I don't have an circuit analysis to offer at this juncture, but I've not seen any gut shots of the Kongpressor on the Internet, so I thought I'd supply some. It looks like it might have originally been named Squash Comp in the design phase.

The clustered strips of resistors is unusual looking, to my eye, I haven't seen anything quite like it in the few dozen pedals I've opened up.

Hi Guys,
yesterday a frind of mine give me a Darkglass Duality to try.
I just opened it and shoot some pictures.
It is based on 4049UBE CMOS.
All Pots are 100kB except for the Level Pot which is 100kA.

unfortunately I cannot hold the pedal so I will start tracing the pedal from the photos. In the next few months I will have the opportunity to have the pedal back in my hands and check all the connections. If someone has the pedal and wants to help me, you can write to me in PM.

Just stumbled across this on the web. It appears to stabilize the effect of temperature on the transistors via a proprietary circuit . Any guesses as to what's going on here?

So, got one in and traced it.

Speaker sim out is similar to the Screamon Blues pedal

Here is the second installment of my bass amplifier series - the Ampeg SVT in 9v pedal friendly format.
Plug this pedal into any high wattage power amplifier and experience the Super Valve Technology sound without tubes :wink:
This design is based on the original Ampeg SVT but with the 5 frequency bands mid boost / cut rotary switch used in the later SLM MkII model.
I left the bass cut option in the ultra bass switch control out as well just as they did in the MkII :wink: However I modeled the...

Any idea what's going on inside this device?

Can I get the Dale resistor values? Thanks!
