Mesa/Boogie Triple Crown TC-100 Tube Amp Head – Custom White Finish

📝 Description

Up for sale is a pre-owned Mesa/Boogie Triple Crown TC-100 100-watt all-tube guitar amplifier head in a rare custom white finish with a split black carbon-style front panel.

Most Triple Crown TC-100 amplifiers were produced in the standard black covering. This custom white configuration is considerably less common and provides a distinctive appearance that stands out from typical examples.

The TC-100 is a three-channel amplifier offering Clean, Low, and High channels, each with independent gain, equalization, presence, master-volume, reverb-level, and Multi-Soak power settings. Each channel can be individually operated at 3, 7, 20, 50, or 100 watts, allowing the amplifier to move from lower-volume playing and recording to full stage output. Mesa describes it as a 100-watt, three-channel tube amplifier with channel-specific Multi-Soak attenuation.

Important Condition Note

The custom white covering remains attractive overall, but with visible discoloration and handle wear.

Please review all close-up photographs carefully, as the cosmetic wear is intentionally documented.

🧪 Testing Information

The amplifier was powered on and allowed to warm up. The tubes and front/rear indicator lights illuminated as photographed. A Complete amplified sound test through a properly matched speaker cabinet was not performed. The channels, speaker outputs, reverb, effects loop, MIDI functions, CabClone output, Multi-Soak settings, and other controls have been tested. No footswitch or speaker cabinet is included.

Tube amplifiers should be operated with the appropriate speaker load and impedance selected unless being used exactly as permitted by the manufacturer’s CabClone and speaker-off instructions. The TC-100 provides selectable 4-ohm and 8-ohm speaker operation.
