The Quilter Block Series have set a new standard for tone, portability, and professional power! Our internal 400 watt or 100 watt class-D powerplant provides unparalleled power reserves, but no worries -- our fully effective Master control regulates peak power from zero to 100 or 200 watts, with no loss of tone or overdrive, so you can set the wattage to match your speaker ratings. The additional wattage provides voltage overshoot, tonal boost, and impedance flexibility, overcoming the typical limitations of "solid state watts". This is just one aspect of our incredible patented technology that combines boutique tone quality with unbelievable power that sits in the palm of your hand. Use with any good speaker, or pair your Block with one of our BlockDock™ series cabinets for the flexibility of a head with the portability of a combo!
