East and Lusithand filter preamps: anyone compared them?

[franzbassist]

I’m thinking of dropping a filter-based system into my fretless and was wondering if anyone has compared the above two preamps?  If so, I'd love to hear your thoughts!

Can’t remember but @funkle has a great thread Here on building a Wal’ish bass where he tries various pickups and preamps in pursuit of the Wal sound. There are also a couple of other Wal’alike builds in the Build Diaries section with at least one using the Lusithand pre. I have an early Overwater original series 5 string that has a filter based preamp and I think John East built the preamps for Overwater, but I am sure his newer designs will be more advanced.
