The Fender Tone Master '59 Bassman is a lightweight digital modeling amp that faithfully replicates a vintage tube Bassman but with modern features like built-in reverb and an effects loop. It includes classic controls like Normal/Bright channels and a 3-band EQ, along with modern additions such as a "Vintage-Tight" switch for bass response, power attenuator, and a balanced XLR line out with multiple cabinet impulse response (IR) options. The amp features four 10-inch Jensen P10R speakers in a lightweight pine cabinet and uses a 200-watt Class D solid-state power amp to mimic the 45-watt output of the original.
