Michael,
I have a few of your packs including your D-Pack, 69 Marshall, Tweed and one of the mixed packs. They all sound great , particularly the Dumble style amps like Ceriatone and Fuchs.
Which got me thinking, what other amp would I love to have a MBritt style profile pack of?
SOLDANO SLO!!!!
There are some SLO packs out there but they pretty much all focus on the metal side of things. Given that players like Clapton, Knopfler, Gary Moore and Warren Haynes all played SLO at some point (and Warren still does), it would be great to have an SLO pack that captures the creamier side of those monsters. If anyone can get those types of sounds from a Soldano its you
