Sorry to resurrect a dead thread. But I though I would share some information.
I really dig the Aguilar Octimizer, and have been using one for many years. I've recently picked up up the newer diecast aluminum enclosure version (V2?) as a backup, hoping (without actually checking) it would be a considerably smaller footprint, as the V1 board always looked to be able to fit into something like a 1590BB box, and V2 was spec'd to not have accommodations for internal 9v battery...
However, If you look at the dimensions of the new version, it's not a whole lot smaller than V1.
V2's PCB footprint looks to have been completely redone, and is now much larger (almost the entire footprint of the V2 enclosure). If I had to guess, the reason for this is cost savings (fewer PCB layers, larger footprint?) I can't think of any other reason why this would have grown in size so much.
(From what I understand KORG acquired Aguilar and has probably begun to implement cost-savings into much of their product line.)
Additionally, with the settings set exactly the same, the V1 and V2 sound a bit different side-by-side. Close enough to be adjusted to sound 95% like one another, but I thought that was odd.
On the upside, Aguilar has used epoxy goop in the past to hide a portion of their circuit, but not on the V2. So, this circuit could be reverse engineered much easier.
At a quick glance of the major components, V2 looks to be utilizing (3) 2262 op amps, (1) TL072 op amp, and (1) MC14013B flip−flop.
Obviously, there's are also many SMD capacitors, resistors, diodes, etc to make up the circuit too.
Would like to see this circuit reverse engineered one day, and/or have it offered in the same size as the DB 925 (Aguilar I'm looking at you...)
