Someone who is very knowledgeable about guitars and amps recently informed me that, when playing out of an amp, to not use any of the amp sims with the B3.
That's not entirely true. Granted, using an amp sim thru an amp is like taking an amp's voice and running it thru another amp's voice.
But, think of that amp sim like another effect. If running the fliptop patch into your SWR gives you the tone you want/like, then use it.
IMO, the some of the amp sims with their gain high, provide better overdrive than the dedicated distortion effects.
