I turned the bass off and the poppin P's stopped. Maybe the vocal harmonizer when singing low notes affects my home stereo system more than it affects the keyboard amp.
If I can be patient and wait until I sell some of my bricklaying equipment that I don't need anymore (the Brick business in Colorado sucks anyway. All stucco projects now no brick)I can afford the Mackies. Or if my patience gives out I may go with the Carvin AG100. Boy life itself sucks sometimes.
thanks for your help,
Boo
