Optical pickups are another type of non-magnetic pickup. They use an infrared LED to optically track the movement of the string, similar to the mechanism of modern computer mice, which allows them to reproduce low-frequency tones at high volumes without the "hum" or excessive resonance associated with conventional magnetic pickups. Since optical pickups do not pick up high frequencies or percussive sounds well, they are commonly paired with piezoelectric pickups to fill in the missing frequencies. LightWave Systems builds basses with optical pickups.
Finally, the last but not the least, you need to consider the price of the guitar when purchasing a bass guitar. Before setting your foot in the store, you need to set a budget in your mind for how much you want to spend. As a beginner, you will probably want to take a look at the entry level models. You can pick up one that sounds quite nice for under $500. If you are still uncertain whether you want to make it a full-time commitment to playing the bass, try to look for a cheaper model. A decent guitar can be had for around $200. Try not to be tempted by some shiny, more expensive models as they are beyond your skill level at this point may be. You can always buy something more advanced and high quality when you get better in your bass guitar training.
I brought in several other pianists for our test panel. Liz Kinnon is a pianist/arranger/composer/educator from Los Angeles who has performed with artists such as Dizzy Gillespie and Andy Williams. She was an orchestrator on the animated shows Animaniacs, Pinky and the Brain, and Histeria. At the Colburn Community School of Performing Arts in Los Angeles, she teaches jazz piano and is the Director of Adult Jazz Combos. She was Ryan Gosling’s piano coach for La La Land and recently worked with Simon Pegg and Juno Temple for the film Lost Transmissions.
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.
