SL68 50W Tube Guitar Amp Head

The Suhr SL68 tube guitar amplifier head brings you the full spectrum of classic British amp tones with modern dependability. With its handwired construction and custom transformers, the SL68 recreates those highly desirable vintage tones, from sparkling cleans to saturated overdrive. Its flexible design gives you versatility for the studio or stage.

Dial In Vintage-Inspired British Tones at Any Volume With the SL68

The SL68 guitar amp head delivers the coveted British tone that defined rock and blues, responding dynamically to your guitar's volume knob. Get clean headroom or rich, harmonically complex overdrive just by adjusting your guitar volume. The SL68's four unique inputs let you fine tune your tone for everything from brighter rhythms to warmer leads. Lower the power with the Variac setting for increased touch sensitivity and smooth distortion. With muscular EL34 tubes and a custom output transformer, the SL68 serves up the engaging sound and dynamic response that brings vintage British amps to life.

Access a Wide Range of Legendary Tones With Four Tailored Inputs

The SL68 gives you four input options to explore the complete spectrum of British amplifier tones. The Bright Channel I input accentuates treble for cutting chords and rhythm work. The warmer Channel I input smooths out the highs. Switch to Channel II's high sensitivity input for increased bass response perfect for solos. Or opt for its low sensitivity input for a balanced tone. Each input has its own character, allowing you to easily craft your ideal sound.

Get Touch Sensitivity and Harmonic Richness in Low Power Mode

One of the SL68's most useful features is its Low Power mode. Just like the famous "Variac" mod in vintage amps, power is lowered so the amp distorts more easily. You'll immediately notice the difference, with enhanced touch sensitivity, a looser feel and rich harmonic overtones. Cleans open up with sparkling definition. Overdriven tones take on a smooth, dynamic quality. It's one of the secrets to iconic rock and blues tones. The SL68 makes this mod easily accessible via its power switch.

Hear the Difference a Custom Output Transformer Makes

The SL68's custom output transformer is pivotal to its authentic vintage sound. Output transformers couple the amp's circuitry to the speakers, shaping tone and dynamics. After extensive listening tests, Suhr designed the SL68's transformer to sound clear, detailed and dynamic, with an authority that honors classic British amp heritage. From crystalline cleans to vocal-like overdrive, the SL68's transformer helps transport your tone back to the golden era of rock.
