Westbury 255 110 115 Bass preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Westbury 255/110/115 Bass models are a family of bass amplifier combos in various speaker configurations — 1x10 and 1x15 — sharing a common solid-state amplifier chassis. The different speaker complements allow players to choose between tighter, more defined low end (1x10) and deeper, fuller bass response (1x15). These models reflect the practical thinking that went into Westbury's value-oriented product range.
