The HP15 is a wonderful guitar amplifier, completely hand-made.
Makes use of two 6N2P or two ECC83 in preamplification/rectification, selectable by a switch on the chassis.
It is 15W power, it hasn’t a gain stage, so only with a signal booster or using Humbucker pickups it is possible to obtain a tasty distortion into the final stage.
The player can select 5,7,10,15 watts of output power by selecting the configuration/valves to use by two switches, including also the standby.
Two channels, one with tone controls Fender style and one with single-knob liquid tone control.
Completely handmade wood box, excellent design and robustness.
The first AHP® product. Sensibly beloved by guitarists and handmakers.
