The Marble Harpwood is a dedicated blues harp amplifier with a completely new tube design using four special design 8" ceramic Marble Bluetone speakers. This amp features an upgraded preamp circuitry which is capable of handling all the famous harp sounds in the Blues; ranging from authentic early fifties riffs up to heavy overdriven soloing.
The smooth overdrive characteristics with enhanced harmonics and reduced harshness are especially important qualities of the Harpwood.
From scratch Marble have redesigned the preamp which now offers a totally new set of tone controls. To begin with the Harpwood offers high and low inputs and a preamp volume and tone control. The circuitry behind it is simple and has some similarities with fifties Gibson, Fender and Ampeg designs. For full tonal versatility a unique magic contour control developed at Marble amps has been fitted.
The contour knob dials from fat & compressed mid focussed sounds to more open texture with lots of massive bottom end .
The control panel also offers a master volume that operates just after the preamp and controls the amount of signal passed to the powertubes without affecting tone. The latest addition on the Harpwood is the Anti Feedback Circuitry which is located on the bottom-side of the chassis. It effectively reduces the feedback sensitivity of the poweramp while maintaining overall tonal response. This enables you to play at higher volumes without feedback.
The HarpWood is available in your choice of either tweed or tolex covers.
These excellent amps are custom made to order and take 2-3 weeks to be hand made at Marble. The price (although high) represents very good value compared with other boutique amps in its class and should be considered an excellent investment that will return years of satisfaction.
