Well i finaly decided to sell the vigier and get a 24 fret 4 string bass, I have in mind getting either a bongo, a stramer S1 or a thumb N/T. But at the moment the bongo HH looks, versatility and price make me really want one. But the problem i've got with it is that super narrow space between the neck pickup and the neck, i need a 4 string bass to master double-thumping/pluck, so i need room to put my index and ring fingers between the strings and the pickup. Can some of the bongo 4 users, specially HH, how comfortable is it to slap and DT???? And what is EBMM string to pickup recommended distance?
