The next step of evolution for the beloved SL Handwired series of amplifiers, Suhr introduces the SL68 MklI. With the addition of 3 vital switches and the all-new transparent Master volume circuit, the new SL MkIl series delivers the complete range of classic British tones at any volume. From sparkling cleans to screaming high-gain Variac™M* style overdrive tones, the S MkII Series responds dynamically to every nuance of your playing style and instrument with just a turn of your guitar's volume control. Fat-Cap Switch: One of the only tweaks found on a very famous amp John worked on in the 80’s, the Fat-Cap, adding low-end punch and bass that’s perfect when using the ‘Treble’ channel. In the original SL series, the ‘Fat’ cap was always in the circuit. This switch allows you to remove the Fat-Cap to get closer to a ‘true’, stock vintage amp. Mid-Boost Switch: Dial in the perfect amount of midrange punch to cut through the mix. The Mid-Boost give a bit more gain to the phase inverter and a subtle lift to the tonestack, boosting the gain to the mid range. Most useful when dimeing the controls. 3-Way Bright Switch: Add brilliance and sparkle to your tone, with clarity and presence. This switch allows you to choose between 3 different values, ‘Off’ is the original SL series, all-the-way bright which is the stock value found in vintage amps and a middle position that is somewhere in between. Say goodbye to the need for external attenuators. Suhr's redesigned Master Volume circuit gives you total control over your amp’s output, preserving your tones unique character, whether you’re in a bedroom jam or commanding the stage. This type of master volume control is highly effective at transparently controlling the output of the amp. When the control is at 10, it is completely transparent and out of the circuit. Start turning it down, and the amps volume can be reduced all the way to whisper levels. The three position power switch incorporates a low power Variac™* mode which lowers the amount of voltage available to the amp. This classic mod makes the amp feel much more spongy with a smoother attack and has been the foundation for some of the greatest rock tones of all time. To avoid having to re-bias the amp when switching power modes, SL amplifiers have two internal bias adjustments, one for HI power, the other for LOW. Output transformers have a major impact on tone. It’s the bridge between the output section of the amplifier and your speaker cabinet. Suhr spent countless hours listening to different transformers until the spec was finalized for their custom “PLEXI” output transformer. This transformer sounds clear, is dynamic, and lends authoritative authenticity to the amplifier.
