The Subway TT-800 from MESA/Boogie brings the iconic punch and power of the all-tube Bass 400+ to the Subway series. This distinctive combination creates a powerful, portable package that highlights the unique personalities of both. Two separate channels in a dual mono configuration feed the Subway TT-800s muscular, articulate 800-watt Class-D power section. A tube-driven preamp allows bassists to experience the rich, blooming character of the legendary Bass 400+ in the Boogie channel or more modern tone in the Subway channel.

These channels can be alternately used with one instrument for different tones, or dedicated to separate instruments with their own character and needs. A patch-point style effects loop design also allows for independent processing for each channel/instrument or to substitute an external preamp for one of the switchable channels.
