I am on the hunt for an octaver pedal. According to the reviews the "worst pedal" is octabass comparing mxr and aguilar. The thing is though that I love the octabass tone that I listen from the clips. Most of ebs users say that it does not track well, do you think that putting a compressor pedal before the octabass would improve the tracking? I also would like to ask your opinion about someting else. The octabass costs 125 euros new, someone sells a buffered black label for 60, he also claims that it is in "like new" condition. Do you think that it worths or is it better to go for the new true bypass one? Thank you!
