What add-ons can I get on mt guitar other than a pedal?

For your whole rig? It's an endless discovery. So many different types and combinations of amps, preheads, cabinets. A whole library of pedals...from multieffects, to stomp boxes, to boutique. You could also get a looper, like the Boss Rc-30 or300. Gr 55 is nice. It makes a guitar a synth (you nneed to attach the Roland pickup). So basically you can play guitar, and make it sound like a piano, sax, flute, ect, ect. You could also get into recording and making videos onto youtube. All you need is a an audio interface, which you can either mic your amp or directly record it. There are tons more. In your guitar, you can add a killswitch if you want. You can get the infinite sustain. A capo. A guitar tuner...
