He was born April 28, 1960 in Frederick, Maryland to Webster and Jeanette Lofton Ambush. He attended Urbana Elementary School in Urbana, Maryland, West Frederick Middle, and Frederick High School. After high school, he attended the University of Maryland at College Park. While studying psychology during the day, he was introduced to the Washington, D.C. music scene at night. Through word of mouth, he was recommended for the bass job with Spyro Gyra and filled the bass space after audition. He made his studio debut with Spyro Gyra in 1992 on the album "Three Wishes".
His main bass is an Ambush Custom five-string bass. The signal goes into a Whirlwind Selector A/B box, where it is split. One side of the box feeds a Korg tuner, while the other feeds a Countryman direct box. The signal is split again at the direct box. One side feeding the house and monitor consoles the other side is fed into the stage rig. On stage he uses an Eden Navigator preamp, fed into a QSC 3500 power amp, driving an Eden 4x10 cabinet. The cabinet is miked and fed to the house and monitor desks as well. The band uses an in-ear monitoring system, so a combination of the direct and miked signals are mixed in the monitors. As for effects, he sometimes use a TC Electronics chorus pedal and an EBS Octave pedal. In addition to the Ambush basses, he sometimes uses an Athlete acoustic bass guitar or a custom Jazz Bass with a Moses composite neck. In the studio, the bass goes direct to the console, and is combined with signal from either a miked Eden cabinet or the Navigator preamp. His home studio is a basic writer/project affair with Alesis ADAT, Mackie Board, Yamaha NS-10 and KRK KROC monitors, various keyboards, Alesis DM5 drum module, Hart Dynamics Multipad and kick drum triggers, a Power Computing CPU, MOTU Digital Performer sequencing software, and soon, Pro Tools.
