The 2500 features the new Hartke silver face chassis and includes selectable passive or active inputs, tube and solid-state pre-amps, variable compression, a 10-band graphic EQ, high/low frequency contour control and XLR direct out. The new Hartke 3500 features the same performance and features of the original model released back in 1990, with 350 Watts of clean Hartke power and punch. The 3500 includes selectable passive or active input, tube and solid-state pre-amps, variable compression, 10-band graphic EQ, high / low frequency contour control and a direct XLR output.
