I have a Cali Compact Bass and a Warm Audio WA76 to compare it with. I decided for the transformerless version, 'cause I liked all the other possibilities and the size of the compact (the HPF for example). The compact sounds very very good, no doubt. But simply for the beauty of it and Origin Effects being the only company selling a kind of credible 1176 clone with a transformer in pedal format. They shouldn't discontinue it!!! But client demand doesn't go along with my wishes and as I think about it again: I'm responsible 'cause I ordered the compact.
