I worked with Dave of The Sound Parcel through Reverb.com on a purchase of a GFI System Specular Tempus guitar pedal. I am very impressed with the prompt attention he gave to my question about the proper power supply needed to operate the pedal. Not to be forgotten is the free 2 day shipping that was another bonus with The Sound Parcel. I usually deal with Sweetwater, a very popular internet site for music, but they don’t carry GFI products so I was very lucky to find Dave at The Sound Parcel right in my neighboring state of Pennsylvania! I will definitely keep them in mind for future purchases. You should too!
