Oooh, where to start?
Around 1970, had a smallish Selmer valve combo. Took it to Swaziland, where it probably still is!
Didn't have an amp of my own again until I found one when clearing out an RAF camp in 1974, a home built 50W 2x12.
Next was a Selmer Treble 'n' Bass 50 combo, followed fairly swiftly by a Roost 1x15 folded horn fed by a Vox AC50 head. That was a great sounding rig!
The Vox was replaced by a solid state 120W head which I had until I gave up completely around 87/88.
Roll on 2003 and a fat redundancy cheque has me buying a Sting bass and an Ashdown Electric Blue 15-150 (UK-built!). Once I got seriously gigging, I added a Deep115 cab which made it a pretty good rig, although it had to work hard.
On that note, I went to Mansons looking for a Mag 300 115 combo to go with the Deep 115. Guy in the shop says, "Have a go through that, you won't believe how nice it sounds!" Well, the Mag was sounding nothing special, so why not?
Markbass CMD121H...my wife is not at all musical and even she said how lovely it sounded! Take my money! It woke up that Deep cab too...
Since then (2006), it's been MB amps all the way, either the combo and cabs (currently a Traveler 121H) or an LMIII and a Barefaced Super 15, now both sold.
So there we are...
