I would like to ask you a question since I am not a very experienced guitarist...
I have a marshall 100 hdfx head and would like to purchase a 4x12. I have seen these two models:
1. Marshall CODE 412 Cabinet
2. EVH 5150 Iconic Series 4x12 Cabinet Black
The manuals says
you will have likely decided by now but if you have, I have also heard poor reports about the speakers in the CODE cabinets but saying that I use a MX212A cabinet with my DSL and this has also received many bad reports. I really like the tones I get from it, so each to their own I suppose.
I have heard wonderful things about the range of Harley Benton cabs. They are very keenly priced and can be used in Mono (280 Watt) at 4ohms and 16ohms or in Stereo (2 x 140 Watt) at 8 ohms. I've not used their cabs myself but do own many of their guitars and some other gear that I've found to be well built and excellent value for money. I've been exceptionally happy with every piece of kit I own. These (along with the Marshall and EVH cabs you are interested in) are sold by Thomman with a 30 money back guarantee. I you don't find any kit suits your taste just send it back and there truly is no questions asked.
If you are yet to make a purchase, I hope this info is useful.
