Suhr SL-15 Electric Guitar Amplifier Head - 15W

The Suhr SL-15 is a compact, 15-watt handwired amplifier head that delivers the renowned tonal quality of the SL series in a more manageable format. Built with a focus on capturing the essence of vintage British amplifiers, the SL-15 offers harmonically rich clean tones, a pronounced midrange, and dynamic overdrive - all with the detail, responsiveness, and character expected from a high-end handwired circuit. Designed for players who demand touch sensitivity and tonal control, the SL-15 is equally capable in both stage and studio environments.

Unlike traditional two-channel amplifiers that require channel-jumping or input switching, the SL-15 features a single-input circuit with blendable voicings. This design allows both channel characteristics to remain active simultaneously, offering seamless tonal blending. If one channel's volume is set to zero, it's removed entirely from the circuit, preserving signal clarity and response. This gives players a simple yet effective way to shape their tone without sacrificing dynamics or usability.

The amp includes three onboard voicing switches for additional tone sculpting. The Fat-Cap switch adds low-end depth and is particularly effective when using the 'Treble' channel. This switchable feature replicates a rare circuit mod from a well-known amp Suhr worked on in the 1990s, giving users the option to include or bypass the low-end emphasis for more vintage accuracy. The Mid-Boost switch enhances midrange presence and overall gain by adjusting the phase inverter and tone stack, which is especially useful for cutting through dense mixes. Finally, the 3-Way Bright switch offers tonal flexibility with three selectable brightness levels - from the stock SL setting to a vintage-correct bright mode, plus a balanced in-between option for fine-tuning high-end clarity.

An advanced Master Volume control gives precise command over output levels without compromising tone. Designed for transparency, the Master Volume maintains the amp's natural tonal character at any setting. When set to full, the control is completely bypassed, delivering an unfiltered signal. Turned down, it allows for low-volume playing while preserving the feel and dynamics of the amp - ideal for home use, rehearsals, or smaller venues without the need for external attenuation.

Powered by a 6V6 tube-based output section and three 12AX7 preamp tubes, the SL-15 delivers warm, articulate tones with excellent headroom and punch. The 6V6 design offers a balanced and responsive feel, closely mimicking the tonal footprint of higher-wattage amps but with earlier natural breakup and lower overall volume. This makes the SL-15 a versatile option for guitarists who want classic British tones in a handwired, portable format without compromising on performance or sonic integrity.
