high pass filter
I use his HPF-3 for electric bass and haven't heard of anything that does the same for less- I also think they are quite affordable for an original hand built design. I prefer it in theory to the Thumpinator because it allows tweakability of the filter. His Series 1 and 2 models are both significantly cheaper and will work for electric bass as well (though those were designed for upright bass), they just aren't as ideal (less steep roll-off on the filter and less ideal input headroom for the larger output if some electric basses). I used a Series 1 for a couple years before the Series 3 came out and it was still quite effective (though I do much prefer the more expensive Series 3 for the reasons mentioned above). Check the fDeck HPF thread in the amps forum for lots of testimonials!
