I’m looking at adding an always on HPF under one of my boards. I am mainly looking at the micro thumpinator, Broughton always on HPF, and the FDeck HPF. If you have had these which did you prefer and why? I am leaning towards the Thumpinator at the moment...
The Thumpinator is fixed always-on. It will help protect your speakers to a degree but It won't help you dial in an acoustically challenging stage or venue or allow you to set the HPF near the tuning frequency of a ported cab.
I purchased the adjustable Broughton always-on. Tiny, easy to place, not an "effect" so no footswitch needed. Easily Cuts the boom and mud. Also allows you to turn up your bass tone control, more like a low mid.
I'm now considering an adjustable Bro-ton HPF/LPF because it does the same for the highs. It dials out the extra crispy clanky highs and allows you to smooth out your treble with your tone control. It has a boost control and footswitch if you need it.
Some effects users have the separate HPF and LPF and place them where they're most beneficial for certain types of effects.
I've read that first is your tuner, then a HFP/LPF in front of compressors and/or octave to cut the sub-sonic lows that can trigger frequency anomalies and for the, LPF, it cuts the fizz out of distortion pedals. Then an HPF is set at the end to make sure what is being sent to the amp is clean of any extraneous sub-sonic lows and may be set at a different level than the HPF/LPF because its purpose is to tame cabinet/stage/venue boom.
fdeck's is a HPF only, has a volume control, phase switch and can run on batteries too. Works for upright bass and electric bass.
Both units are popular and well thought of on TB.
