Re: Marshall JCM 2000 Rack Mount Pre-Amp - Usage Question
yes and no. DO NOT run the speaker out into the fender, youll blow everything up.
is this a jcm 2000 head? i dont remember them making a stand alone preamp.
you can run the preamp out on the marshall into the front of the fender but it may or may not work all that well. if you wanted to run the marshall into the power section of the fender that would probably work better but would require modification of the fender.
what are you trying to get?
