Birthday celebration part 2 (the CC H150 Goldtop was part 1). I've had the 633 Drive King for a few years now, and was intrigued when Cliff Brown at 633 brought out the Firefly, a 7 watt Class-A 1x10 combo. It's basically the Dragonfly with the overdrive circuit from the Drive King added. I ordered one in February and picked it up yesterday. It sounds very good...

The controls are Volume, Tone (with a pull switch to toggle between "Tweed" and "Blackface"), Drive, Level, Reverb and Power. The Drive switch and Cab-sim output re located underneath at the back, while Drive can also be activated with a footswitch. The range of tones available is pretty wide by judicious use of the volume, drive and power controls, from a sparkling clean to Santana-like sustain, all at reasonable volume levels.

Here's designer Cliff Brown putting the prototype through its paces...

Perfect combination, I'd imagine its glorious!

At first when I read this, I was thinking it was from the same Chinese budget guitar maker, Firefly, that's sold on Amazon.

This obviously is not the case.

Yes indeed, I have the first production model. Ian Beestin, a drummer friend of mine, goes way back with Cliff Brown - I think they were at school together. It was through Ian I got to know Cliff, when he was still at Blackstar and just about to set up 633. Ian was always saying that I should try one of his amps, so when I was able to try the Drive King prototype at a music shop demo I was convinced!

Here's a pic from April 2016 when I went down to Cliff's place to pick up the amp. I brought along my 1x12 cab, the Heritage H150 VSB and Paulman Tele to try it out.

nice picture, when I contacted 633Eng he demonstraed to be reliable and a very down-to-earth man
that amplifier is one of the best in the UK in my opinion
