RE : Confused
Your choice is predicated on the guitar and since it's an acoustic you will need an amp that is really quite quiet with no noticeable noise .
To be sure of that when you test out an amp , just turn up the amp your checking on to it's max with out anything plugged in to it . If there is a noticeable hum or anything above a whisper it's not the one you want , it's that simple . Get the one that is the most silent .
As far as FX pedals , a nice chorus / delay and or reverb unit would work nicely .
It started for me with Twinkle Twinkle Little Star in 54 on a Blues Harp and progressed , then life .....some death ....Evolving as I went like a small rock in a stream rounding out as I went with the flow as I go through the white waters and waterfalls of life . Life has always been interesting to me
