Have you guys updated to the 2.0 version. We did address some of the level issues people were having there.
If you need a further boost than that you may want to flip the input switch to guitar and the output switch to line. This will give you a 6 dB boost through the delay, however it's actually in the output stage so it can't be saved with a preset and there isn't really fine level control there, but maybe worth a shot.
