I admit, I bought this wah because of the RHCP and John Frusciante. Ibanez promised to have transplanted the same circuitry of the old plastics WH-10 of the 80s into a tough metal enclosure. Well - they've done that almost. They added two 2n2 caps at the input and output buffers, the rest of it is the same. These two caps cause a bad, bad tone loss, espeacially of the heights but also remarkably of the level, both using the bypass and using the wah-effect. I am really no pedant regarding this issue, but it's that hearable, that you need e.g. a MXR Micro Amp at 10/11 o'clock to get the same level back (and still lose heights).
Solving the problem is so easy, that I blame Ibanez for it: just cut off these two caps, as they are just connected to the metal enclosure. Of course you lose the warrenty on it, and you could also use a true bypass looper. But that's really not handy for wahwahs as you might imagine. There's a huge amount of mods regarding this tone-loss-issue for a huge amount of money, installing a true-bypass etc. - you don't need it, if you cut the caps.
Though there is no real alternative wah on the market. You could spend 200$ on a wilson plus 50$ for shipping. Or you get a 30 year old plastic one, noone knows how long it will work. No other wah gets this rhcp-sound and that's why this is bought so frequently.
P.S.: After 2,5 years the wah-pot is scratching very much, and as cleaning the pot is just delaying the problem and there is no replacement part, I need a new wah.
Nearly everyone who's interested in the WH10 is a fan of John Frusciante/the Red Hot Chili Peppers. The Ibanez WH10 is the first choice wah of Mr. Frusciante and he used it since his beginnings in 1988 with the Red Hots. Now Ibanez brought us a reissue in a die-cast metal chassis - but sadly not everything went that well with the WH10V2.
The old WH10 was made of poor plastic so it had some cracks after some time and you were afraid to stomp on it - no one wants to break such an awesome pedal. The reissue version has a pretty good chassis out of metal with the look and feel of the vintage wah. You can dial in the depth of the effect on the left side (between 1 and 10) and you can switch between a guitar and a bass setting (the bass setting sounds also pretty awesome on guitar, almost like an envelope filter effect - try it!).
So, but what could be bad about the pedal then? It looks and feels like the old one, it even sounds like the vintage version - BUT: the on/off-switch isn't that great. I had to replace mine after 6 month 'cause it broke - on every WH10V2 I got (I have 3 at the moment). The other thing is...the boost. This HUGE volume boost. I have several vintage WH10s (black and gray) and I know that the gray version has also quite a boost to your signal but the V2 makes it unplayable with clean tones. It's really that loud, believe me. The last worst thing (and that's REALLY worse) is the bypass. If you want to use the pedal buy a true bypass looper to put the pedal in there. You will need it.
So - the WH10V2 is a real great pedal, with a great sound and feel. But you have to fix some things first to really enjoy it. The true bypass mod you find online is very useful, same goes for switching the on/off-switch. And maybe add an extra poti on the outside to control the volume boost. I'm very happy with my V2s now and won't miss them anymore - and my old vintage treasures are still in use: in my studio.
