Is there a schem for adding a Power Amp Input to a BF/SF Bassman.?
I guess I would want to go into the PI...but I am not sure how to set up the switching...to separate the Bassman Preamp from the incoming preamp to Power Amp connection...if you know what I am trying to say.
Thank You

Re: Power Amp In
Off, the top of my head, I would think you could do it like an effect return. I troubleshoot amps with an effect loop by using an external preamp out into the effect return, bypassing the amps preamp section as a basic divide and conquer strategy.
Re: Power Amp In
This is how I do it. Also works as a passive effects loop. Just be sure to put the jacks before the input cap for the PI.

Re: Power Amp In
What if you just wanted a Single In for the Power Amp.?
Could you do that with a TRS Jack.?
Somehow Ground/Defeat the preamp signal, and allow an outside preamp to feed into the Power Amp, but it would allow the Bassman to function normally when not in use.?

Re: Power Amp In
Then don't install the preamp out jack. You don't need a two circuit TRS jack. Just a simple switchcraft 12A (single circuit with switch) will do. The preamp will be disconnected from the PI when you insert a plug into the power amp input jack. No need to actually ground the internal preamp.What if you just wanted a Single In for the Power Amp.?

OK, that is where I went wrong, it (preamp) can just sit idle, and disconnected from the output.sluckey wrote:Then don't install the preamp out jack. You don't need a two circuit TRS jack.
