I own a 1st generation (yellow button) H3000. It's a fun machine I should use more often.

I've wondered if the "magic sound" (ie: why people claim the plug-ins do not match the hardware) is in part due to signal latency & converter filtering interacting with dry signal in a manner that induces a sort of top end EQ phase smear. There is a syrupy quality to the sound that could be construed as sweet, this fingerprint factors heavily in my decision to use or not use the effect.

I really should explore more though, as it's been a while since I've fired it up.
First order of business would involve relocating it to a more immediately convenient location.
