I have been getting a bit confused with mine, as every amp shows up in the flow diagram as an AIRD preamp. And a lot of them feel completely dead. Now I know where to focus my efforts. Also found that my notes were just dying until I discovered that the guitar input level had to be cranked right up. Getting a lot more mileage out of it now.
Has anyone had much joy getting a usable wah out of it with a high-gain setting? I'm after that elusive Brian Robertson (Thin Lizzy) wah, and can't get close. They only seem to sound half decent with a clean rig.
