I was just searching the wayback machine website for Trace Elliot history.
The 2001-2003 version of the site, hosted by Gibson, has the 12- and 7 band (AH1000-12, AH500-12, AH300-12 etc.), V-Type series and Commando combos. I tried to scrape everything I could but all the pdf's that used to be on there are sadly not available.
Now hitting the 2005-2008 website...
Edit: 2005-2008 is AH1000-12 with the ugly plastic green light rims. I never liked the look of those much although the cabs from that era look stunning.
So to get things historically in perspective:
Eighties: Mk II, Mk V. I have not seen any others.
Early nineties: Series 6 and Valve series (Hexa, Quatra, Twin).
Mid nineties: SMX, SMC, BLX combo. Kaman era. (bought the company in '92).
Early 2000's: 12 band series with Tube overdrive, harmonic emphasis circuit. Commando combos, V-Type series. Gibson era. (bought the company in '98).
2005-2008: 12 band series with the plastic looking front. AH1000-12 etc. Early Peavey era. (bought the company in '05).
2011-2015: URL changed from trace-elliot.co.uk to traceelliot.com. AH1200-12 etc. 2nd coming of the Peavey lineup.
Clive Button came into the picture from 1985, originally for the MP11 but his designs continued all the way up until the Gibson era.
I do not know if Clive had any part in the Gibson era amplifiers. His website says he worked with Trace Elliot on a freelance basis until 1997.
1997 is where I believe he started work on the Ashdown ABM amps, with Mark Gooday, innit?
