All my time as a bassist up to this point I have always had combo amps. So I am very in experienced with cabs and heads. So for my birthday I just got a Gallien Krueger Backline 4x10 BXL II cab. Im sooo excited to actually have a cab and head....but heres where you experienced people may help me. I want to know what some good heads are that would be just right for this cab. The cab is 4x10 with no horn or tweeter and is400 wt & 8 ohms. I really could use some help and would appreciate any advice from you guys! Thanks so much, Jacob
