The V4, in all it's mightyness is sitting on top of my stack. My initial thoughts... it ****ing rocks! I'm so excited. At the guy's house he let me crank it... It's intense! It (his cab) was around 150 W and farting out so I couldn't get a great idea on how cranky this bizzle can get. It sounds AMAZING. It's so FAT, warm, and full. I can't get it to break up, so far, at low volumes, I also don't find much variation from the EQ (this could be from the low volume, tho) - but tbh, it sounds AMAZING set flat! the valves are the original Trace Elliot tubes - it's a '95! - which are relabelled Sovteks I think. Not been inside 'er yet. No biasing control, which has its own pros and cons. I am VERY VBERYVERYVERYVERY happy. It's a TOTAL beast!!! valves forever!
