I fall under the category named " Gas ", especially in the last 5 years or so, since the new lightweight bass heads have come out. I tried just about every one ! But, I usually sell them here on TB if they don't do it for me. Right now I own 3 bass heads. My "Silver Bullet " head is a Carvin BX1500, which is the best bass head I have ever used ( so far ! ), a GK MB200 , mainly used as a backup/headphone amp, and a soon to be used MusicMan HD150 head, for a small Blues/Rockabilly project band starting the first of the new year. I have also gone the pre/power route for many years, trying many different bass preamps and the usual suspects as far as power amps go. It's a continuous thing with me, but, the BX1500 is gonna be my go to amp for a long time.
