I have a Kustom 215H Groove Bass cab and want some additional upper frequencies. Should I add this cab? http://bass-guitars.musiciansfriend.com/product/GallienKrueger-210BLXII-Bass-Cabinet?sku=601056 I am, primarily a keyboard player and vocalist, I was asked to play bass recently and have dived back in! I last played a Fender Precsion 20 years ago. Man did my fingers kill me for a month!!! It's all come back and I'm capable of most styles minus some radical jazz.
