Boss pedals and circut boards

[Skater]

Looking to get a Boss Sd-1 to mod, what years have the large PCB boards? The ones with the diodes.

Thanks!

Hmm, they all have diodes, I think you are looking for the ones with thru hole parts?

According to Analogman it was sometime in 2018.

used to be people lusted after the mij ones, now its mit before surface mount

Now I'm curious if the OD-3 I have coming is SMT or thru-hole. Not that it really matters. I'm one that likes to know what the innards are.

Monte Allums has some good info on which boards work better and all kinds of other stuff like links to surface-mount, and through-hole soldering. You kinda have to search for it though.

Even with my old eyes and shaky hands, I've replaced an SMT op amp twice now in a girls electric violin because she put the battery in backwards. The chip was 4 mm x 5 mm. With care and diligence it can be done.

Probably a good idea to install a reverse polarity protection diode!

I recently opened up my LS-2. I bought it 2 years back brand new.

Was quite positively suprised to see it was all standard thru hole parts.

I thought they we're all SMT by now.

If I ever see her again, I will. I've always wondered why pedals and electronics don't do this anyway. I wouldn't think that a .7-volt drop would be that big of a deal. I'm talking about in series with the hot lead, rather than backwards in parallel with the battery. I've seen those before. The diode fries and then you still have to repair the pedal.

To answer the question, unfortunately the SD-1 doesn’t have an easy to ID change on the outside. The BD-2 and DS-1 have different power jacks you can identify.
