If you're just going to trigger your bass I'd go with a cheaper module. The Roland one looks nice, but I don't know too many people besides a studio that would spend upwards of $1,500 on something like that. The individual Roland triggers for bass drums go for about $79 and up so if you coupled that with a module that cost $350 that wouldn't put you too much out of the bank. For me personally, I'm not a huge fan of triggering stuff except for bass drums...and even then I'm not too wild about that. The only thing I'd spend $ on is two triggers for my two bass drums and a cheap module to run it through. In a cost benefit analysis, unless every drum is being triggered on the kit and you have nine toms, roto toms, timbales, bongos, congas, pots, pans, etc., then it probably isn't worth the difference between $350 and $1,500 for a couple hundred new sounds probably only an 1/8 of which would be applicable to the bass drum category. Funny though how some people from the metal genre of music are bad mouthing triggering since it seems to be most popular in metal music in general at the moment. Recently I've seen quite a few "hordes of nords" Black Metal bands (not my thing) where every single drum is triggered (on a large acoustic kit). I then think to myself, "Why even bother with an acoustic kit? Why not just get an 'electric' kit with a bunch of pads?" The only word I can think of to describe the sound is...plastic.
