Got my Broughton Fliptop today, tried a good half hour. I compare it to the Xotic Bass BB and SolidGoldFX BetaV.
The Fliptop has a low gain subtle “hazy” overdrive that’s hard to completely dial out. Unsurprisingly it also depends on the strength of signal going into the pedal. Gain above noon doesn’t sound good, chokes out, but some might like the sound.
With Cabsim off there is a very pleasant coloured Beatle-ish rubbery articulation that reminds me of the Diamond Bass Comp EQ tone. Turning up the Cabsim brings in the HPF and LPF, with a resonant bump in the very low mids. This turns the tone dark, middle frequency forward, with a tight kick-in-the-chest low punch. The Broughton Resonant Filter Equalizer easily does this Cabsim effect, and more, highly recommended.
The Xotic Bass BB has a baked-in dark middy dirty tone. The dirt can’t really be dialled out and gets harsh at noon. Treble can always be turned up to brighten. There is always a good dry middy articulation. I run mine into the Xotic Bass RC booster which sort of clears things in its own special way.
The BetaV is more versatile. It can be a clean boost, the overdrive is more pleasant to me even at higher gain. The LPF switch can make it dark, and accentuate the mid-frequencies in one of the settings. Not quite as articulate as the BB, certainly not as percussive as the Fliptop. But the bass and treble eq can be adjusted to stand out in a mix. The Broughton RFE is helpful with the BetaV.
