The Fender Tone Master ‘59 Twin-Amp JB Edition is Joe Bonamassa’s signature Tone Master amp—modeled on the late-’50s high-powered tweed Twin he’s used on stage and in the studio for years.
It captures the bold clean tones and hard-driven overdrive of that classic 2×12 tweed design, with modern Tone Master features that make it more practical for real-world use: selectable output power, two lightweight Celestion signature JB neodymium speakers, convolution reverb, an effects loop, and an IR line out.
