Solid State Guitar Amp Forum | DIY Guitar Amplifiers

hey folks , i just came by a tutorial about digital filtering using DSP implementation
its really a cure for killing the phase shifts with analog filters,but the circuit and programing would be much harder
its a case of not using a microcontroller but you have to go for a DSP processor for real-time application

thought i'd share it with anybody interested in the digital domain,
it also has a lot of examples and it explains how you can implement these filters using Matlab.
