Other players seem to like this bass, here's what I gleened from the iternet "The Aria Pro II TSB-400 was the higher end of the Thor Sound models, this has two pickups which are massive split coils and this puts out a tremendous low end because of the p bass body design and rosewood fretboard, but you still can roll over the high end and get a lot of snap out of this bass".

The frets are in great shape and all of the electronics work and have been cleaned out. Cosmetically this is a great looking bass guitar, heavy but nonetheless, gorgeous to look at, hold and play. Of course there is some wear and tear and there's a small ding to the lower bout, just below the volume / tone controls on the edge.  I have shown this in the images supplied plus you can see how light the wear is across the instrument as a whole. While there are some dings and surface scratches it's absolutely nothing for a bass instrument that has been played and loved across 4 decades. 

So if you are a serious Japanese collector and want a very nice all original thumper here it is. If you have any questions at all please ask. Offers welcome but don't try to low-ball me, I'll leave it on the wall as a beautiful ornament rather then give it away!!
