Talking about cabs that are able to swap between 8 ohm and 4 ohm, via a button or switch or something. Does such a thing exist? If so can someone give me some names cos I’d love to take advantage of this technology. Imagine, u have 1 head, and 1 cab, that u can use for both practice, jamming and gigging situations. Set up in your bedroom? Switch it to 8 ohms to get the lower power. Got a gig? Have no fear, swap it to 4 ohms for the extra power. Seriously I want this.
