The SUBWAY ROCKET ushers in a new era of compact, portable and affordable combo amplification that boasts no compromise, quality construction throughout. Don’t let small size and the sparse layout fool you...the ROCKET is an extremely versatile single channel, Tri-Modal amplifier that provides a gorgeous clean sound, a soaring high gain lead and a giant, grinding crunch - way too big for its humble size. The Three Footswitchable Sounds (Modes) of world class personality housed in a Baltic Birch cab, along with our custom-designed magic ten inch SUBWAY speaker, make the ROCKET a mighty ally in the studio, rehearsal hall or anywhere else that you might be in need of Heavyweight Tone in a Bantam-watt arena. Its powerful foot-switching capabilities and all the Gain a player could need, make the ROCKET well suited for Rock, Pop, Country, Top 40 or any other style where versatility is the name of the game. Players who lean heavier in the Roots or Blues direction may want to take a look at the ROCKETS' older brother, the SUBWAY BLUES. This simplified SUBWAY focuses on power section clipibility with a Tone-packed, stripped pre-amp perfectly matched to the same twenty-watt burner. Looking to the ROCKETS' Rear Panel assures that your interfacing needs are covered. A parallel Effects Loop with a MIX Control provides tone insurance for even those questionable effects. Three speaker jacks (one 8 Ohm and two 4 Ohm ) are provided to ensure the proper impedance match to the many types of speaker enclosures. A RECORD / PHONE OUTPUT JACK is provided to capture the ROCKETS' soulful character direct to tape or into your own personal headset. The SILENT RECORDING MUTE SWITCH LOCATED TO THE LEFT OF CENTER ON THE CHASSIS’ UNDER SIDE and just beneath the Rear Panel, is a handy feature for those late night sessions when live speaker volumes are just too loud or not needed. As you can see, the ROCKET provides all the features any demanding pro could need and at the same time remains simple to operate.
