I have a D-Tar Equinox preamp/parametric eq/notch filter that's acting really strange. When the power is connected, the green power-on indicator doesn't come on, but the red input gain clip light stays on. When I disconnect the power, the red clip warning led goes out but the green led glows for just a second. And obviously, the preamp isn't working. Realizing it's a long shot, but this thing is essential for shaping my upright tone for hi-gain situations. Hate to buy another if it can be fixed. Anybody else seen this?
