Metasonix

[1] Eli Crews, writing in Electronic Musician in 2008, commented that "Eric Barbour of Metasonix has a colorful approach to design, employing an all-tube audio path in his quest for unusual and sonically extreme products.

"[2] Barbour worked as an applications engineer for the Russian vacuum tube manufacturer Svetlana Electron Devices.

[3][5] Metasonix produces audio effects and synthesizers using atypical vintage vacuum tubes.

Metasonix modules are considered high-end in pricing and consume large amounts of power to create highly distorted sounds.

[6] Its products include the TM-7 "Scrotum Smasher",[7] the TM-3 voltage-controlled oscillator,[8] the TM-6 filter,[9] the TX-1 "Agonizer",[10][11] the TX-2 "Butt Probe",[12] the TS-21 waveshaper,[13] the S-1000 Wretch Machine,[14] and the G-1000 Fucking Fucker guitar amplifier.
