Received my Avatar B212 cab today. Paired it with my Genz Benz GBE600 amp. To say the least i'm not impressed! Could someone who plays through this amp help me with the settings! All i get is mud on the low end and if i turn up the mids and highs it's either to high or i get alot of hum. What am i doing wrong? I have a passive bass but when i imput on passive it hums excessively. The only thing i'm happy with is the volume this amp produces. It sure does kick! I have had a very long day so that could be some of my problem but i really expected more from this set up! I've gone from excited to depressed!!!!!
