Simply the best pedal platform 'amp sim' pedal on the market. Being analogue it takes overdrive pedals really well and they sound just like they should out of an amplifier. It has tube amp and speaker simulation and no cab SIM which is important - the sound coming out of the pa is like a closed mic'd guitar cab, additional cab SIM like on some digital modellers sound fine into a DAW but weird through a pa as you have a cab SIM coming out of a cab. I've tried the Strymon Iridium and the Walrus ACS-1 - the Iridium is absolute junk and makes gain pedal sound like trash. The Walrus was better but still not a patch on the Paradriver. Being a parametric eq you have the ability to 'tune' your sound perfectly to your PA. A brilliant but often overlooked amp sim pedal.
