Yes, I'm not sure what the interrealtion between the cabinet and code is though - I think a simple cabinet delay line + your IIR filter would be a good place to start. > just tried it, indeed it does. what i like especially is that > it sounds quite 'juicy' like good distortion is supposed to. > the attack phase is slightly better than with my previous > setup, though there's still some auto-wah. still with the I've fixed the wah noise in the second one I posted, it was due to a combination of things (lack of inverters, excessive valve settings, lack of lowcut). > >I'm having a problem than when the input is 0, the output is infinite.

I think it was a reaction betwen the dc offset filters.
