Amplified wah-wah
Hi David,
I like how my wah-wah sounds without the mic. I can very clearly hear the tone change.
However I cannot accomplish a wah-wah with a mic. The tone difference is very very subtle if any even though I tried to adjust my pinch grip in different ways. It works a little bit better for me with the two thumbs up approach, but overall I like the pinch more and don't want to change my grip. It's uncomfortable to play the lower holes with two thumbs up.

Hello Ivan. It all gets down to how well, using whichever hold you prefer, you can capture the sound into your cup (how tight your cup is). So, experimenting over time (it took me about a year to achieve a good cup) is the process. Having the right thumb against your cheek is important, so make sure you're doing that. Keep at it, you'll get it.
