At 15, I bought my first amp - it was an ancient FBT bass combo - 60W. That didn't last a week at rehearsal. It starting distorting like crazy. Got in massive debt with my mom and purchased a Trace Elliot head and 2 x 15 cabinet. Sounded great but it was a 2 man job to move that thing around (I'm only 5"6). But I played that rig for about 8 years.
Replaced the Trace Elliot Head with a GK400RB-II. Soon after I got a GK 4x10 (SBX) and got rid of the Trace Elliot rig.
I replaced the 4x10 with a 2x10 and soon after bought a GK MB500.
The GK 2x10 blew up and I got an identical model with Neo Drivers.
The GK MB500 and GK neo 2x10 is still the only rig I own but it almost never leaves the house as 95% of my gigs are with a pedalboard and IEMs and I couldn't be happier.
