i think i have plenty of imagination... probably not to the casual observer since they all look kinda like guitars. but i build guitars because i love them so i am not aiming to re-invent them completely.
Instead i have a list of many guitars i would like to build and many ideas and innovations i would like to try, most of which comes out in my responses here
In the last week or so i have typed repsonses about different types of pickup system (Piezo and optical rather than magnetic) , different materials for trems, the posssibilities for 8 string trems, the purpose of multiscale/fanned-fret guitars, new ideas for lapsteels etc, etc
there is also the projects running through my head i may or may not have mentioned including a headless multiscale re-imagining of the gibson corvus, a bowable fretless bass that can be played upright or normal, something using a fender wide range humbucker and blackguard 50 pickup - most likely in the style of a squier 51 with a different finish. A fretless bass like a re-styled EB0. A double neck bass/12 string. Another lapsteel in a completely different style. A thinline archtop with Ghost flame paint job. a relatively simple bass to try out a BKP P-bass pickup. a electric mandolin. A 7 or 8 string multiscale. etc, etc
some will get built, some will develop into new ideas, some will get forgotten about or pushed out the way by new ideas.
