I just came back from GC and I picked up a Yamaha TRBX304 to try out. I put that down and picked up a Ibanez SR400. I was actually impressed with the craftsmanship on the Yamaha. It definitely can put out every possible tone you can think of, plus you have a choice of running it in either active or passive modes. I also put the Ibanez and the Yamaha side by side and the neck with looks identical. I mention that because everyone seems to compliment the Ibanez necks as being thin and fast. I did not see a difference. Yamaha makes great piano's and acoustic guitars but my knowledge of their bass guitars is minimal at best, except for what I read in the reviews. Has anyone played this guitar before or have an opinion on Yamaha's bas guitars in the general sense and how it compares with others. Also, I have been looking at trying to find a difference between the Ibanez SR300 and 400 besides the higher price tag on the 400. I did a side by side specs. comparison and they seem to be identical. Same pickups, same number of pickups and same electronic controls. The only difference I see between them is the colors they come in. Do I have that correct or am I missing something. Thanks in advance.
