I've been on a Winery Dogs kick and was trying to think what other guys that play had rock use fender amps. I can only think of Richie Kotzen and Nuno. And I believe Sambora use one for a while. Who else does/has??
I use a Twin all the time.
Of course these days you can plug a killer boost pedal into a good clean Fender and have a roaring beast. Turn it off and have brilliant cleans.
I use a Bogner Red.
Joe Perry used to use Tone Masters, as did Lynch and Sambora...actually a lot of hard rockers used that model back in the 90's.
Rick Nielsen has basically always used Rivera-modded Fenders...Deluxe Reverbs IIRC.
Greg Howe used those red knob models back in the 80's.
Mike Ness from Social Distortion still uses a blackface Bassman head.
Warren DeMartini used a Super Champ for many of his early solos.
Curious if the OP was looking for guys "currently" using these amps. I can imagine many have used and/or tried a variety Fender's over the years. What about "current" rock players? I am sure some of these are more current, just asking...
