Here is my first review of the TC BH800 and Ampeg SVT-112AV cabs:
I love the layout of the amp and its construction is superb, it feels like your holding a quality piece of gear.
I'm running my D-Huff Jazz bass directly into the amp with both cabs and the sound is fat, clear, and loud.
I'm mainly a rock/alternative type player and I was worried this amp would only get funk/slap tones since that is all I've seen in TC product videos. (Fix that TC) The amp has a wide range of tones from very warm and vintage fat to that modern slap or hi-fi thing.
I usually run my master volume full and bring up the gain as needed. This keeps everything tight and clean, which is what I like for the music I play.
With the master volume at full and the gain at noon the amp is loud, but not as loud as other amps I've had at that same volume i.e Mesa Big Block, Ashdown CTM100, Ampeg SVT-3Pro. Tonight I'm going to run the amp on an SVT-810 and see how powerful it is in a full band.
Things I'm not totally sold on yet are the tone prints. I uploaded an Octave TP which is pretty cool but sound really muddy and the volume level between the effect and the standard amp channel is drastic. I can't seem to even them out which is kind of annoying. The chorus settings are very clean and lush, the overdrives sound gritty and the fuzz is a monster. They have some new combination Tone Prints (Compression/Drive, Octave/Synth) some work great while others are so loud and have zero sweep from off to LOUD!!!
Built in tuner is handy and seems to be fast and accurate. I compare the tune to my TC Polytune to make sure the amp is getting it right.
I need to get a proper 5-string bass to run through the amp/cab setup to see how well it produces that low B-string. I have my 4 string jazz setup as a 5-string with a 125 B-string to a D string (no G) it sounds a bit loose when I hit that "B" hard. This might be the bass, I'll give a full report on it once I have an actual 5-string.
