Pickup suggestion Martin 000-28vs

[Seriesnuns]

I’m looking at adding a pickup into my 000.

Mainly playing for small gatherings and non PA event.

I’m looking at a Schertler Jam for amp to do guitar and vocals

I want to get a K and K pure mini, do you think it is worth it to go head and k invest in the Trinity system or just the single pure mini?

Thanks!
