Not tried the MXR but I've used a Hartke Bassattack pedal for years and liked it, wouldn't gig without it now. Despite all the knobs and buttons on my Trace amp I think I can get just that bit more out of it with the pedal up front. I've used both passive jazz and precision with it. I wouldn't recommend it if you are into a lot of fiddling on stage though, the position settings on the knobs are almost impossible to see on stage. A while back there was an anniversary edition of the pedal with clearer knobs that was available at a stupidly low price, wish I'd picked one up. They are not available any more but the regular black one is, gone up in price a bit over the years but still cheaper than the MXR.

You can buy new knobs online very cheaply - I had the same issue with visibility and got some black knobs with a big white stripe on to replace the chrome topped ones for a couple of quid.
