Hey Miles,
Maybe you can help me. I was just wondering if you could help with some background about an amp. My dad has an old Guild Amp which I assume is from the 60s. It seems to be similar to a fender deluxe. The model appears to start with 66-...but it is barely readible after the hyphen. It has 4 inputs 2 labeled guitar and 2 labeled microphone. It has a 2 volume pots for each channel with a shared high and bass eq. Also, there's tremolo with two controls (speed and intensity) with a 1/4" footswitch jack. I can post some pics once I scan them if that would help. If you need any more info please feel free to ask. Thanks for any help.
