express - k60 - concorde

[castor]

Hi to everyone.
Some months ago I compeltely modded my express clone to similar mk pre.. i like it but after some months I came back to express standard and I love it (distorsion sounds.. clear sounds... touch... everything is fantastic.. and I can have even the new knopfler's low distorted round sound..)

Now the question: I listened many times to komet clips in their site but I could not hear very well the difference between the k60 and the concorde.
power is not so important... can someone that played both 3 (express - k60 and concorde) explain me the difference in tone and overall sound?

I lestened only live a k60 (knopfler's one modded by Ken) but through the power amps of the show and never a concorde
