9 4 3Actions As the Achievement Detail suggests, just play through the career with any instrument on any difficulty once. This can be simply doing the beginner mic cheat and sitting back listening to the soundtrak or just straight up playing the game yourselfShowing all 3 comments. Leave a comment. Does it matter if you change instruments during your playthrough? like i do Guitar / Bass and sometimes Drumming as well.Posted by Zavistic on 25 Oct 10 at 04:37 im not sure i just did it with the Mic and sat back, i dont think it would affect it if you switched up the instruments, if you try it come back and post what happened, sorry for the late replyPosted by PIMOS BIG WILLY on 17 Nov 10 at 19:34 Confirmed that you can unlock this Achievement even if you switch instruments through your Career playthrough. I played mostly guitar, but would switch to Bass when the challenge called for it, and the Achievement still unlocked at the end.Posted by Vermin360 on 15 Jun 11 at 13:07 Leave a comment
