The EQ section makes the difference! The LEHLE JULIAN offers additional controls like the parametric mids and treble which allow individual sound shaping.
The S-Mode: The LEHLE JULIAN does not have an S (= Sunday) Mode whith a higher input impedance.
SW as in Switcher: The LEHLE JULIAN has an On /Off footswitch included as a standard, which comes along with the big LED showing its status. Besides the classical LEHLE SUNDAY DRIVER without switch there is a switchable version, the LEHLE SUNDAY DRIVER SW.
