Power amp

    Hello,


    On this moment I use the kemper through FRFR (RCF 312 mk3). I was pretty happy with this setup until I pluged in the kemper (main out) into the input (No send and return available) from my old London City DEA 130 watt top (all tubes). I think about switching between frfr and power amp with cabinet. Because the london city is not so reliable anymore I am looking for another affordable alternative power amp that is some kind of similar to london city, or just works good with KPA. For example the Jet city jca22H which i Like for what i Heard on the internet.


    I like to hear some suggestions.
    Txs!

    Hi, i dont know if i use the term in a right way, but i think that it is the amp in the room effect that made me change my mind. With my rcf 312 there is always a sort of blanket over the sound. And with my yamaha hs10 with sub monitors, heavy sounds are clear but does not rock in my opinion. The LC makes it all breath a little more. Feedback that turns beautifull harmonics etc etcetera..


    Ps.. The cabinet is self home build with 4 old fane speakers i think 10 inch speakers, not sure, a friend give it to me long ago

    Hey Meul,
    The main reason why your amp sounds good with the Profiler is that it's an amp with a very open sounds, known for ots resistance to distortion. Bassists like it.
    I'd take my Profiler in a store and try bass and keyboard amps gifted with an open sound. Usually these have good punch.


    If you have to use the instrument input in the amp, be sure to not raise the Profiler's master volume too much, to have a more linear sound.
    Also, remember that in the Output settings you can save presets properly eq'ed for different amps, this way you won't probably be obliged to re-tweak rigs (or use different ones) when you switch between the amp your monitors.
    :)

    @ Ingolf, thanks for your advise!


    Hey Viabcroce,


    If you say the reason that it sounds good, do you refer to the London city or tube amps in general?


    On this moment I am interested in the Jet-City, jca 22H, 50H, or 100H or the Bugera 1960 INFINIUM (150w). I am interested because this are full tube ‘low budget’ solutions with a send and return so I can use the power amp section. I am not sure if you know the LC 130 personally, but if you do, do you think this will give the same results compared to the main low input of the London City or better seek for a bass or keyboard amp?

    Yeah, I was referring to the London City. Bass players use it. It's not really a "rock" guitar amp from what I'm reading around, and IMO this is why it sounds great with the Profiler: because it's more linear (let's say "clean" and "open") than say a Marshall.
    I don't personally know any of the amps you mention, but I'll renew my hint about trying very open, tube bass/keyboards amps, which would be the closest to what you have experienced.


    Of course you might later on find that what best sails your boat is a more rock amp... LOL But you should not choose basing on how good the amp is reported to sound with guitars: you're are using a top-quality modeller, which already takes into account all the non-linearities a guitar rig has got.

    I'm surprised with the OP's experience, though tone is of course subjective. I wouldn't want to run my Kemper into a tube amplifier, because it's likely to colour the sound. This effect would be magnified if you raise the volume of the amplifier and also if you push it harder with the Kemper. This would add to the uncertainty in sound, since you are unlikely to have the same results night after night using tubes, unlike a solid state power amp.

    I don’t want to discuss this in terms of good and bad. Indeed a personal opnion. There is something I like very much about the Kemper>LC setup. So much that when I switch back to my FRFR it feel like riding on a dead horse. (choise of animal also very personal :| ) I am tending to assign this difference to the properties of tube amps. I borrowed a behringer nu 1000 transistor bass amp. Now I can compare, just have to try it out now.


    Update! Kemper > Behringer NU1000 power amp > Homemade Cabinet, this will not make the big difference compared to use my FRFR Rcf 312 mk3 (active) speakers  Other sound, yes, off course with another cabinet, but same feel/response. I miss something, what is t, what is t ???

    Mhhh.. Meul, IMO the underlying problem is a too simple approach to "FRFR Vs. not FRFR".
    Pretty sure, if you tried other so called "FRFR" options you'd get a very different sound than your RCF.
    For sure, a non-linear sound solution will impart a sonic signature to any rig.


    IMO, you'd benefit from a different approach to digital devices in general: you should realise that all the components of the sound you have in mind are implemented in software. While in the guitar amps/cabs realm you change brands and models and add fx to shape your tones, with a Profiler you operate on the machine to get the results: changing settings/profiles/cabs equals swapping tubes, cones, transformer... and build the amp/rig you want to hear.


    For your mind's peace, I'd spend some weeks just exploring the Profiler's controls and check how much you can transform any profile to something completely different. Record a lot of clips for yourself, specially over some tracks (D&B, for example). Play on records as well. You'll see how well the Profiler performs with other musicians (i.e., fits a mix) if you learn to use it.
    You seem to need sonic reference points.


    I'd also go to a store and use some high-end PA system, just to see how glorious the Profiler sounds with a great cab.

    Hi Vibracore,
    I am not sure if I understand you right? I have no complains about the sound of frfr, but more about the feel, playability/response input/output when playing. For recordings and how it fits into the mix I I have no complains. I did some recordings with the Kemper and I am very content with it. But on the monitoring site I miss something. Not only with the rcf’s but also with the Yamaha dxr10, rcf nx, etc.. yes, they all sound different, but has the same digital feel. Also the bass transistor power amp from behringer for my cab did not changed that. So I also have the problem with non FRFR tho it feels more into the room.
    I am now busy with orientating for tube power amps or guitar tops with send and return. Hoping/seeking for the best of both worlds.

    I guess it's more to do then with hearing a sound on or off axis, because there is no 'digital feel' to a high quality FRFR cab like the DXR 10.
    Some people simply want to hear their sound off axis, the infamous 'amp in a room', and there's nothing wrong with that.
    I suggest you take your time and check out what you like. ;)

    Agree with Ingolf :)
    I'm sure you'll find what you're after, if you know what it is :)


    Just out of curiosity, have you ever listened to a Profiler from the audience at a concert via a PA? Did the sounds sound digital to you?
