    On the Andertons blurb for the Abasi Pathos pedal it mentions that it is suitable for 'saturating a modelling amp tone'.

    It also says, "Encompass the functionality of several dirt boxes in one; be it a push to a driven amp, a full-on distortion channel in front of a clean amp, or a boost in front of a digital modeller."

    Which made me wonder, is there something specific that makes a boost or drive pedal more suitable for use with a modeller?

    And if so, what is it? And therefore which pedals are best for using with a modeller?

    No. A pedal is a pedal.
    Some have more features and produce a wider variety of tones than others.
    And in the end, some pedals sound better with some amps than others.
    So you may like how a pedal sounds in front of the Deluxe amp model
    better than how you like it in front of a Plexi amp model, etc.
    As always make sure all pedals are powered properly and DO NOT daisy chain
    from a signal power supply. This ALWAYS adds noise to the signal.
    If you use multiple pedals use something like the True Tone Pro
    power supplies to power them properly.

    What an odd thing to claim!!!

    I would have thought that the resulting tone would depend a lot more on the quality of the modeler than anything to do with the pedal. For me it's a non-question. There are certainly times when I'd like a second boost option with my Atomic but I think I'll either wait until that happens with a firmware update or I'll just live without it. The only pedal I use with mine is a wah and if I had any faith I could understand the various parameters for wah on the Atomic, I'd probably change it for an expression pedal.

    Mate I had the same problem when I first tried an expression pedal for wah. Then I found this comparison chart on Sweetwater:
    https://www.sweetwater.com/feature/dunlop/wah-pedals/index.php

    Try setting the frequency range to match one of those. I'll have to check what other settings I changed. You then end up with a manageable, nice sounding wah instead of a wide open frequency sweep that makes your guitar disappear at one end then pierce eardrums at the other.

    Once I sorted the auto-off settings I loved using the expression pedal and won't bother with traditional switched wah pedals ever again. Will post all the relevant settings for you when I get home.

    Why chain drive pedals together? Something I've never thought of. What does it do that boost+amp doesn't?

    The only thing I can think of would be impedance mis-matching. I don’t know what the input impedance is on the Amplifire or other digital modelers vs typical tube amps, but I have never experienced or heard of a problem.

    Depending on how the input stage of any particular modeler is designed, too hot a signal coming out of a pedal can / will also behave differently between an all tube amp and said modeler. As you increase the signal going into the input stage of the tube amp, you get more tube compression / distortion. Into a modeler, you can drive whatever solid state components compose the input stage into distortion (and how pleasant or horrible that sounds is all down to circuit design), and in a bad design, you can clip the analog-to-digital converter, which will definitely sound atrocious. But again, this is all based on circuit design, and I'm pretty sure at this stage in the game all modelers take all of this into account (some better than others).

    Easy solution? As Jace mentioned, some pedals will work better with some modelers, and with some models better than others. Use your ears, and test a range of gain staging options coming out of your pedals. A good modeler will respond accordingly - for instance, try a Big Muff style pedal into an Amplifire with Deluxe / Plexi models, and play with the output volume of the Big Muff vs. model preamp gain. It'll show how different models react in totally different ways to the same pedal, and you'll definitely feel when you run out of headroom and the high frequencies start compressing and sounding creamy... and now excuse me because I need to go and play for a bit. :D

    That's really useful, thank you!

    I've been toying with getting rid of the wah in favour of an expression pedal for ages and just never got around to it but I'm visiting the UK at Christmas so I think I'll make the switch then. Now I just need to work out which expression pedal to buy but I'll ask that on a different thread rather than hijack this one.
