after some time, i have come to the conclusion that i think i need more power... perhaps someone here can verify wheather or not this situation makes sense. i have a walkabout 4 ohm 300w head and a peavy 4 ohm 400w rated cab (1x15/2x8). i assumed that there was no way that my amp could distort the cab, since the power rating on the cab was more than my amp could produce... but.... now i am thinking that the reason my cabinet is distorting when the amp knobs are at about 5 on the preamp and 5-6 on the main, is that the amp itself is maxed and is sending a distorted signal. does that sound accurate? so, what i wanted to know, is since my cabinet has a bi-amp area on the back... does that mean i could possibly buy another amp head (like say a smaller 100w additional amp) and run my 300 watt walkabout and another 100watt head, (maybe a lower wattage hartke or somehthing) to my single cab simultaneously to get louder sound and less distortion. does this sound like it would work? the other option i was thinking about would be buy another small combo with a 1x15 and use the y cable (that i read about here) to run both my walkabout (with scout) with the before mentioned small combo. i love the walkabout sound so much and for my upright gig, it is killer, but my other rock gig... well, it just seems to be almost enough, but not quite. and comments or ideas?
