Howard Roberts wanted an instrument he could really hear acoustically when he designed his namesake instrument, and decided on the oval soundhole instead of traditional f-holes. In fact, the first batch of Howard Roberts guitars made by Epiphone, Gibson's sister company, were very acoustic in nature, featuring both the oval soundhole and a carved solid spruce top.
According to Howard Roberts himself, these Epiphone models were "a little too expensive and a little too fragile." The subsequent versions by Gibson, like this Steve Miller-owned piece, had bodies made entirely out of maple.
In addition to the standard volume and tone controls, a mid-range roll-off control was also standard on the Gibson Howard Roberts, but many players didn't find it useful and ended up disconnecting it from the circuit.
I thought it was pretty cool that Gibson decided to retain the elaborate Epiphone-style pearl inlay on the Gibson Howard Roberts headstocks -- there's some fine, old-world craftsmanship for you!
