Hey all!

Just got this unit in for some reviews. Nice sound

When I open her up there are 4 TL062 IC's but one "weird" F4580 IC....... what is that?

Will post pics later!

Thank you! Why would've they used all TL062 but kept the first 2 opamps in the signal line this one?

It kinda works......... filter is not lineair but quite OK. Love the clean blend.

Had no time for a full review.

i friend sent me his Lomenzo hyperdrive (and wants e to clone it in a smaller enclosure) but it has more parts than the schematic above. i built one according to the schematic above and while it works, it doesn't sound the same as the original.
