Used Tube Works TD752 amplifier

The Tube Works TD-752 (also commonly labeled as the Tube Driver TD-752) is a hidden gem of 1990s amp design. Built in Denver, Colorado, it was designed by B.K. Butler, the legendary creator behind the famous Tube Driver pedal used by players like Eric Johnson and David Gilmour.

It is a hybrid, two-channel 100-watt guitar amplifier (available back then as a 1x12 combo or a standalone head) that features a distinct approach to blending solid-state power with genuine tube warmth.

Key Specifications & Architecture

• The Hybrid Setup: It combines a massive 100-watt solid-state power section with two entirely separate preamp topologies:
  • Clean Channel: Completely solid-state. It is incredibly clean, high-headroom, and crisp, serving as an excellent platform for pedals.
  • Tube/Overdrive Channel: Powered by a genuine 12AX7 preamp tube. This channel essentially embeds B.K. Butler's famous Tube Driver circuit directly into the amplifier, delivering thick, throatier overdrive with real tube compression.
• The "Mix" Switch: One of its coolest, most unique features is a manual toggle switch on the front panel that allows you to combine the Clean and Tube channels in parallel. This lets you blend the crisp attack and definition of the solid-state clean channel right underneath a heavy, saturated tube crunch.
