Yep I won't kid you the Octavius Squeezer does have a very challenging interface. There is a "show all parameters" function which if switched off lets you focus on just those parameters which might be most relevant to a particular preset, which is best for tweaking or fine tuning a preset. Importing patches via an SD card can be very tricky as there's no load or save errors. There's another thread here on Talkbass where all the v11 preset settings got put into a spreadsheet which is very handy especially if you accidentally delete patches!

@gastric has an excellent wealth of information and patches on the Squeezer too.

Creating new patches from scratch is very difficult, but that said the presets or subtle variations on them are pretty amazing. It's a flawed pedal from an interface perspective, but its flaws are very forgiving when it sounds as good as it does. To put things in perspective, I have a Future Impact which can do all kinds of other stuff, and tracks better but I think I prefer the sounds I can get out of the Squeezer, and the FI doesn't have anywhere near as strong an envelope filter or gated fuzz in its arsenal.
