Several parts to this... 1) Anyone ever dealt with Low Down Sound for custom cabinets? How do they compare to some of the other "name" brands in terms of construction, sound, customer service, and price? 2) What other options exist for custom cabs? 3) What are some good questions to ask both myself and a prospective builder to make sure I'm getting what I want and need? Basically, I'm thinking about seling my current, oversized rig (Ampeg B-248 combo with a old Avatar 15" extension cab) and moving to something more modular and portable. Custom cabs are an intriguing option, but I'm worried about my own lack of knowledge/experience/expertise -- not to mention my potentially tight budget. Any input at all is much appreciated!
