I'm a "less is more" kinda guy with acoustic effects, but, that said, I do occasionally like to use some. Here's my current rig:
I rarely keep the Fishman Dual Parametric D.I. box in the chain any more, but I can put it back in if needed. These days its pretty much the polytune3 & Fishman ToneDEQ. The polytune3 also acts as a buffer for my K&K pickup'd guitars. The ToneDEQ has everything *I* want - Reverb/Chorus/Compressor/Volume Boost/DI/low cut filters - & several additional effects to mess with - Delay/Flanger/Tremelo/EQ.
Works for me!
