Hello, I just have sold my WT-300 Eden head in a quest for a louder head and I was pretty much set to go for ABM 500. I even A/B ed them in store and liked ABM sound over WT so much.. first word that come to my mind was 'wider'.. But today i have found the time limited offer of new EBS Fafner for discounted price, still slightly higher than ABM, but not much more. It is in another city so i cannot compare them directly, but I have heard it some time ago and liked it. I play mostly funk, some slap, but mostly fingerstyle fat grooves, think Bootsy, etc. I play jazz bass with DiMarzios J and Schroeder 1210 cabinet. On ABM I liked warmth and fatness, but I think that Fafner might have 'juicier' bass and low mids. On the other hand EBS might lack tubeness of the ABM.. What would you choose?
