I you are patient, a used Bassbone can be had for about $200. New or used, what you get at that price range is a unit that not only gives you the features you're looking for, but so much more. I consider it to be the nerve center of my rig. Half of the gigs I play are with 'provided' house amp rigs, and the BB has enough EQ firepower, plus the boost option, to get me through any situation. I love the fx loop, so I can use a few, or many stompboxes(depending on the gig)and just plug them in, and switch them in, as needed. Then everything can be DI'd to the PA, and amp, with the same sound. I use the 'one bass, switchable EQ' set up. Many times I do the EQ flat if the amp itself is sounding good, but I still have the option of the knob tone controls. The routing possibilities are well thought out, and I like that it doesn't have a particular 'sound'; that's what an amp is for. This just tweeks/sculpts the tone if needed. I do place a Markbass Compressore before it, but anything like fuzz/overdrive(plus all the other stuff like chorus and envelope follower, etc)are in the fx loop, easily bypassed. It's a cliche perhaps, but it's a Swiss Army knife, and way ahead of the other units mentioned.
