I had an ENGL Thunder head that was pretty amazing. 50 watts of dynamic raw power, it sounded like a 5150, but more clear and just better. But I bought a Blackstar HT-100 head cause I wanted to have a more agressive tone. Not the Series One head, cause I think the amps with great mids sounds better than scooped modern voicing heads and HT-100 give me more than this. I'm so satisfied about my tone. It's lead channel sounds like a modded, perfect Rectifier with a lot of punchy mids and f*cking fast reaction for my picking. It's a beast, so clear and punchy and silent as well. Clean is the best clean channel in a higain amp. It's heavy as hell, about 22 kilogramms and big like Marshalls. Anybody play on it is very surprised that amplifier can be so agressive and clear.
