For anyone out there in googleland who has a chance to purchase either of these basses, this is for you. My experience with these basses began when I decided it was time for a 5 string Fender P. I bought one from a store that has a 30 day money back trial policy. I found that the B string didn't measure up to what I was looking for. I posted a thread asking for help in finding that P bass sound in a 5er and one of the suggestions was the Yammy BB1025X (X = PG). I returned the Fender, the owner checked to see what they had that might fit the bill. Nothing in house but a 2025X in Toronto that he would have to order. The shipping charge and the week's rental would be passed on to me if I decided to purchase it, otherwise, I'd just be out the rental. I checked one of their other stores in town along with a couple of competitors and found the only one available recommended by TBers was the 1025. I bought it, played it, loved it, and called the other store to go ahead and order the 2025 which I rented and have been countlessly swapping out with the 1025 comparing it with the 1025 to see if it is worth the added price. The difference (both used) is $780. New, the difference would be $1800 (assuming the max price I saw it listed for @$2800 - I did see them as low as $2500. The 1025 is pretty much around $1000 Cdn.) Aesthetically, they both needed time for me to get to like them, but I do now. The 1025 is tobacco burst, the other black. The only 4 differences visually other than color is the 2025 has a small plate around the input jack, the fretboard is cut at a 45 degree angle from the nut allowing the strings to stretch without interference from the top of the board to the peg (the 1025 has maybe 1/8 - 1/4" from the nut to the cut), and the tuning posts are smaller. The neck on the 2025 is darker than the 1025, probably due to the treatments that it undergoes which I'll briefly describe in a bit. The 2025 is made in Japan, the 1025, Indonesia. Soundwise, the 2025 has more punch with the split pup soloed, and more growl with both P and J pups together. The bridge J pup soloed is brighter on the 2025. These 2 short sentences took hours of cycling back and forth on both instruments, and I found the differences to be very slight. The big difference in price could be accounted to R & D that Yamaha invested in the methods they use to replicate an aged bass. Briefly, one used pressure/temp./humidity to molecularly alter the body wood so it's the same as a "vintage" bass. (I read that the supposed difference is only 15 years!). The other is to vibrate the instrument at different frequencies to replicate the vibration and consequent settling in of an instrument that had been played for a period of time (presumably 15 years also). Being as there is so little else that differentiates the 2 basses, this has to account for that huge $ difference. I'm 98% sure I won't do the deal. Firstly, because the sound difference I'm hearing doesn't justify the large difference in price. The 2nd reason occurred last night when I practiced with some classic rock guys. I realized that in the mix, those slight differences won't make much (if any) difference overall. Yamaha might have cut their own throat with the 2025 by making the 1025 such a fine instrument. It punches through just fine, and with tonal adjustments on either the guitar or amp, the difference in sound will be slight, if any.
