Humphrey Espresso 30S Spalted Maple and Barista Speakers

No sales tax for US customers outside California.

This Humphrey Espresso 30S is a boutique 30-watt guitar amplifier wrapped in stunning spalted maple cabinetry and paired with their Barista speakers—an aesthetic and tonal combination that instantly sets it apart.

Built for players who want rich harmonic response, responsive touch sensitivity, and high-end boutique character, the Espresso 30S delivers a warm, articulate voice with plenty of dynamic headroom.

Bold yet refined, the amp blends hand-crafted woodworking with studio-grade circuitry. The spalted maple shell isn’t just visually striking—it adds resonance and an organic liveliness that complements the Barista speakers’ smooth midrange and airy top end. Together, they create an immersive playing experience that feels alive under the fingers, whether running warm cleans, edge-of-breakup textures, or harmonically rich overdrive.

This example is in excellent condition with only the lightest signs of careful use. It sounds huge for its size, responds beautifully to guitar volume changes, and pairs effortlessly with your favorite pedals.

Shipping policy:

When you purchase this item you are hereby agreeing to this shipping policy. We remove tubes from amps that could be damaged in shipping.  These cases require the buyer to re-install them on delivery.  These cases require customers to reassemble amps.  We do this because we have experienced shipping issues in the past, and this is our prevention measure.  Vintage amps are sold as-is because they can need service intermittently.  Everything is tested here in our shop on the way into our inventory, and again before shipping.  We will cover shipping damage, but we cannot be responsible for the failure of vintage components in 20-to-50-plus year old amps. Shipments will require signature on delivery, no exceptions.  If there is damage, the buyer must retain all packing materials intact and picture them immediately and send them to sales@maharsvintageguitars.com.  Less than 1% of our shipments are damaged in transit, and we are committed to making sure your item arrives safely, but we are taking these additional measures to make sure you are happy with your purchase.
