIP switch allows you to drastically change your tone should you wish, so use with caution!

Handmade Boutique Construction

Each and every KMA Audio Machines pedal is designed, assembled, silkscreened, tested, and numbered, by hand in a small Berlin workshop. Despite the premium-grade components and boutique construction though, pedals like the Astrospurt remain an affordable option for most working musicians and tone enthusiasts alike.

If you have any queries regardining the availability of the KMA Audio Machines Astrospurt, feel free to contact our online sales team directly.
