If you are building the HRM BluesMaster 100, the wiring diagram on the layout drawing is wrong for the Deep Switch.  The top 2 contacts and components need to be flipped with the bottom two contacts and components on the DPDT switch to get it to engage in the up position.

my BM50 was factory built and does this too:

Deep: On is down
Mid: On is Up

hmm a bit annoying. I can see this cannot be fixed without professional quality soldering, beyond my skill level

Same here with my OTS... pity you can't simply rotate the switch..!

It is a nice effect though, I use it a lot.

Yes it is a bit tricky.  You have to take the resistors attached to the top two contacts and move them to the bottom 2 contacts.  Vice versa for the resistors and cap on the bottom two contacts.  Those get moved to the top two contacts.  Once you have a tech do that the switch will work in the up position.

I presume from the pictures posted that the current (October 19 2010) layout for the BM 50w is also wrong. I hope this is the case; as I just wired my BM kit deep switch upside down on purpose. I hope it works right!
