Hi ty
I've never played a wide Q5, sadly, so I can't comment there.
the Q6, however, it one of the most playable and comfortable 6s I've ever come across... my fretless feels very very easy to use, and currently I'm using a fretted solid bodied Q6 as well, which sounds amazing. If you do get one, go with Aguilar preamp, as it sounds great...
the difference between solid and hollow is kinda subtle, but the hollow one feels slightly more resonant, with a more controlable midrange... I'm really enjoying the solid one as well...
I'm really glad you like the CD - please play it to your friends, and let them know where they can get it...
take care
Steve
