PRODUCT MANUAL
The SSS(SRV) is an expanded version of our standard Steel String
MKII, transforming it into a full-fledged amplifier circuit. The
SSS(SRV) is a 100% analog solid state preamplifier in-a-box with
an independent EQ section and five additional tone-shaping
controls beyond it's little brother, the Steel String MKII. The
SSS(SRV) is designed to go direct (DI) into your mixer/interface,
OR into your digital modeling amplifier (ex. Kemper, Line 6,
Headrush) to impart "tube" warmth and transients, OR in front
of your tube amplifier. No matter how you run it, the SSS(SRV)
delivers on its heritage, bringing the
3D clean and edge-of-breakup tones
we expect from a D* style amplifier.
