Markbass TTE 501 Randy Jackson Signature – Technical Specifications

The Markbass TTE 501 is a premium, hibrid ‘Modern Vintage’ 500W bass amplifier head engineered in collaboration with world-renowned bassist Randy Jackson. Designed to deliver absolute analog warmth with modern gigging dependability, the TTE 501 features a genuine old-school tube preamp driven by three ECC83 tubes and a dedicated tube compressor utilizing an ECC81 tube. Power delivery is handled by Markbass’ innovative Tube Technology Emulator (TTE) power amp, giving bassists stadium-rocking power and harmonically rich dynamic tracking without the massive weight of a traditional all-tube head.
Key Features
• True Tube Heart Preamp: Powered by 3x ECC83 tubes, offering a classic organic feel, deep growl, and instant touch-sensitive responsiveness.
• Onboard Tube Compressor: An integrated professional studio-grade compressor driven by an ECC81 tube, providing everything from subtle leveling to classic pumping effects.
• Passive 3-Band EQ: A simple, musical passive tone-shaping section (Bass, Middle, High) that preserves the natural, uncolored characteristics of your bass guitar.
• Tube-Driven ‘Colour’ Filter: A specialized tube adaptation of Markbass’ famous VLE (Vintage Loudspeaker Emulator) control to easily dial in a warm, vintage old-school character.
• Tube Technology Emulator (TTE): A solid-state power section specifically tuned to emulate the power-stage sag, warmth, and compression of classic tube power sections.
