I understand that slap tones (and other tones) are subjective, this is a great amp but it does not do Marcus. I agree with Greg and others that it would be nice to see a second amp (leave the streamliner alone) with more tone options like hi-mids, more slap hi's and a global tone shaper but keep it simple.
Like say something like a Shuttle 9.0 or even perhaps maybe a Shuttle 9.2.
Genz better get on the move.

. Will post a picture when it's all together!
