Hi,
On this profile you’ll find sound samples mainly from Spectors but also from other basses I have - current and past. 
The demos also focus on different pickups and preamps which I did try out. Hazlabs, EMG, Aguilar, Tonepump, Darkglass, SNC and BazCustom. Everything's mine, just doing it for fun.
