Does it all

Playing for over 40 years I look at my tools as just that, tools. This instrument with the preset EQ settings on the 5-way switch, lets the working bass player go from thump to funk in no time. All the sounds are usable. The electronics are quiet and the body and neck fit me perfect. The body is light and balanced standing or sitting. The neck is unfinished and fast,and two octaves. the hardware is good. My playing styles are from Jazz , R&B to rock and country. I own eight bass's for that reason setup for different styles. This one can cover it all. also at this price point it is a awesome value. As always Sweetwater delivered fast and undamaged. The setup was also playable right out of the box.

I am not a very good bass player as I mainly play guitar. I had a hard time finding a bass that was as comfortable and playable as my fender precision bass but this bass is awesome. I wanted a bass with active pickups the eq switch is awesome very comfortable body and neck. I learned don't buy a guitar just because it looks cool get one you can enjoy playing and this one is aces on every detail a joy to play
Music background: I play in the comfort of my home for my enjoyment

Condition of product

The Yamaha TBX304 4- string bass is an absolutely wonderful bass guitar.Upon arival tho, the bass was grossly under set up with SUPER high action and buzz throughout the instrument.I'm used to impecable service and awesome product delivery of items in the past which suprised me comming thru Sweetwater.Not only was the bass not set up and the truss rod was freely moving and unattached to the body with SUPER high action, there were several knicks and scratches on the neck and edge of the fretboard.It clearly was a prior return from another customer.After spending money on a guitar tech to address the issues(who said it was one of the longest set ups he has ever done), the bass was impecable and plays like a bass much more expensive.Overall, the assistance and help resolving this issue was incredable and could not of been handled better.I still highly recomend Sweetwater for their great products and wonderful customer service, and love the products they sell.
