But it separates it allowing for easy travel and more sound options. It is what gives your amp the volume it needs to play against a drummer or for live peformances. but your "Amp Tone" mainly comes from the preamp section. This is able to replace a large amp head for live performances and is loud enough to play with a drummer making for a portable solution. ( I used this for a deathcore band ) But you will need a preamp pedal like the Mooer Preamp Pedals or an fx processor unit like the Line 6 Helix going in before the Power Amp, (You must turn off all Cab simulation or Power Amp simulation and leave just the preamp section for this to sound the best) Then this goes out to one or two of your cabinets/speakers of choice. It has a Power Amp eq as well to shape the tone as you need. It also comes with headphone input so you can listen or practice quietly with the included Cab Sim
