I used many Wah Pedals...
Dunlop...JH-1, 535, 535Q, Dime Wah, GCB-95, ZW-45
Vox 847
Morley Bad Horsie
Budda Wah
Tech 21 Killer Wail Wah
Rocktron Blackcat Moan etc..
I like tough and wide range sound of wah.
So I like Dunlop Wah.
Vox is too vintage and small range.
Budda is very clean and modern sound...range is good..
but not enough at Hi-gain sound...
Morley is very modern sound...but too big...
To me...
Best Wah is ZW-45..
I like JH-1...but range is too short...so very difficult to control..
Zw-45 is very similar sound with JH-1..
and Wide Range...so very comfort to control...
Next is Tech 21 Wah...
It has 3 sounds...
1 is look like Vox...and 1 is Cry Baby..
1 is for Bass or 7 string...
Very easy to control...and sound is nice..
