Hi i need advice on my next purchase, i have the gp7- 7 band e.q. Trace 150 watt head (bought new about 4 years ago) and i need to upgrade to something with a fair bit more grunt... i have about 300 pounds to spend (almost $600) and want a head that offers an even balance between sound and value for money. What would anyone recommend? P.s. I love the sound of my Trace if thats an indication of my preferences, i like the look of the ashdowns and the warwicks, i dont mind solid state, tube/solid combination, or all tube... Please help! i know there are very many experienced players around here, and i value your opinions..
