Hello ,
               Sorry I missed this thread. Well yes I love playing slide and have a few faverites .
               I like using a remake of the"Blues-King" LOO by Gibson. It has great presence and lots of trebble and high end . It is very good in both G and D tuning . I travel with this instroment. Its light and loud.
            I also play a mid 30'd Deolian national steel that sounds and reacts like a 1949 dodge power-wagon . Nothing comes close when you need that presence! It is great in both D, E, G, and DADGAD. Incredable warmth!
             I also like using and early Kallamazoo ( the 30's model that has the big sound hole. ) This guitar loves very heavey rythmic playing and is very very bright.Those high note slide responces to its wonderful hard thummping bass hitting is a very special sound..It likes lighter strings..   I play it in G or A more then anything else. It has a very particular voice on a good mike .<><<>
               Finaly for some studio work I just love this very funny Pearloid covered Kay " Proffesional" that is an arch-top with F holes and a very even voice across all the strings. I have used this guitar to record a lot of slide work. It is bright but also has some wonderful undertones.
                Ah just one more. For certain moments a telacaster cant be beat !!
                Lately I got my younger son a wooden bodied modern National Resonophonic guitar that is just amazing . It covers many of the bases talked about here.Its bright and has a very strong bass voice but is very even across its range. It is an amazing instroment. If I was only playing slide out it would be a very strong choice for gigging. I would put a pick up in it tough for that.
                As Bert alooted to you can make any instroment sound good by sticking with it and getting used to IT'S way... Today I was playing an old 50's little Harmony that I keep at my pottery shop and in G tuning it filled the room with great music. Lots of the best slide work recorded out there were played on simple instroments that a great hand just got used to . Slellas got palyed to death and thats probably why we cant find many of them still playable.
                Great thread . Keep slideing all here !!! All the best , Guy
