dripping with vintage vibe, old production toshiba tubes provide an open yet mellow sound stage like a vinyl record

revered by guitar players for rich creamy sound reproduction which highlights the warm tube-eras precious metallurgy

involving beautiful clean tones that shine in low to mid gain apps, later breakup is harmonically rich and layered

defined lows relaxed mids and sweet highs, high musicality classic for preamps stereos tube mics and more hifi apps

whether its vocals instrumentals or percussion, the holographic sonic imaging of vintage toshiba are legendary
