i've gone through more wahs than i can remember...but i'll try...tremonti, vai bad horsie 1, lynch, regular dunlop gcb95 stock and modded, area 51, vintage chrome morley power wah, dime wah, and a 95q...i think that's all of them. i loved the tones i could get from the dime but like you crabby i like switchless wahs much better. the same goes for the area 51, that thing rocked tone wise but i was so used to having switchless morelys at the time that i sold it. now i have a 95q on my board and am happy with it but it's not 100% perfect but of the switchless wahs i've tried (never used a silvermachine) it's my favorite one. the tremonti like you said was high pitched which i didn't like, i actually modded it to stop the sweep from going so bright and edgy but it still wasn't right for me. it just didn't talk enough with that deep vowel like voice you can get from other wahs which i like. the wow mode on the lynch was kinda cool for a while but it was a bit stale sounding in regular mode and nothing all that special. i was considering a rack wah (even though i don't have a rack) just so i could go switchless with tons of tonal options but i still haven't taken that leap since they aren't exactly cheap. i honestly have little hope for that kiko wah to be honest with you because all the morelys i've tried have been ok but just didn't talk like a classic cry baby or vox does they seem to cut more and just don't seem to have the sweep style i'm looking for. part of me wants to check out that hammett wah because it may have a cool voice but being that it's not switchless odds are it would only last on my board for a short time.
so i'm with you, they need to make a switchless wah with all the tonal options of the dime and i'd be happy.
