I had the tc bq500 which I assumed was the same as the bh range without the tone print. Although the tone of the amp was ok (although I did end up with a pre amp pedal in front of it), I just couldn’t get on with it at volume and especially in the mix of the band. It just felt wrong. It didn’t sound squashed, but it was like the signal was compressed and the notes didn’t have the same attack & they sustained for way too long.
perhaps I was out of headroom - although I’d rarely be past half way on the input and output volume.
I’d take an ABM over it any day.
I am beginning to think perhaps it was just the tc amp I didn’t like, rather than it was because it was class D though
