Aria - DT-10 Dual Distortion

I still use this pedal and its sound has held up, even though it's not the sturdiest design. I like that one can pre-set a higher gain level for solos. I recall reading somewhere that the Aria DT-10 had a bit of cache because it used the same chip that is found in the Ibanez and Maxon distortion pedals from the 80's. Anyone here have more insight?

Did you open it up to see the chip? That would be a way to go...
If it says "JRC4558D", then you have the good one.

Nope. Mine has 2 chips: a TC4013BP/8419H and a TC4069UBP/8506HB. Is there anything that you can fill me in about this pedal?

Yes, those are inside too, but only for switching.
There is another 8-pin chip inside, a 4558D (and six FET´s 2SK30A-Y).
The audio-path consists of:
A Fet-buffer,
A Fet-amplifier stage,
A MXR Distortion+ opamp stage with diode clipper,
followed by an EH Big-Muff-Pi type tone-stack,
volume poti,
Fet-switching,
opamp output buffer.
Since this is a MXR Distortion+ style - as the name says - "Distortion" (and not Overdrive) it is not really important which 4558 exactly is inside.

Thanks! Any history behind this design that you know of, and are there any suggestions that you might have for applications?
