3PDT in a MIT BOSS - Update

[SM]

It was no problem for me converting my MIJ CE2 to TBP using a “darker blue” 3PDT (as previously described).
Mike (Analoge Mike) tried the same concept in a MIT (Taiwan) with another brand? of 3PDT and reported that the mod didn’t work.
Unfortunately, that was correct. “Unfortunately” because to make a 3PDT/TBP mod “road worthy” with the “lighter blue” switch in a MIT BOSS (in my case a DS1) some more work is required.
Most of you reading this will not do the mod â€" but for you who wants to know â€" this is how I did to my DS1 (great pedal!). It works perfectly well (pic OK function).
Please excuse my sloppy English â€" this is not my area of expertise.

1. Remove the shaft and shorten it 2-3mm, shorten the pole 2-3mm (NOT more then 3mm!). Put it all together again and secure the shaft to the body (you could ad some cyanoacrylate (Super Glue) here, (pic a-e).
2. Install the 3PDT. Use 1 white nylon whisker underneath and 1 above. This gives a very good fixation and enough space for the board (pic f-l). The 3PDT is wired as usual (including LED).
3. You have to do the afore mentioned “Always On” mod (pic n-p). In “pic n” both FET’s are removed. In “pic p” the jumper I needed for “Always ON” is shown. This is probably true for other BOSS effects - although on my CE2 I just removed the FET’s with the same result (without jumper).
4. You may have to remove the rubber ring (pic m).
5. FYI there are differences in the MIJ box/casing compared to the MIT. Plus other differences (pic 1-3). Maybe that's the reason for the easy installation int the old CE2.

When doing it this way there is space enough for the board.
The switching works perfectly.
With the right tools this additional work does not require more than 5 minutes extra â€" without proper tooling it will be some more work… To much for most  :?:

Now - I hope this description holds what it promises. ANY feedback is appreciated!

Very cool! After using thousands of those 3PDT switches that is the first time I have seen inside one.

If you can mod those switches in 5 minutes, consider this a job offer  :-)

Have fun and thanks for the post!

yes ! the pictures are very cool. never thought anyone would think of disassembling a 3pdt and then cutting it shorter and reassembling it.

greatjob I definately don't have the tools to do this. I tried using a normal jacksaw to saw a screw before. in the end the part that has just been cut off had its thread damaged, hence it became useless.
