What is the difference between Lex and Lex mono input?

Based on customer feedback, in May 2012 we introduced an updated Lex design that includes an internal jumper allowing for selectable TRS stereo input, as well as non-click footswitches.

Lex mono input (now discontinued) was manufactured before May 2012 and includes a mono input.

Lex has:

– A serial number higher than S12-50000
– Non-click footswitches
– Internal jumper allowing for selectable TRS stereo input (more info here)

Lex mono (discontinued) input has:

– A serial number lower than S12-50000
– Footswitches with an audible click when pressed
– No internal jumper
