I had the best experience at custom sounds in Fairview Heights. I dealt with Jeffrey Just and his experience was second to none. He provided much needed advice to make he best decision. Also, they were able to troubleshoot an issue I had with my Fix 86 processor. To cap things off, the shop closed at 6pm but Jeffrey and his team stayed late to finish my installation as well as provide an in-depth demo of my products. I will highly recommend this shop to all of my colleagues!!!
