Assuming you are talking about Martin guitars the pickup you mention would
be the last system I'd use to amplify an HD 28 . The best pickup for the HD
28 and other Dreadnaught Martins is a Fishman Matrix II or if you can afford
it a Fishman rare earth magnetic pickup. Martins big dreads are designed to
drive the bass rythums in bluegrass music and need to be eq'd accordingly
for something like playing in church PA's . Both the player and the sound
person needs to have some experience in acoustic amplification to get a
good tone from any acoustic much less the difficult to amplify Martin Dreads

I find Martins sound best with Mahogany body and a red spruce top for sound
reinforced use and or recording purposes. There are many exceptions but most require a really good matched pickup and good sound engineering.

I'd suggest for worship go get yourself a dryer gutiar.
