The Bassman Export model includes a multi-tap power transformer, allowing it to switch between voltages for international use, unlike standard Bassman amps.

This amp is appreciated for its extensive clean headroom, suitable for players who prefer unbroken clean tones even at higher volumes.

The Bassman 135 offers decent headroom and works well in higher-volume environments, making it suitable for live gigs with moderate stage volume demands.

For studio use, the Bassman 70 is favored for its warm tone, although it's mostly unused in studio settings where DI is preferred for bass.

A Bassman 100 or 135 model excels with a P Bass in funk settings, as evidenced by live performances where it complements the style effectively.

It's advised to have a technician inspect the amp due to potential issues like cut power cords and missing switching controls.

A 100-watt Bassman head paired with an efficient cab like a Peavey TVX410 can achieve loud, clean tones needed to play over drummers.

Modifying the filament rail with resistors can reduce filament voltage, potentially extending tube life.

In the U.S., the export model isn't usually valued higher than standard Bassman amps unless the multi-voltage feature is essential, increasing its rarity value.

This specific model, produced between 1967-1969, was notably used by Paul McCartney.
