The Ampeg Fliptop is the definitive one-and-done bass amp for studio and low-wattage live use. As the name suggests, this B-18N model sports a larger 18" speaker, compared to the 15" speaker in the B-15N models. At one time, this amp had Kustom tuck-and-roll covering over the original tolex, which has since been removed. During that process, the top panel holding the amp was trimmed slightly, so the fit isn’t perfect, but it still secures just fine. The original grillcloth has also been replaced.
Internally, the electrolytic caps and power cord have been updated, but everything else is stock. The original 18" Cleveland speaker is still on its original cone, which sounds a bit tired at this point—for those who enjoy hearing speaker compression, it's certainly a vibe. The bottom caster portion was added and is a welcome addition for easier transport. Wonderful vintage Ampeg class on display here!
