SuhrSL67 MKII 50W Hand-Wired Tube Guitar Amp Head Black
1/4
Independent shopping perspective
The Korena take
Suhr’s SL67 MKII is a 50-watt RMS tube amp head built with two EL34 power tubes, three 12AX7 preamp tubes, a hand-wired turret board, and a custom Plexi output transformer. Four inputs, a master volume, FAT, BST, and three-position BRT switching provide several ways to set the front end. Low-power Variac mode changes the attack and compression, while two speaker outputs and a 4-, 8-, or 16-ohm impedance selector handle speaker connection. It measures 26 by 8.25 by 10.25 inches and weighs 42 pounds.
Strong match
Who this is for
- Using the master volume to set output level while retaining the amplifier’s described character.
- Connecting speaker cabinets through either of two outputs after matching the impedance selector.
- Exploring the lower-power Variac setting for its smoother attack and more compressed response.
Consider the trade-offs
When to look elsewhere
- Players who need a combo amplifier with an integrated speaker.
- Setups that cannot accommodate a 42-pound amplifier head.
- Players who do not have a speaker cabinet to connect to the head.
