Well, you’re going to need a tuner pedal; all that hard, consistent strumming is bound to detune some of your strings after every couple of songs! Tuning by ear is pretty tough in club gigs, so it’s always handy to have a direct-signal going into your chain. Almost every guitarist I know uses the Boss TU-3, but the Korg PB01 works just as well and is cheaper! Boss and Korg are household brands. We’re just talking about a tuner pedal here, it doesn’t need to be high end. My trick is to put my tuner at the end of my effects chain, so I can mute all of my FX noise abruptly just by stepping on it once. It’s a lot of fun with powerful climactic endings.
Soundproofing is important because in order to get a polished recording, you need to get clean takes of your instrument and vocal performances, and remove any chance of unwanted noise making its way into the recording of these performances.
