do effect pedals with amp sims/modellers make your actual speaker amp sound bad?

    If one is to use the amp sim/modeller from an effect pedal (ex: Zoom B1XON) while using a bass amp/cab (EX: Peavey Minimax with Gallien-Krueger Neo 212), would that make the outcome sound muddy then? So what's the point of an amp sim/modeller? Is it more for recording and or for full range/flat response type of speaker amps?

    For recording and going direct/FOH without amp and cab.

    I’ve experimented, and generally haven’t been happy running a sim directly into my amp.
    I have been happy running it into the efx return on my amp, bypassing the pre-amp and just hitting the power amp w/ the amp sim.
    Then you have full control of sound w/ sim without having to try to balance two preamp sections, or w/o having to get just a dedicated power amp.
    (Edited last sentence for clarity.)

    cab IRs are what make the sound muddy when running a modeler into a amp+cab, not amp/preamp sim.
    you can stack amp/preamp without problem (except od/distortion but is it really a problem ...?) but never use an IR with a real cab
  5. They can make things sound worse or better depends on how they are adjusted.

    This has been my experience with a Zoom B3. It depends on the amp being modeled and it's cab but IME I'd say less is more when using a cab sim along with the amp model when playing through a typical bass rig. It also help to adjust the amp EQ so the response is flat or as flat as possible. I haven't found it to be muddy as much as just not all that good in some cases.

    If the amp has a post EQ effects loop I'd use that and expect better results by avoiding the amps preamp section completely.

    I simply use my ZOOM B3 for the effects alone and run it in the effects loop. I have used it as a pre-amp and run it straight into the effects return with satisfactory results. My new Fender Rumble Studio 40 is far superior to the ZOOM's amp models; cabinet simulations, and effects. The ZOOM B3 is now up for sale.

    Amp sims/modellers vary in price and Quality.

    So turning the amp sim/modeller makes it just an effect pedal, right? Does that sound good then?

    I'm not sure if the same is also true for guitar pedals with amp sim/modellers? Would it also sound muddy if used with a guitar amp (combo, amp/cab, etc.)?

    What's an IR?

    IR = Impulse Response which is a method to meassure and emulate speaker response. In a normal bass rig, the signal path is preamp->poweramp->speaker. A sane way to use your gear would be modeller with speaker sim/IR turned off->poweramp of your bass amp (effects return)->speaker. Connecting two preamps or two speakers in row would lead to somewhat strange and complicated response/tone.

    My question is why would you use an amp sim while using an amp?

    You wouldn’t soak your signal in reverb, in a hall with a natural ambiance and expect it to sound good...
