This is all very interesting as I am considering a MQ in the neck of my SG
I'm trying to think of a guitar to add to my stock that would be good with a MQ neck. I'm thinking a 335-type with a pair of MQs...
On the subject of the MQ and P90 types, anyone know which BKP P90 the MQ is based on? I'm guessing BKP-91.
I'll probably get a set for my Pete Townshend SG eventually, but the P90s are the type which attach to the scratchplate rather than the body, so I might need to go for rewinds rather than new pups.
