Currently I have a Kustom Tube 12A (12W Hybrid amp) and ive noticed on the back it has a external speaker jack. The amp has a 8" Celestion super 8 as its speaker currently but will getting say another cab improve the sound in anyway? Im not an expert on amps im just wondering. Thanks in advance.
it might provide a 'fuller' sound due to spreading the sound waves out and could possibly provide more low end depending on what you go for but i'm not a cab expert. In some amps if you plug a cab in it disconnects the current internal speaker - which won't help you so you need to check into that and ohm (impedace) rating of amp and speaker.
