I normally use these strings on my Warwick fretless Streamer with drop A tuning, and they're a bunch of monsters. Gnarly, punchy, bright, warm, everything a drop tuned bass needs.
However, I've previous used these strings with my fretted Warwick Corvette, and I did not like the results. The thickness of the B string and the standard tuning with my fretted Warwick just didn't go together well, and it took a lot of tone out of the strings and the instrument.
I use these with fretless Warwick Streamer, and Darkglass B7K overdrive pedal. This combination is an earthquake maker, and I recommend it to any bass players who need aggressive sounds.
