FS Genz Benz Neo Pak 3.5 In very good condition - works perfectly. Ill probably regret selling a NeoPak again down the road. Has some scratches - scuffs from normal use Still functions perfectly and looks good. Here are specs No it does not have 2 Ohm upgrade. Ultra Light 81⁄2 lb Design Analog 12AX7 Tube Preamp Digital SMPS (Switch Mode Power Supply) Class A/B High Current Power Amplifier Active EQ w/Parametric Mids 3-Band Signal Shape Circuit Tuner Out Active/Passive Input Limiter Circuit LED Status Indicators Speakon® and 1⁄4" Speaker Outputs Thermally Sensing Fan Cooling Full XLR Direct Out Interface Power 225w @ 8ohms /350w @ 4ohms 8.5lbs, 3 1/2" x 15 1/2" x 10 3/4" Selling just because I like the smallness of my Phil Jones D200 with a valve pedal. These are great amps and sound real sweet. This my second one and Id bet there will be 3rd one somewhere down the road when I become rich and famous. Ill try to get pictures up tonight. $245 shipped lower 48.
