Morley PBA-2 vs PWO vs CLW vs mark tremonti vs...

Hello everyone!!!

Well, I own a morley dual bass wah that I bought used at a very reasonable price and the sound is ok... I guess... I'm actually looking for more fuzz + wah "scream" à la Cliff Burton (since I'm in a metallica tribute band... and I love the sound!!!) and I was wondering if you guys know which model is closer that sound

I've read very good things about the tremonti on bass and the Pwo, but I haven't found any useful review about the classic wah so let me hear your opinions!

By the way if you know any other brand or model (I'm sure you do ) I'm all ears!!! But keep in mind that in Mexico we don't have many brands. I love the switchless design that the PBA-2 has but is not a must and I've tried the dunlop 105Q but didn't love it.

And one more thing, a vintage morley is not an option since they're very rare here and VERY expensive (and I mean it)

So thanks in advance for your help!!!!!
