Unfortunately for me, they did not reply to my message about that. Although perhaps that is unfortunate for them, as I'd have bought two if they could have told me they work and are actually just missing the shafts. Once you pop the top cover, you can still adjust them. However, I am OCD and that would kill me. Not to mention I've never seen those for sale so not sure what four shafts & knobs would run a fella. Probably cheaper to buy a complete amp.
