RECOMMENDED — not currently owned; essential for the signature verse wobble
The Blues Junior's naturally scooped American voice requires boosting the mid control to 6 to emulate the Marshall JMP's British midrange. Treble is pulled back to 5 to avoid harshness on the EL84 power section, while gain is set to 4 to keep the Les Paul humbuckers right at the edge of clean breakup without fuzzing out. Because you lack a rotary cabinet or chorus pedal, the amp's built-in spring reverb adds necessary space until you add a modulation pedal.
