Harley Benton TUBE15 & G112

Overview: Harley Benton TUBE15 & G112 Package

The Harley Benton TUBE15 and G112 form a tube amplifier head and speaker cabinet set designed for guitar players seeking tube tone and simplicity at a competitive price. Available since November 2023 and retailing at 291, this package comprises a 15-watt single-channel amplifier head and a 12-inch speaker cabinet. Let's break down both components technically for their real-world potential on stage, in the studio, or at home.

Amplifier Head: 15-Watt Class AB Tube Design

The TUBE15 amp is a 15-watt head utilizing a Class AB tube power stage. It is loaded with genuine vacuum tubes: three ECC83 (12AX7) preamplifier tubes and a pair of EL84 power tubes. This classic tube topology is engineered for dynamic, harmonically-rich guitar tones accessible even at moderate volumes.

• Channels: One channel with straightforward control options.
• Power Attenuation: Switchable between 15 watts and 1 watt, making it flexible for both rehearsal and recording where volume management is critical.
• Controls: The control panel provides Gain, Volume, Tone, Bass, Middle, Treble, and a spring Reverb, supporting both tonal shaping and in-amp ambience.
• FX Loop: An effects send and return set (6.3 mm jacks) accommodates integration with pedals or rack processors.
• Input & Outputs: Standard 6.3 mm jack instrument input, a 6.3 mm jack for a footswitch connection, and speaker outs supporting 8 or 16 ohms.
• Dimensions & Weight: Compact at 435 mm long, 245 mm wide, and 200 mm high, with a weight of only 6 kg (about 13.2 lbs).

Speaker Cabinet: G112 12-inch Model

Paired with the TUBE15 is Harley Benton's G112 cabinet. Its single 12-inch, 8-ohm speaker handles up to 100 watts (70 watts RMS), providing ample headroom for the TUBE15 and ensuring compatibility with more powerful heads if needed.

• Construction: Semi-open design, constructed from medium-density fiberboard for a balance of resonance and durability.
• Connectivity: Equipped with a single 6.3 mm jack input.
• Maximum Power: Capable of supporting most heads under 100 watts output without speaker strain.
• Dimensions & Weight: Measures 545 mm in length, 257 mm in width, and 453 mm in height. Weighs in at 11 kg (about 24.2 lbs).
• Accessories: Includes a 1.5-meter speaker cable with two 6.3 mm jacks and adequate wire cross-section (2 x 1.5 mm²).
• Handling: Fitted with a top handle for transport.

Technical Features in Detail

The TUBE15's tube configuration (three ECC83/12AX7 for preamplification, two EL84 for power) is a time-proven combination used in British-style amps favoring articulate cleans and high-gain drive. Class AB topology balances dynamic response with output efficiency. With only one channel, the amp avoids menu-driven distractions and focuses on direct, hands-on tone adjustment.

The 1-watt power attenuation option is practical for achieving tube saturation at bedroom volumes. Six control knobs and a spring reverb promise expressive, classic tube amp character with room for shaping bass, middle, and treble response. The effects loop will appeal to players using time-based or modulation pedals who seek clarity with high-gain sounds.

The cabinet's 12-inch speaker diameter is a standard for electric guitar amplification, blending low-end fullness with the clarity needed for diverse musical styles. An impedance of 8 ohms aligns with the TUBE15's matching output. The semi-open enclosure can broaden the sound projection slightly compared to closed-back cabs, adding depth to clean and crunch tones.

Applications and Usability

This amp and cabinet set is targeted at guitarists who want tube sound without unnecessary complexity. The power rating and attenuator make it equally suited for smaller live stages, band practice, or home studio use. The spring reverb is a traditional touch for those playing surf, blues, or vintage-flavored genres. The lack of a supplied footswitch is a notable omission, though the option to connect one remains.

The G112 cabinet's 100-watt rating ensures long-term reliability. At 11 kg, it remains manageable for transport, and the included speaker cable fits standard gigging needs. The black finish is understated, and the build aims for functional sturdiness.

Final Technical Impressions

The Harley Benton TUBE15 and G112 bundle is a practical, technically sound entry into tube amplification. The amp's wattage and features point to versatile use: from living rooms to rehearsal spaces, with enough headroom for moderate gigs. Tonal shaping and connectivity are straightforward, and the spring reverb adds analog charm. The separate G112 cabinet with its robust speaker spec and semi-open back ensures tonal compatibility and adaptability.

For the price, this package delivers true tube interaction and a real 12-inch speaker cabinet, addressing the core needs of many modern guitarists looking for simplicity, reliability, and genuine tube tone in a manageable format.
