Modified Marshall ftsw for BM 100HRM question

Post by roknroll »

If I am asking a question that has already been answered, forgive me or direct me to the right page, or both. :D If not, here goes. The schem by mdroberts1243 Rev 0.99 Dec 20, 2007, shows a modified Marshall 3 button footswitch. Referring to the modification, the schem seems to imply an added forth stomp switch? The schem shows different values for the LED resistors than is actually in the pedal?
Thanks in advance

Hi,
Sometimes it would be best if you can link to or post the schematic you are referring to.
There are a few so it would help.

I did a brief search and I think I know what you are referring to.

A question was asked if it was possible to be able to go from Clean/Boost to Overdrive/no Boost with one click of the switch.

With this simple mod (diode and SPST switch) you can go from clean to overdrive with boost in one click and you can separately engage PAB when you want to in clean for a clean boost.

Here is the thread.
