Offered is a vintage Univox U-1236 E3 all-tube amplifier head, manufactured in Japan during the late 1960s. Originally marketed as a bass amplifier, the U-1236 has become a favorite among guitar players for its warm clean tones and rich vintage overdrive when pushed.

Condition

The amplifier is in very good vintage cosmetic condition with normal wear from decades of use, including minor scuffs and edge wear to the tolex. The faceplate lettering remains very present and all original control knobs are intact.

The chassis is clean and shows no evidence of abuse or major modifications beyond the safety upgrades described above.

Original Components

The amplifier still retains its original electrolytic capacitors. It is currently operating quietly, but because these capacitors are original, future replacement may eventually be desired as part of normal maintenance on a vintage tube amplifier.

Sound

Produces warm vintage clean tones with excellent dynamic response and smooth breakup as the volume is increased. The Deep and Sharp switches provide useful tonal shaping, making this a versatile amplifier for guitar, bass, harmonica, or studio use.
