I upgraded from the previous model. I like the new design better. Hartke has made it more flexible in connectivity and goes well with my LH1000. I play extended guitars and without the specs, my guitars would be compromised if I used standard guitar rigs. The full frequency range is necessary to access all the nuisance the instrument provides. Sure, there is no capability to ramp up overdrive with this set of equipment as you would with a guitar amp, but nothing a valve pre-amp pedal cannot solve instead. This is a whole different ball game for extended guitar players.
