I just recevied my new EBS HD350 head and an EBS 210 cabinet plus an EBS BassIQ envelope filter, and I must say that I'm most satisfied with the sound of the gear. However, there is one thing that bothers me. The noise. With volume and gain at noon, the noise is more than I expected, and with volume past 12 o'clock and gain at noon the noise is much more audible than I had expected... If there's any other HD350 users here, what's your experience with it? Is a certain amount of hum and hiss something that you have to live with? Thank you!
