Here are the eight audio examples for hints 2 through 9 in John Fishell's article. (Why not nine? Because the first one is a mic placement tip and can't be represented by an audio example.)
The examples include:
2. Crown PZM30 Boundary Mic
3. Direct and Amp Blend
4. Half-cocked Wah
5. Doubling with Capo on 2nd Track
6. Concrete Stairwell
7. Acoustic Guitar pickup
8. Mackie 824 monitors as "speaker cabs"
9. Mackie 1202 preamp run into distortion
All of these tracks have been doubled.
