I have a Boss SD-1 pedal. I like the grit I get from it and the clarity is about right, but there's a definate lack of bass and I don't like those honkey mid's. I know that Keeley mod's these pedal's as well as one of our forum bro's here. (Can't think of his name, offhand.) Anyway, once modded is there a definate improvement in bass response as well as taming those mid's? Who does the better job with modding these pedal's? Thanks.
