This is a Warlock bass guitar, used by many famous domestic and international bassists in the 80s and 90s. It's a bass with a lot of personality. The manufacturer is unknown because there is no logo. You can create various sounds with the mini switches, but the front pickup is not working. I opened the cavity to investigate the cause, but the wiring was complicated and I couldn't figure it out. It looks like the switches have been recently replaced. There are changes in sound with each switch. There are no problems with the neck warping or frets, and there is no damage that would interfere with playing. Therefore, how about it for those who are okay with only the rear pickup, or those who can fix it themselves? Thank you.
