How difficult is it to install the Emerald driver and Obsidian soundboard? I want to have these eventually, they're simply not in the budget.
So, let's say I purchase a stunt saber, would I later be able to install the driver/soundboard? Any and all advice is appreciated.
Yes, depending on your level of wiring/soldering skill you can later install the Emerald and Obsidian boards.
IF the saber you buy is big enough to hold them both, which not all of the sabers are, so keep that in mind. (<- VERY IMPORTANT)
IF you don't mind voiding the warranty.
IF you're comfortable doing A LOT of rewiring, and possibly (probably) upgrading the battery pack as well.
Is it more cost effective to get it all at once? In the long run, yes. In the short term, when you have a limited budget, maybe not.
Personally, I'd have US do it, simply because it's easier. Yes, it will cost more, but I'm paying for the ease of getting it done (i.e. I don't have to do it) and the knowledge that it will be done right (i.e. because I didn't cross the red and blue wires).
However, if you're set on doing it that way, and doing the upgrades yourself, this is the sub-forum you want to be in. I'm pretty sure every possible wiring diagram you'd need is here somewhere, and the people who frequent this sub-forum (Racona I'm looking at you) will almost certainly have the answers to any and all questions you may have.
