Well now, this, IMHO, is a rabbit hole waiting to go everywhere and as deep as you want to go
Lets start with vocals. Me personally,. would have a couple voice enhancers. Auto tune is great, but maybe one if the ones with harmony function. all kinds of good ones out. I have a TC Electronics Mic Mechanic 2. then there are the harmony machines. It just depends on what you want to hear in the speakers. https://www.sweetwater.com/store/search … ects+pedal
Acoustic effects: well there is a great multi unit for that. or maybe pick up at the minimum, compressor / sustainer, EQ (the Danelectro fish and chips is very good and affordable), then the rest is up to you really. However, if your amp has a EQ then you can drop the pedal. I have my boards set up for both guitars but this is what I run with acoustic.
Berhinger ADI 21 acoustic driver w/ DI > Compressor/sustainer (old Yamaha stomp) > EQ > Delay (or 2 LOL) > then add some color. chorus is a must, I like flange and phase. then I run to a older digitech 350. this just gives you easy options for all kinds of stuf lol. so its up to you. if you want to go lite, then its top 3 or 4. ( omit if amp had good eq) EQ , compressor / sustaintainer, chorus and delay. Or you can do the ADI to chorus and delay.
hope this helps.
