Suhr SL68 Hand-Wired 100w Single Ended 4-Input Plexi-Style Amplifer Head
Each SL amplifier features hand wired construction, four inputs (Normal and Treble), Low/High power switch, Master Volume control (located on the back panel), and is powered by EL-34 power tubes and three 12AX7 preamp tubes.
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. We’ve spent countless hours listening to different transformers until the spec was finalized for our custom “PLEXI” output transformer. This transformer sounds clear, is dynamic, and lends authoritative authenticity to the amplifier.
Suhr SL amplifiers feature a Post Phase Inverter Master Volume control. 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.
