I am running a P bass -> ART Tube MP -> Behringer EP1500 -> LDS cab. The real problem is the Behringer, I have it maxed out and am not getting enough volume. I know I should replace it with a better power amp or get a second cab, but I am looking for a cheap solution since this rig is just used once a week for practice. I have the preamp running with over +30dB gain (gain and volume at 3:00). Any more gain and the pickup hum becomes very noticable when we stop playing. 1) Would a noise gate in front of the preamp solve the problem? Or is the pickup hum too low to trigger it? This is a fully shielded bass and is very quiet. It is only the high gain that is causing problems. 2) If a noise gate in front of the preamp won't work, are there any inexpensive line level noise gates. I want to spend $100 or less. 3) Will a Boss NS-2 work? I have heard people complain it does not do much for cutting guitar hum.
