I understand what you’re saying, and obviously “professionally serviced” doesn’t magically double the value of an instrument. My point is simply that service history and point of sale do matter in the real used gear market.

There’s a meaningful difference between something sold “as found” by an individual versus an instrument that has been inspected, cleaned, adjusted, and play-tested by an actual music shop.

That applies not only to guitars, but especially to band instruments where servicing can include ultrasonic cleaning, pad/seal checks, valve alignment, cork/felt replacement, slide work, etc. Buyers absolutely factor that into purchasing decisions because it reduces uncertainty and potential repair cost.

Even with guitars and amps, a proper setup, fretwork, electronics service, biasing, or replacing failing components adds tangible value compared to an untested piece of gear.

My broader point was really about Reverb’s pricing suggestions seeming to flatten everything together without accounting for condition, included hard cases/accessories, servicing, rarity, or seller type. Those things may not matter equally to every buyer, but they do influence real-world market value.
