Help guys, I`m playing in a band with 2 loud guitars playing original hard rock stuff, and play mainly a stock Fender P Mexico through a newish ( 1 yr old ) Hartke hydrive combo, the 2x10, 250 watt version. I have to run the volume control up to 6 out of 10, and if I put much in the way of e.q. on it the speakers struggle and begin to distort. This is much worse when used in kick back position. I`m not sure if it did this from new or if it`s got worse, as the band has got louder and louder, so now not sure if it`s a speaker fault or just the inevitable " headroom" been reached, I realise that amps and speakers peak and distort long before volume 10, but am frankly a bit disappointed. Hartke claim it`s almost impossible to overdrive the amp, but I`m doing it easily!!!! Any advise welcome!!!!!!!!
