Hi Stanislaw,
Here's what I found out about your bass:
model name: Epic
model number: WLB5
top: Megaflame Walnut*
accent: Maple
body: Mahogany
neck: 5-piece Maple with 4 Walnut pinstripes
scale: 34 long
fingerboard: Ebony
pickups: MXY56
controls: Epic volume, pan, bass, treble, mono output
originally made for: Guitar Center
birthday: January 9, 1998**
*This is the only time I've seen Megaflame Walnut noted, it must be very pretty!
**Since the serial number is under the finish, it was stamped in 1998, even though the bass was finished a few days later in 1999
I sent you an email with some other details about replacing tuners if you like.
