    I love the original Xotic (EWS) Tri-Logic preamp. For all of you who have tried the smaller Tri-Logic II and the new Tri-Logic III how do they all compare? The knob configuration on the new vIII seems a bit awkward but aside from that what are the tonal difference (if any)? More gain on hand? Are there any tonal/frequency differences between the II and III?

    Lastly, if you had a Tri-Logic and selected another preamp, please do tell why.

    I've had the II and am currently using the III, it does have a lot more gain than the II but aside from that and the added EQ flexibility, they sound pretty similar.

    I had a v2. It sounded great but the EQ range felt like it was quite narrow, no noticeable difference between settings. Which may be a good thing because you don't have extreme EQ spots. At some point I sold it to try something else.

    I think the main advantage of the v3 is that you can use a 9v adaptor and the voltage is doubled internally. The v2 requires a 18v adaptor.
  4. You can run the II on 9v as well. You won't get the full headroom but it still souns great! :)

    I actually run my III at 9V, no headroom issues

    I have the Xotic Tri-Logic (larger box) and had the EWS Tri-Logic II. They sound identical, as far as I could tell.

    My preferred 3-band preamp pedal is the Fodera. The Tri-Logic sounds good, but the Fodera sounds better to me.

    The Tri Logic II is a great pedal, I cant run it on my 18v 1000ma adapter though as it whistles when switched on, seems like a common problem, I think I need a transformer type rather than the lightweight switching adapter, BUT on my 9 volt 500mA adapter it runs dead quiet and don`t seem to have any issues with headroom. How long do you people get out of the 2 x 9v batteries ?, I had an Aguilar DB924 which you could only run on batteries and I got nearly a year of regular gigging out of them !
  8. It had a nice EQ, but the overdrive wasn't for me at all. It had the SVT/sludgy swamp thing going on.

    I found I could get a better tone/money expenditure elsewhere for my needs:)
