Is this bass worth it over a cheaper fretless?

If you want a German-made instrument with US swamp ash and MM-style pickups, yes. Cheaper fretless basses often use softer woods and less stable necks, which matter more without frets.

How does it compare with the fretted Corvette Standard?

Same body, neck and pickup layout, but the fretless board changes the feel and tone. You get more mwah and less attack, and you must intonate by ear and hand position.

What strings and setup does a fretless need?

Flatwound or coated roundwound strings reduce fingerboard wear. Have the nut and bridge height checked, since fretless action and relief are set differently from a fretted bass.

Is the 34-inch scale hard to adapt to?

No. It is the standard long scale most 4-string players already know, so the main adjustment is intonation without frets, not reach.

Expect the bass and basic Warwick paperwork; cases and gig bags are usually sold separately. Confirm with the retailer before ordering.

Fretless Warwicks rarely go on deep discount. Watch for end-of-year sales and open-box listings at specialist bass dealers, and compare against the recent price range.
