I have an EBS octabass, it's a very sweet sounding, clean octave pedal. I use it on thriller live on tour (clang!), and it's warm and musical. I've borrowed other octaves and currently have an OC-3 on loan for other gigs - I find that pedal very aggressive and slightly 'narrow' in it's tone. I wasn't a huge fan of the EBS when I got it, but the more Octavers I use the more I realise what a nice warm musical octave it gives, especially for RnB, Soul, neo soul type sounds. Worth checking out. Aguilar one is quite sweet but for me/my bass it didn't track with great authority.. Worth trying a bunch if you can, and check out that EBS, I really like it.
