Goodness in, Goodness out.
Welcome to Sosomotto. 
Here you will find the best quality tube based amplifier that faithfully reproduces the input signal. No tonal variations are added whatsoever. The signal is sent through custom matching transducers likewise designed to add zero tonal color.   Then they're all wrapped up in custom live-in road cases for years of durability. 
This is Sosomotto. 

Goodness in, goodness out.  
Made in America, one at a time.
