i know. I love Andy’s tone and playing.
I think he does that mainly for convenience though. In the past he ran separate rigs for clean and dirty. He has run JCM800 in the past and still uses some Marshalls on recordings (if I remember correctly). His live sound until a few years ago was a Mesa Stilleto (Mesa’s attempt at a classic JCM style tone) for lead with a Lonestar for clean. That required double the amps and double the cabs plus mic’ing both etc. Now he uses a single amp and pedals to try and get the same sound. I’m sure if touring costs for staff, setup times, shipping costs etc weren’t an issue he would probably still love to carry the double amp setup but in the modern touring economy costs and portability matter a lot.
My point is just that with the Kemper you don’t need to stick a pedal in front of a clean amp to recreate the sound of an iconic head - just use the iconic head because it is no less convenient.
fair point my friend the kemper is a great tool your bang on correct about all your info on andy timmons happy guitar journey
