So here's my story man. Overall: Very well thought out, well built, practical tool for the bass player.
read this thread? my review is #46 (same head)

Now as a head, its flexible to power any cab with it (alone to a gig using supplied cabinets - your bass(es) EQ already saved in the 3 memory slots, adjust for the room), and you can use it alone for practice with an mp3 player and 'phones (1/8" to RCA stereo cord is included). Its portable.
You can't go wrong with it. compare power and features with other heads in its price range: tuner (with mute), compression, and tubetone - sort of like getting 3 pedals with it. The Tweetertone on the front is another useful sound shaper - I find it works almost like a
mild 'presence' you'd get on a BDDI unit. Add the 3 memory saves function. Man, so useful. I use one for a '74 Ric 4001 (low gain pickups), a single coil P bass (hot-rodded direct to jack), and an ATK750ka (active). Distinct sounds with one click - AND useful for the different outputs that each instrument has, using the Gain Clipping light.
Its an impressive amp with lots of power, and real world useful features. 27 lbs is nothing really, it feels like quality. The black cabinet built around it adds protection and gives it a solid, serious look... more so than the little 'transistor radio' gadgets of some of the light-weight heads these days. The face is a deeper red than you see on TC's site - which I like more than the candy apple red as it appears on the site.
I've paired my new BH500 with an Avatar B410NEO-4. Shazaam! Full bass presence, over using volume, to be heard. Feeling the bass now that I've wanted. The B410NEO-4 sounds perfect powered with the BH500. Its a very deep sounding cabinet, so for the room this weekend more hi-mid, treble and tweetertone - no problem, it was ALL there.
This weekend I used it for the first gig. I offered my rig up for the backline also (3 bands). Its baptism of fire. The next band up had a friend of mine playing who is professional and far more experience than I (his rig is a head and 410 from Markbass). He liked it a lot and said "It really has
the stuff!". The real treat for me was to hear my rig from the audience: it had the feel and sound that I've always had in my head.
Very excited about this new set up. I'm a player who's never made my living from bass playing, and only been in a couple of gigging bands, but jam plenty, and Bass is a part of me. So having such affordable, well made, quality gear is important.
