Dumble ODS-100, especially the way it is set up in the 'Katies's Song' preset with the two speaker cabinets and I have Chorus bypassed. I have the Output Compression set to Gain Enhancer with output at 1.6, threshold at -20, and speaker compression set to 0, as suggested in another post. Really comes alive, reminds me of Larry Carlton's Steely Dan days. I also have a version with FET Drive and one with Zen Drive added to the above.
Does anybody know why the preset is called Katie's Song? Its not named after the 'Katy Lied' album is it?
Also love the amps in the presets EJ Clean and Cliffs of Dover, Morgan AC-20, Texas Star and Deluxe Reverb amps - - all with the above adjustments to Gain Enhancer. On the AC-20, I brought the Input Trim down just enough to take out the overdrive that the preset has, and added my own FET and Zen Drive versions. On many of these I tweak Master Volume upwards to taste.
