Just a quick update - I borrowed an RCF monitor from a mate and it sounded good.
So it was a combination of errors. Whta I dd notice though is that some profiles sound similar to those through my cab and others totally different! In some cases better but in others worse...
I need to get some time with a PA and play...
Glad to hear you made progress V8. One thing I want to mention is that I have since upgraded to FW 2.7 and I have noticed the KPA even sounds better than it did before through the PA and also through my FRFR monitor. Some of the profiles I didn't particularly like now sound so much better with 2.7. Like me when I first hooked mine up I said this thing doesn't sound good at all then reading the manuals helped and found that settings needed to be changed. After that it got to the point that I could not quit playing and cost me many sleepless nights.
Yes, RCF is for sure a decent one.
And, just like with real amps, you'll like some profiles better than others.
This. After all profile is a rendering of a set amp, so you might happen to not like the sound or it might be thought for a guitar completely different from yours.
Some people like to tweak, others prefer to try other profiles

How a regular cab compares to FRFR speakers will vary a lot with tone and profiles. The frequency-response of your cab is probably anything but linear. A guitar-tone that carries a lot of frequencies your cabinet doesn't reproduce so well will sound very different compared to a FR cabinet. A tone where the dominant frequencies are reproduced equally well by your cabinet may sound almost identical to what it does from a FR-speaker. A tone dialled in for your cabinet is less likely to sound good from a FR speaker. If you dial in all tones with a cabinet you may find yourself required to put a microphone i front of the cab to get decent sound for recording or FOH-mixing. It is very hard to mix traditional cabs with FRFR-systems with the exception of those few virtual rigs that produce a tone which is a good match for the frequency-response of the cab. I.e. where the characteristics of your poweramp+cab combination match the characteristics of the chosen cabinet-model on the KPA.
I was juts surpised at the difference...had heard a few times on this forum about how good FRFR speakers are but this brought it home...
See- we weren't just making this stuff up
it really makes a difference, doesn't it?
Cheers Heldal, it's just you never think about these things with a regular amp... what you say makes perfect sense and I guess is obvious if you do think about it.
I never doubted you Paults
LOL!
