Operace
Ovládání je ukončenoview
Your Sadowsky MetroExpress bass features a comprehensive control layout designed for maximum tonal flexibility:
- Knoflík hlasitosti: Ovládá celkovou výstupní úroveň basů.
- Pickup Blend Knob: Blends between the P-style split-coil pickup (neck position) and the J-style single-coil pickup (bridge position). Turning it fully counter-clockwise selects the P-pickup, fully clockwise selects the J-pickup, and the center position blends both.
- Passive Tone Knob (Push/Pull): In passive mode (knob pulled up), this acts as a traditional passive tone control, rolling off high frequencies. In active mode (knob pushed down), it functions as the treble control for the active EQ.
- Active Bass Knob: Boosts or cuts bass frequencies when the active preamp je zasnoubená.

Úprava tónu
Experiment with the blend knob to find your preferred mix of the P and J pickups. The P-pickup typically offers a thick, punchy tone, while the J-pickup provides a brighter, more articulate sound. Engage the active preamp by pushing the tone knob down. Use the active bass and treble controls to further sculpt your sound. The active preamp requires a 9V battery for operation.
Přístup k baterii
The active preamp is powered by a 9V battery, located in a compartment on the back of the bass body. To replace the battery, open the compartment cover and insert a fresh 9V battery, observing correct polarity. Always unplug your bass when not in use to conserve battery life.

Údržba
Čištění
Regular cleaning will help maintain the appearance and playability of your bass. Use a soft, lint-free cloth to wipe down the body, neck, and strings after each use. For stubborn grime, a small amount of guitar-specific cleaner can be used on the body. Avoid harsh chemicals or abrasive materials.
Výměna strun
Strings should be replaced periodically, depending on your playing frequency and preference. Old strings can lose their tone and intonation. When replacing strings, change them one at a time to maintain neck tension. Use high-quality bass strings of the appropriate gauge.
Skladování
When not in use, store your bass in a suitable gig bag or hard case to protect it from dust, impacts, and extreme environmental changes. Avoid exposing the instrument to direct sunlight, excessive heat, cold, or humidity, as these can cause damage to the wood and finish.
