1983 @13 years old, give or take a few years. My brother played both bass and guitar. While he was out playing guitar his bass was left in his room so I snuck in to play it. It was a Gibson Thunderbird with horrible frett buzz. The first song I can remember focussing on was Metallica Ride the Lightening. Terrible idea, BTW, but that's how I started getting my chops (rhythm came later). I was into Queensryche, Racer X, Malmsteen, Helloween, King Diamond. My brother later worked at a music store and sold me my first bass, a Hondo 4 string with a tremolo. I broke many, many strings on that bass. I went to college with it and later got an Aria Pro II SB Elite II, same as Rudy Sarzo in the Still of the Night Video. I later went through a number of Ibanez basses, and some off brands (headway...). I stopped buying basses when I got my Modulus Quantum 5 sweet spot turbo. ... Well, almost stopped. Got into a band that was gigging a lot and decided I needed another, so I picked up another Quantum sweet spot turbo but with slightly different electronics. Some time during all the gigging we opened for Quiet Riot and I had Rudy sign my Aria Pro. My first bass rig was a GK mb series combo. I played it through an acoustic 4x12. Later I went all-in on Hartke - 7000 head, 2 4x10's and a 2x15. The 2x15 after i had destroyed two 1x15's. Had that for years and years. I now use a Mesa Impulse 600 on top of a powerhouse 1000, assorted effects and a GK 700rb 2x10 combo for smaller scenarios. Currently transitioning from rackmount gear to a pedal board.
