Trace Elliot commando 15 help.

[Louisss8sss]

I have had this amp for some time as it was passed on from a friend and have grown to love it but haven’t quite worked out what the little red knob on the back does. Does anyone know my guess is that it is a limiter of some sort?

I've never seen that before - looks like an addition / modification to me..

[AndyTravis]

Yeah, my Commando 15 didn’t have that 😉

Is that a Heft Control?

Yep, this! Ha! 😀

 

To the O/P,  would you be willing to pop the chassis out and take a pic? It may be DFA control.. 

[RandomBass]

Without looking at the schematics, it could be the bias trim control for the flux capacitor.

[MoonBassAlpha]

My guess would be it's a level control for the line out.

3 words that, when put together, strike me with fear "trace elliot commando".

Never had a knob like that on mine though, red too, that's not very Trace!

yes, Trace didn't make many duds but this was one, had the misfortune to use one on a multi band gig, "Trace Elliot combo supplied" oh goody methinks
