Description
Introducing the all-new 2025 Suhr SL15—a compact 15-watt powerhouse and the newest addition to the legendary, hand-wired SL Series. Designed to deliver the unmistakable character of classic British amps, the SL15 packs rich harmonic cleans, a chewy midrange, and searing vintage-style overdrive into a smaller, more versatile format.
From sparkling edge-of-breakup tones to roaring British gain, the SL15 offers punchy, articulate, and highly touch-sensitive response. Whether you're cranking it up or rolling back your guitar's volume, this amp nails the feel and sound of the golden era of British overdrive—with modern flexibility and convenience.
The SL15 features a single-input, dual-channel design that lets both channels run in parallel, allowing seamless blending. When one channel’s volume is dialed all the way down, it’s completely removed from the circuit—maintaining clarity and dynamic response. It's the best of both worlds: vintage crunch with modern control.
Key Features:
Fat-Cap Switch
A nod to a well-known amp John Suhr worked on in the '90s, the Fat-Cap adds low-end weight and punch—especially useful with the Treble channel. In previous SL models, the Fat-Cap was always engaged. Now, you have the option to switch it off for a more authentic, stock vintage tone.
Mid-Boost Switch
Add focused midrange presence and a subtle gain lift. The Mid-Boost increases the drive to the phase inverter and enhances the tone stack, delivering extra punch—especially effective when pushing the amp’s controls hard.
3-Way Bright Switch
Tailor your high-end response with three brightness levels:
• Off (original SL voicing)
• Middle (moderate brightness)
• On (full brightness, matching classic vintage amp specs)
This feature gives you ultimate control over clarity and presence, helping your tone cut through any mix.
