I've never used the Trickfish Bullhead, but have used a Bergantino Forte (purchased in 2019), with an assortment of Berg cabs and no complaints. The fact that the Forte is "neutral" is why I love it (I've heard them described as the Bose of amplification and can't disagree). I mostly use a couple of custom Jazz Basses, that all get different tones, so I can set the amp and let the bass (and my fingers) do all the work.
