As a bassist, Meros' musical influences are varied, including Paul McCartney, John Entwistle, Chris Squire, James Jamerson, Marcus Miller, Francis "Rocco" Prestia of Tower of Power, Chuck Rainey and David Hungate.

He played bass trombone and tuba in the University of California Jazz Ensembles, 1974–1977, under the direction of Dr. David W. Tucker.

His main creative venture since 1993 has been recording and touring with the critically acclaimed progressive rock band Spock's Beard, that to date has released thirteen full-length studio CDs plus a large number of live CDs and EPs, Videos, DVDs, and rarities collections.

Dave's current bass for Spock's Beard is a custom built hybrid between a Fender and a Rickenbacker.

Further customizations include a Full Contact Hardware bridge and a Hipshot Xtender tuning key that will detune the E string down to a D at the flip of a lever.

More recently, after the neck began delaminating from the body, it was completely rebuilt and refinished by Ed Roman Guitars, a company based in Las Vegas, NV.
