Bulldog Cabinet Simulator

I designed this for a upcoming project. My objectives were: keep it simple, low part count, common value components, for line level input and output. Oh and sound good Here's the schematic:

Bypass switching etc. isn't shown or needed depending on your application. Just one control 'Blend'. It blends between the straight signal and the cab sim. Here's a frequency plot to illustrate(Purple - Unaffected signal, Blue - Blend at 50%, Red - Fully affected):




Possible Mods

Volume - This should be easy to figure out ;). You could also not use the blend pot

Dual Power Supply - Just tie VREF to ground and -Vcc of the op amps to the negative supply.

Resonant Bass Boost - Change R4 to a different value or a pot. 33k will mostly flatten it. You don't want it lower than 6.8k or it'll start cutting bass. If you want to use a pot I'd use 25k in series with a 6.8k resistor. For a switch I'd just switch between 10k and 33k.

Other possible mods - you could totally redo the filters for one send me a email if you come up with anything interesting =).
