1 Wade H 2 weeks ago My new Boss amplifier arrived today, a second generation Boss Katana 100 watt 2x12" custom speakers, with a GA - FC foot controller.These are really great amplifiers, with some incredible features. 5 different "Amp Type" settings, 3 different output power settings 0.5 watt, 50 watt and 100 watt. Access to 58 Boss effects, with 15 effects on board simultaneously. The amp also has two angled "feet" that tilt the front of the amp upward when desired. On the back - Line out, headphones out, effects send and return, expression pedal in, foot controller in, USB - B in.On the top knobs left to right - Amp Type (Brown, Lead, Crunch, Clean, Acoustic), Gain, Volume. Equalizer - Bass, Middle, Treble. Effects - Booster/Modulation, Delay/FX, Reverb. Tone Settings - CH1, CH2, CH3, CH4 buttons, Presence, Master Volume, Power Control, Power On/Off.Effects are fully addressable by top knobs and through Boss Tone Studio Software. This amp weighs in at 42 lbs, much less than my old Fender tube amp, which weights as much as a bag of cement mix!
