alright, I've been experimenting with using an acoustic guitar with Rocksmith and want to chime in for those that were curious on using an acoustic. My guitar is a regular acoustic with no built-in pickup. I'm only a beginner so please excuse me if I use incorrect terminology. I did lessons a zillion years ago but hadn't touched a guitar since and it all disappeared.
I didn't want to drill holes for a pickup into the guitar so I got a magnetic soundhole pickup. I read that this kind of pickup is perfect for some one who is looking to plug in with a minimal investment and doesn't want anything to be permanently installed.
I first tried a cheap one called the KQ-1A pickup. It was $12 at Amazon.
Looked great. But I had a hard time passing the setup as Rocksmith kept saying to turn up the volume of the guitar which was of course impossible with this pickup. I thought about getting a pre-amp or using an old karaoke machine we had but decided to get a different pickup because more equipment also means more variables to the equation to diagnose in the case it didn't work.
So I got the Seymour Duncan Woody SA-3XL Adjustable Pole Pieces Soundhole Pickup. It has a dual coil setup to eliminate hum which intrigued me (and it's reasonably priced as well at $60 at Amazon)
So I load up Rocksmith again and while the setup is much easier than the other cheaper pickup, I had to strum louder than I thought I should have to strum. I'm a beginner so I don't know exactly how hard you're supposed to strum.
Okay, normally, the Rocksmith cable is over 11 feet long and supposed to plug directly to your electric guitar's pickup hole. The pickup cable is 14 feet long so that's over 25 feet in length. Maybe that's too long. I used a stereo coupler to connect the 2 cables since both cables have a male end:
I later thought maybe it'd be better to get a mono coupler for better performance and one is coming in the mail.
Anyway, I go to play for the first time, tuning, riff repeater, guitarcade, etc. And I just felt like I had to strum awfully hard. So I thought I'd be returning the pickup and getting a cheap electric guitar (but I love my acoustic!).
Then the next day, I went back and tried it again. Plugged in the guitar again. This time it played perfectly in Rocksmith! I didn't have to strum hard. It sounded good. I was doing okay.
I was still having trouble with the frets toward the soundhole. for example, in the ducks game, when it asked me to do 11, when I strummed, it would sometimes register as 12. Would an electric help with that?
Anyway, I started thinking, what's the difference between yesterday and today? Is it that inconsistent? Hopefully the mono 6.35mm to 6.35 mm coupler will help a little. I know I did improve the way I pinched the string against the fret so maybe that's the reason.
I think I can totally survive with this setup. I still might get an electric so that I can play in silence (the whole house can hear me playing with my acoustic). I think I'll be keeping this pickup because it seems like a quality pickup and down the line if I wanted to plug into an amp, I can with this.
But now the electric is on my radar purely for learning purposes. I saw a Jay Turser 300 series guitar for $100. If anyone has an opinion on a cheap one, let me know. I just want to learn. No fancy sounds. I plan on going back to the acoustic for the bulk of my playing when outside of learning. The cheap ones on Craigslist were really beat up.
But yeah, if you're curious about using an acoustic, here's my anecdote.
