Are there any stompboxes that you like to use when recording? I have the MXR Custom Audio Electronics Boost/Overdrive pedal designed by Bob Bradshaw, which I like very much and use quite a bit in the studio. And I also have a couple of old T.C. Electronic pedals, including the Booster + Line Driver Distortion, which has a little EQ on it. I only use the clean boost side of those pedals, though, mostly to compensate for the low output of my pickups. I like pickups with low magnetism because the strings aren’t affected by the pickups so much. A lot of people don’t realize how much that affects the sound.
