Mail a leadsheet and an mp3 to moc.l1544518382iamg@1544518382gnidn1544518382ivsda1544518382m1544518382
If I think I can contribute something I’ll send the mp3 back with added bass. No charge.. 🙂
If you want to use it for commercial reasons I’ll send you the separate basstrack as 24 bit wav or aiff file.
Not for free – but not that expensive either 🙂
