Early 70's Equalizer with reverb box!

[Mike62Jazz]

I've got a "no name" EQ with reverb. It has no markings at all anywhere I can find as to Manufacturer. It does have an O.C. Electronics folded line reverb tank in it. Most of the caps are Nichicon. There is a mix of carbon comp and carbon film resistors.
Anybody recognize this unit? I've got gut shots if it helps.

I'll add a couple more pics!

Those reverb tanks sound like ass. Take DCR measurements and swap in an Accutronics that has the same coils. Night and day improvement....

It looks vaguely Japanese construction wise.
