So I was realizing the truth: my sound cold be get out only from a valve (pre) amp...

than I searched about used marsall combos in my area, and GOAL!!! I found a lightly used mashall 72115 a valve pre amp with a 15'' + tweeter...

I tryed and instantly realized Oh My God!!! this is my sound !!!! Yeah!!!
buyed and carrryed in my car!!!
It Sounds so organic, so full sound, so bad screacthing sound!!!
the dynamic is so powerfull (only 200w rms but 2000w peak!!!)
fortunatly I've found it just few months before starting my band's new album... I'm very exited from this sound and how it will forge our new trio funkcore recordings
