Lehle - Sunday Driver SW

[H.A.M]

Here are some gut shots of a Lehle Sunday Driver SW (it says "Sunday Driver L v1.0" on the PCB).

The version without an on/off switch is already traced and there is a verolayout on the main page.

Comment from Joki / Lehle:
"Hey there,

to avoid confusion: the schematic you posted is from the SUNDAY DRIVER (neither doesn’t have a TS/TB button nor an on/off footswitch), while the product description is of the SUNDAY DRIVER SW.

So this one has the TS (True Sound) and TB (True Bypass) switching.
I'm wondering how different the schematic is compared with the switchless version.
