MB Studio Caliber footswitch

Post by ctavares » Tue Jun 01, 2021 12:52 pm

Hi
I have a Mesa Boogie Studio Caliber amplifier, which I really like.
I bought it without a footswitch.
Recently I found a MB Mini Rectifier footswitch. However, it does not change the channels (Rhythm/Lead), despite switching ON/OFF the LED.
Can anyone share a schematic for the footswitch of the Studio Caliber?
What I tried to do was add a 680ohm resistor to the positive terminal of the LED, according to the diagram adapted from the MB Mk III, but does not switch between Rhythm and Lead, despite the LED switching ON and OFF. Apparently, I'm doing something wrong...
Your help is appreciated.
Thanks in advance.
Carlos
