Hi, excuse my late answer but I am still very busy till the next Sunday.. I would strongly suggest you to find some shop which will allow you to try XT1 on your own.. so you will hear what it will do with your guitar ecc.. I am very happy with this purchase but regarding you I don not know what is your budget.. I hace decided to buy it! no regret!!! .. yes, it is not cheap but any other good guitar would cost me much more.. and I am aboslutely sure that do not want to collect more real guitars than I have (3 guitars and 1 bass) it´s enough!! ...
yes, you can achieve that twangy sound with humbuckers.. sometimes are differences very evident sometimes are slighter.. it depends also on used KPA profiles.. I have no time to make some audio clips at the moment but here you can hear one sample which I recorded long time ago, it is acoustic sound which I obtained from one of Bert´s Acoustic profiles and XT1 simulation of acoustic guitar.. I am quite satisfied with it.. this is my Carvin AH model on neck humbucker:
and I would like to repeat, any other guitar profiles which they sell you can try (endlessly) so you will buy only those you are absolutely sure you will use.. for 10 USD.. all positions of pickups.. and all other profiles of guitars in the forum section are for free..
