I currently own a Hartke 3500 which I hate. Its making my life miserable. I've been considering buying a Sansamp bass driver to go with it or just selling it and buying a better amp. Problem is I'll only have the money from the Hartke and an extra $150 towards a new amp. I've looked at SWR and GK but they aren't much better. The only decent thing I've found is a used Eden. I like the warmth and smoothness of the Eden but it sounded a little thin. I'll be using it alot for a rock band and I don't know how it will work out. Will it be as loud as the Harke? Any advice is much appreciated. I really hate Hartke. Thanks.
