"Jazz" pickups (referring to the original Fender Jazz Bass), also referred to as "J pickups", are wider eight-pole pickups that lie underneath all four strings. J pickups are typically single-coil designs, though there are a large number of humbucking designs. Traditionally, two of them are used, one of them near the bridge and another closer to the neck. As with the halves of P-pickups, the J-pickups are reverse-wound with reverse magnetic polarity. As a result, they have hum canceling properties when used at the same volume, with hum cancellation decreasing when the pickups are at unequal volume, and absent if the player uses only one pickup. 'J' Style pickups tend to have a lower output and a thinner sound than 'P' Style pickups. Many bassists combine a 'J' pickup at the bridge and a 'P' pickup at the neck, so they can blend the two sounds.
So, let's say you've got all of your percussion picked out and set up - does it end there? The answer is: only if you want it to. Keeping it simple is just fine, but if you're the sort of drummer who wants everything personalized to a tee, then it's also worth checking out the selection of drum accessories and hardware. Full of ways to modify your percussion or change the way it's set up, these extras can give you the extra touch of customization to make a drum kit truly your own.
Most electric bass guitars use magnetic pickups. The vibrations of the instrument's ferrous metal strings within the magnetic field of the permanent magnets in magnetic pickups produce small variations in the magnetic flux threading the coils of the pickups. This in turn produces small electrical voltages in the coils. Many bass players connect the signal from the bass guitar's pickups to a bass amplifier and loudspeaker using a 1/4" patch cord. These low-level signals are then strengthened by the bass amp's preamplifier electronic circuits, and then amplified with the bass amp's power amplifier and played through one or more speaker(s) in a cabinet.
Since there are so many digital pianos worthy of your attention in this catalog, you may want to narrow down your choices using some of the search options on the sidebar. For example, if you select stage digital pianos under the category section, you'll be presented with all the digital pianos that were made for the stage. Once here you have the opportunity to drill down even further and can search by topics like number of keys, MIDI/USB Connections or by whether or not the digital piano has built-in speakers.
