i have been a fiver most of my life- i got a Tobias 5 back in '82 and never looked back. Recently, i switched to 6- it was a tough change, but i was feeling like i had it under control. Tonight i had to do a gig with no rehearsal and found myself having to play very fast bebop tempos and latin and funk charts. I even had a couple of solos. I played the MTD635 the first set. I found myself not relaxing and not feeling like i was deep enough in the pocket. For the second set, i decided to go to an R bass 5 i currently have. It was miles easier! it came back and i was able to handle the music with much more ease. Now, THATS got me thinking. Am i sacrificing technique and fluidity for the sake of playing a 6? If i am, isnt that wrong? Now i find myself with a beatiful MTD635 and a gorgeous Roscoe 6 in the making. but the 5 was so much easier! i know i had to sound better on it. how do you guys gofrom 4 to 5 to 6 with no problems?? should i go back to 5?
