Wah History: I first had a 105Q before upgrading to an EBS WahOne. However, I'd downsized to a Pedaltrain Mini and did try a Morley Maverick. I like a switchless wah for ease of use live. However, this wah was a low end suck and didn't come close to the EBS (or even 105Q).
Setup Tried with: Spector US NS2 > Genz Benz Streamliner 600 > Epifani PS410.
Pedalboard: Boss TU3 > EBS MultiComp > Plutoneium Bass Chi Wah Wah > Amptweaker TightDrive > EBS Tremolo
Band: My metal tribute band (we do 70's and 80's metal from Sabbath to Maiden) has been working on a side project for a bit now. All original, heavy, riff driven, but with a progressive bent as well. That was this band's practice. 2 guitarists with Marshall half stacks, drums, bass vox.
Review:
I loved the Bass Chi Wah Wah. First off, it is super tiny! I was concerned because my Pedaltrain Mini is modded to house power supply and X2 wireless underneath. This means it has oversized rubber feet and sits higher than standard. I was worried it would be uncomfortable or difficult to play the Chi Wah Wah since you just use your toes on the front. It turned out to be comfortable and not a problem.
Secondly, I found the controls really useful (especially level and gain). I was really able to dial it in where it stayed very fat and up in the mix in the loud rock band setting. In fact, it did this better than any Wah I've ever had. So often, I find bass effects get lost next to two Marshall half stacks.
I honestly didn't fiddle with the countour control much. I found a great sound (had it at about 11:00) and just went with it. We closed out practice with 2 old Sabbath tunes, so I'd played my other wah's on Into the Void and NIB countless times. I really thought this sounded the best.
I'll try to plug it up at home with my Mesa Walkabout and one of my Sadowskys to write a review from a different angle.
