Subway TT-800 Bass Head


Two Separate Channels in a Dual Mono configuration feed the Subway® TT-800™'s muscular, articulate 800-Watt Class D power section and create the foundation from which to build your ultimate Bass Tone.


The TT-800 features an all-new tube driven preamp allowing bassists to experience the rich, blooming tube character of the legendary tone stack architecture from the Bass 400+ in the Boogie® channel or the modern tone of the award-wining Subway Channel with enhanced tightness in the low end, accurate punchy mids and crystal clean highs. These Channels can be used to switch between (Foot Switch optional) for different responses and sounds with one Instrument, or dedicated to separate Instruments with different characters and needs.


With our patch-point style independent Effects Loop design, you can also choose to run independent processing for each Channel/Instrument or substitute a favorite external preamp or modeler for one of the switchable Channels.
