Speaker(s) importance

[sub]

Day before yesterday ours band come together (some year-end jam ).
I commit a big fault > don't took my cab.
I used a Marsh*ll Va***state's speaker worst sound i ever heard .
My buddy sound was similar with Iba*ez guitar + SS F*nder amp.
I used my G*bson LP and 18W head.
Edification: i will ALWAYS carry my cab

You aren't going to sound your best through a Valvestate speaker cab thats certain! There are times I've gigged with borrowed equipment, never the best idea

Yes, speakers and cab are very important.

Previously i thought speaker is important.
