Hey all.After having 6505/Powerball II/5153 for a while i am looking for a change from the compressed sound to something more organic.I've heard clips of Mark III and Mark IV on YT and really liked the sound of these amps.I play mostly Metal from 90s power/thrash to death metal to modern stuff. A local ad came by for a Mark IVb Combo version and went to try it out.I was a little underwhelmed tbh it just wasnt aggressive enough,the gain was barely making it,too dry,not much of a low end and not as open sounding as i believed it would be.No pedals used. Now i am thinking i may misjudged the amp based on circumstances.First obvious thing is the fact its an open back combo with that 90w black shadow speaker.Second the seller said it has its original tubes in it so it might as well need retubing.Lastly i didnt have enough time fiddling with the amp as its confusing AF and i propably need a week to just get acquinted with how it works. I have an ENGL 2x12 which i plan on using with the amp as well as the usual ns gate,808,eq on the loop for shaping sounds.Boogies are very expensive here though and i dont want to spend that kind of cash and have to fight with the amp to get a decent high gain sound. Did i just hear a bad representation of the Mark IV based on the above?Any owner here can chime in on the subject?Thanks.
