I have been playing bass less than a month. But I play saxophone and piano already and have a degree in music theory, so I am not a musical beginner, just a beginner to bass playing. I picked up an (post 2008 model) Ibanez SR706 and am really enjoying learning bass! It's made in Indonesia, but a nice playing bass in great condition. I was wondering if an older Japanese made TRB 6 II (ebay) would be considered an upgrade? I do tend to like the balanced Japanese approach in manufacturing and engineering -- cars, saxes, electronics. I really like the Ibanez, but have noticed an appreciation for things made in Japan, Western Europe, and USA. Would I (beginner player) feel a difference between the two? Is there any upgrade available in anything that would cost me less than $1000?
