Playing a little riff and trying out the functions on both pedals, as they both want to reduce noise in your signal, but have very different ways of going about it. We used a Fulltone OCD for overdrive, Vox AC30 amplifier, with a Gibson Les Paul 50s Tribute with P90 pickups, so the guitar would be nice and noisy. Shure sm57 on the front of the speaker and a Sennheiser Md421 on the back of the cab. Just playing a basic little riff, trying things out.. hopefully its helpful to you!
