From what I've read the STL6 was the most clinical amp Genz made.
Their STL9 and the *.2 and MAX amps seem to be rated for their warmer and fuller tones.

Agreed. Plus the Shuttle 6.0 was attenuated down low to not destroy the little Shuttle Cabs!
If you side by side say a Shuttle 6.0 to a 6.2, you will see quite a big difference!
Genz make the Streamliner...which might appeal?
TC RH750?
Markbass LM3?
From what I've heard about the GK 'tone', it really is quite bright, quite growly when you want it to be, and in the case of their new micros (MB500/800) BIGGGG down low and very bright. E.g. a mid-scoop but this an be easily dialed out.
