SuhrSL68 MkII 100W Tube Guitar Amp Head - Black
1/12
Independent shopping perspective
The Korena take
Suhr's SL68 MkII is a 100W all-tube head with a handwired British-style circuit, a custom Plexi-style output transformer, and a four-input, two-channel front end. Channel I takes the brighter route; Channel II adds a fuller, bass-forward option. Fat-Cap, Mid-Boost, and three-way Bright switches provide further shaping, while the master volume and Variac-style mode address output level and feel. With three 12AX7s and four EL34s, it is built around a direct, responsive amplifier format rather than a multi-channel control layout.
Strong match
Who this is for
- Moving between a brighter Channel I voice and fuller, bass-forward Channel II response.
- Adjusting low-end, midrange, and brightness with dedicated front-panel tone-shaping switches.
- Using the master volume and Variac-style mode to work at different output levels.
Consider the trade-offs
When to look elsewhere
- Rigs requiring more than the SL68 MkII's two amplifier channels.
- Speaker setups that cannot be matched to its 4-, 8-, or 16-ohm output settings.
