Hutton Posted March 18, 2021 Share Posted March 18, 2021 I am trying to find out what class (a,ab, or d) my Mesa Boogie Walkabout (300w) amp is. I really don’t know how to tell. Can I also assume that the amps bigger brother the m-pulse 600 will be the same? Thanks. Quote Link to comment Share on other sites More sharing options...
Downunderwonder Posted March 18, 2021 Share Posted March 18, 2021 Pretty sure it's AB, one of the last of the breed for mainstream bass amplifiers. @agedhorseknows for sure. 1 Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted March 18, 2021 Share Posted March 18, 2021 It's not likely A, which you see in valve amps of no more than 20w. 1 Quote Link to comment Share on other sites More sharing options...
itu Posted March 18, 2021 Share Posted March 18, 2021 Have to ask, why is this of interest? 1 Quote Link to comment Share on other sites More sharing options...

chris_b Posted March 18, 2021 Share Posted March 18, 2021 It's tube driven mosfet circuitry according to the Mesa web site. I guess that means it's a tube preamp and SS power amp. Quote Link to comment Share on other sites More sharing options...
