Mine was something like this...
 

You cut your teeth on a champ?!! I hate you! ;)
 
I just remembered a gig we (my first or second band) had - I was 13 or 14 and it would have been my first ever gig actually, but we were cancelled at the last minute.
 
Officially, we were too loud. That's a polite way to put it. We SUCKED.
 
I think we had 3 songs - Love Bites by Priest, Circle of Tyrants by Celtic Frost, and an original...  
 
I'm forever thankful to my old music teacher for pulling the plug on us. I've had enough embarrassing moments in my life w/o that particular one - and the next of those embarrassing moments came soon enough, anyway. :P
 
Anyway, for the occasion, I'd borrowed an older friend's amp, head and cab. It was a "Garnet". I've never seen those anywhere else...
 
Not sure about the model, but, from memory, it looked a bit like this one...
 

I did say "something like" - it was a small, near-useless Fedner.  Then I moved up to something like this:

My first amp, in 1974, was a 40 watt FAL combo. All the worst elements of 1970s cheap solid state. Ultra-clean unless absolutely cranked when it was just unpleasant. No reverb but it did have tremolo and a 50Hz hum that could be used as a drone.

My second amp was a 1968/9 Marshall 50 watt Lead head which I got very cheaply indeed in 1979 because it was sounding a bit off and its original owner wanted rid of it because he wanted to buy a new-fangled HH "Valve Sound" transistor amps "because transistors are more reliable than valves". Five new valves and the Plexi was working fine....

My first proper amp was an HH VS Musician 'Valve Sound' tranny amp too. Back then we thought it was the future - I remember paying exactly £260 for it in Frank Hessy's shop in Liverpool aged 17 - That was a small fortune back then, probably equivalent to £1000 / $1600 now, it took me a year to save it up from a part time job. When I think back to the 'Valve Sound' it was in all honestly, an eardrum slicing cacophonous saw toothed racket, but somehow I managed to convince myself it was 'futuresound' for a couple of years until I finally heard it for what it was. The controls still had a cool green backlight though...

 
I started on a 10W 'practice' amp, which was absolute rubbish.
 
The casing was made of plastic, which says it all really
 
After that, my first 'real' amp (although in truth, it wasn't much better, just a bit louder) was one of these, a JHS C50R:

My first was some solid state 10w practice amp that was so bad, I for the life of me, can not even remember what it was. I guess I have blocked it from memory. I know that I had my first electric, months before I got my first amp.

Now the second amp I remember. An all tube Carvin 60w.

I've got one of those in storage in Colorado.
My first amp was a little Crate, '76-77 vintage. I bought it new, along with a Univox Hi Flyer(black w/natural maple neck). I was in college, and layaway was my best friend.
After several years of service, a co-worker talked me into leaving the amp at his place after a jam session. I never saw him again.
My second amp(I don't remember what it was) was stolen from our house a few years later, along with the Univox.
Thankfully, my trusty Ibanez LP, Gibson S-1, and Epiphone Genesis were in the basement, and I still have them.
The amp had some grounding issues, and it would bite you hard if you touched the power switch when you turned it on. It wasn't a particularly good amp, so I didn't really miss it. I still have to chuckle though, when I think of what my burglar felt when he turned it on. I figure he deserved that.
