The Fender Pro Amp 5A5 with field-coil speaker is an early narrow-panel tweed-era model featuring the rare field-coil speaker variant. Delivering approximately 15W through two 6L6 tubes, it represents the earliest incarnation of the Pro Amp line and the unique tonal contribution of the field-coil speaker — an electromagnetically powered driver that produces an even warmer, more compressed tone than permanent-magnet speakers.
