Display MoreHi, So I tried to profile one of my amps for the first time today. It's a 1979 Marshall Jmp. I hooked everything up
(guitar--->kemper input-----kemper direct out(send) ---->amp input---->hotplate in---->hoplate line out---->Kemper return )
I then selected a similar marshall amp profile in the browser and started the profiling process. It was nothing near the reference amp. I redid it again and try to match the kemper and reference amp volumes. Nothing near reference... I did the refining process 3 times playing chords. Was not sounding near the reference amp. I could totally hear a major difference through headphones ( Ath-m50s )
I tried redoing the same process, but with '' cab off '' in the marshall profile to get the sound a little bit closer to the reference amp...Still was not close. The reference sound is bright and large sounding in the headphones, while the '' kemper '' sound is dull, darker and just not the same.
Am I doing something wrong ? Is it suppose to be that inaccurate when not using speakers ?
Is it because it automatically adds some kind of '' speaker simulation '' ?
Leave the Cab section on even when doing a direct profile.
We have had excellent results using power soaks as well as DI boxed with connected speaker.
Please post some comparison clips, so we can hear how close you have got.
Power soaks are actually not as authentic as DI with real speakers, since the powersoak usually uses a resistor only to mimic the impedance of the speaker, which is not enough.
The famous interactions between power amp and speaker are more complex than what a resistive power soak can do.
