OK, this is an easy one. I have this usa made vox wah with no DC in. I was trying to date it, get some opinions from similar users and find out if there's any known issues but there's no much info available on Google. Any help will be appreciated. Thanks!
I use one. Tried a bunch of different wahs, and haven't found anything I like better. I had a simple mod done (found it online) to fatten it up and boost the volume slightly, added true bypass, and put in a FoxRox buffer. I power it with a battery and just place it on the ground next to my pedalboard. It sounds great. They made quite a few of them apparently (I bought my first one back in the 90s, actually), because I come across them for $50-70 pretty regularly.
