Park P18LH Park ‘Little 45’ Custom Guitar Amplifier Head Review
Built around the early Park P45 circuit made famous by Jim Marshall, the Park P18LH uses full size power and output transformers to keep its tone big and full. The amp produces between 15 and 23 watts of clean power, depending on the tubes and rectifier selected. Its auto bias system supports 6V6, 6L6, and EL34 power tubes, while the switchable rectifier lets you choose between a softer tube feel, more headroom, or a tighter response. The four input setup also allows you to run the two channels separately or blend them together. Its PPIMV master volume helps retain the amp's full character at lower playing levels.
