Searching for parts

I just found an Arc KS1000.1, without the bass knob. I didn't think this was going to be a problem, since I am more of a set it and forget it type, however..

The thing defaults to full-on bass, so I am wondering who sells replacement knobs, or if some of the other Zeff designs would share the same part?

Thanks

Wow, now I feel like an idiot; thought I had that avenue covered.

Thanks tons, guess it never hurts to ask.

btw, never guess where I actually found the amp...
