What is your opinion of this product?
As the previous reviewer wrote it is overpriced, low quality also. I purchased a GSP1101 from AMS, and after receiving the unit I plugged it in and the display was not working. They made good on their warranty , and sent me a new unit that worked fine. Now two and a half months later the display is not working correctly on the control 2. I will have to take it to an authorized DigiTech repair center to get it fixed. I should have gone with my first notion and steered clear of DigiTech. Never again my friend, never again.
