Your HB-15GXD is a small solid-state practice amp with digital modeling — it lacks the valve compression and input-stage saturation Iommi got from overloading his Laney. Compensate by maxing the mid control and keeping bass near zero to replicate his scooped-bass, mid-heavy attack. The original Rangemaster boosted upper-mids before the amp; without a treble booster pedal, push gain higher on the OD channel to approximate that aggressive edge. Dropped treble slightly from Iommi's 10 because solid-state amps get harsh faster than valves.
