Mesa Subway TT-800 Bass Amp Head

Mesa Subway TT-800 Bass Amp Head: Tube Preamp with Class D Power Amp

The Mesa Subway TT-800 Bass Amp Head offers bassists an exceptional blend of classic tube tone and modern power amp performance. Featuring an all-new tube-driven preamp, this amp head allows you to experience the rich, blooming tube character of the legendary Bass 400+ tone stack architecture in the Boogie channel, or the modern tone of the award-winning Subway Channel. With enhanced tightness in the low end, accurate punchy mids, and crystal-clear highs, the TT-800 is designed to meet the diverse needs of today’s bassists.

Dual Channels for Versatile Tone

The TT-800 features two independent channels, allowing you to switch between them for different responses and sounds with one instrument, or dedicate each channel to separate instruments with different characters and needs. The Boogie channel delivers a classic, warm tube tone, while the Subway channel offers a modern, tight, and punchy sound. This versatility makes the TT-800 perfect for any musical style or performance setting.

Boogie Channel Features

  • Variable High-Pass Filter: 25Hz to 125Hz
  • Active Driven Passive 3-Band EQ: Bass, Mid with variable Mid-Shift Control, Treble

Subway Channel Features

  • Variable High-Pass Filter: 25Hz to 125Hz
  • Fully Active 3-Band EQ: +/- 12dB of Bass, Mid, and Treble with Sweepable (variable) Mid Frequency Control (150Hz-2000Hz)

Powerful and Lightweight

The TT-800 boasts an 800-watt output at 4 or 2 ohms and 400 watts at 8 ohms, powered by a lightweight Class D power amp. This ensures you have plenty of power for any gig, while keeping the amp head portable and easy to transport. The global Deep Switch and Bright Switch further enhance the amp's dynamic control, allowing you to fine-tune your tone to perfection.
