Hi guys, i just bought this head and i am quite impressed. first off i only paid $450 for it shipped (i live in so Cal) and it sounds really good. I'm playing it using a SWR Goliath junior II(2x10 are so much better than the 15" combo) and my Ibanez SR-400. The bad: well there's a lot of noise. when i have the tweeter turned on there's this very annoying high pitch sound that's very noticeable. Without the tweeter it is relatively quite, though if i wasn't playing the bass i would probably keep it off. Any suggestions on how to reduce noise? is it my active bass? The Good: Damn good amp for the price. Ive shopped around and for other heads and with this head you got alot of bang for the buck. The yorkville is not as bright and clear as i would like it. but the tone is still good. The yorkville is transparent and the tube pre-amp is a very nice touch but i wouldn't say it's a tube sound. It's more like half and half.. it has the characteristics of the tube but not the feel of a tube. (if that makes sense) VERSATILITY: this head can get you alot of sounds. I was playing it and realized that the controls on this head really let's me shape my tone. Especially when i use the scoop, the parametric mid and the tube pre-amp. You could get a lot of sounds from it. The Ugly: My bass playing, haha i need to get better. Man i hear some of the people here and i'm like man you guys rock. Summary: very good for the value, Dude you're getting 400 watts at 4 ohm for $450 This head is very versatile. Kinda annoying noise but i think that it would change if i used a passive bass. I highly recommend this head to anyone on a budget and want's a cheap affordable head that gives you the flexibility and power for bigger gigs in the future. Off topic questions: 1) If i get a 4x10 would it be considereable louder than a 2x10. 2) If i get a 8ohm 4x10 would is be considerable quieter than the exact 4ohm 4x10? (it's 280 watt's at 8ohm compared to 400 at 4ohm) 3) damn tweeter noise!
