I have a Korina Explorer with a Custom 5 in the bridge and a Seth Lover in the neck. I find the Seth is too muddy and dark in this guitar, but it's also lacking in gain (or is output the correct term) compared to the Custom 5. It's not a volume difference per se, but notes which sing like crazy in the bridge position just die with the Seth in the neck. Does anyone know how the Jazz might compare to the custom 5 as far as gain levels?
