So I've had a Hartke head for a few years now, and while it's okay, especially for the price I got it for, there are some things I'm not quite satisfied with. Mostly in the way it handles strong attacks. I tend to dig in a bit when I play, and when I do, the amp tends to make a sort of clippy sound like I'm peaking or something. This tends to happen at any volume level, and happens a little bit when I play more gently; there's always a bit of click at the beginning of the note. While this may be an issue with the cab, or a repairable issue with the amp itself, I'm looking to upgrade anyway. What I'm looking for is a flexible, versatile head without too much "inescapable" color to it. I love the graphic EQ on the Hartke, and would be very reluctant to part with that feature. I also like the generally flat response and color of the amp, which allows me to sort of slide into whatever style I feel like without feeling like I'm mismatched. If it helps any, I'm playing a Jazz bass, and I tend to favor the sound with the neck pickup rolled off ever so slightly, and I favor a Geddy Lee Power Windows style bouncy punch kind of sound. While I don't need to get "The Perfect Amp for That Sound", I'm not looking for huge booming bass or snarly scooped mids. Something nice and even would be great. If there's anything I'm dissatisfied with tonally in the Hartke, it's that it can sometimes feel a bit muddy in the upper mids and highs, and while I don't want a bunch of clank (I get that enough from my Rotosounds), I'd appreciate clarity. I think I've gone on enough about the sound I'm looking for, and I'm sure there are a lot of amps that will fit the bill. I'm just looking for some suggestions of what to look into when I'm shopping around for a new amp. I've got a lot on my "to buy" list, so I'd appreciate something less spendy, so no gorgeous all-tube amps for me, as much as I'd like to go that route. Obviously the more money I can save the better, but I also don't want to compromise just to save some money. Let's say, I'd love it if I could keep it around $500 or below, and I don't want to pay much more than $700 at the maximum. I have no problem buying used either. This won't be an imminent purchase, as I've got some other things on my plate before I go replacing my current amp, but it's nice to have some ideas in mind as I'm keeping my eyes open for deals and whatnot. There are plenty of amps out there, and while most are serviceable, there's no point in spending money unless I like it better than what I already have. It's also possible that my cheap B410 Acoustic cab is to blame, in which case it may make more sense to simply upgrade to a nicer cab. If this is likely the case, let me know. It could be that the cheap speakers don't like being pushed to start moving. Thanks for hanging in there for my wordy post, and I hope you can give me some advice!
