How do you plug directly into amp? I was told by a very reputable amp builder it needs a load box. I am not familiar with it. And do you use guitar, or speaker cables?
I just went to the Frenzel website and there are options available for this preamp that includes the "add a power amp" option. With just a frontal picture its impossible to know if yours has the power amp option.
I would send them an email and ask Frenzel if there's a manual for yours available for download, and what options yours has.
Generally speaking true preamps use instrument cables to hook up to a power amp. Output from Power amps being attenuated use speaker cables.
The inputs are high impedance and the output is low impedance. This allows the preamp to work
as an effects amp between your guitar and the input jack of your amp....or in your amp's effects
loop. It will also drive studio mixers or PA amps. If you have never played through a tube
preamp.. you are in for a real treat. If you have, you are still in for a trip, because of the
combination of Type F smooth warm tones and Type M high-mid overdrive tones and other extras that have been added. It makes just about any tube amp sound better......and for you guys with
solid state amps who are craving that vintage tube sound, you can insert it in front of your solid
state amp and get that classic vintage custom sound of your own
