Erich Gruber, I am not doing gigs, but think at 45 watts would think be enough . Simple controls master bass, mid ,high & reverb, which is pretty responsive.  

Henriksen does a nice job, a lot of pro's seem to gravitate towards them these days.  I discovered DV Mark, they make a 8" & 12" went with the 12" thinking the 8"  be brighter than I wanted. 

Perfect, thank you

Jim, so are the lessons boilerplate, random, impromptu or by your knowledge?
