My MS-50G was finally delivered this morning. No box, manual or USB cable, but it looks like its in near perfect condition and it was only £50 so I'm happy.
I'm only going to use the pedal with guitar as I have a zoom B3 for bass so I won't bother with 'jailbreaking' the MS-50G to load MS-60B fx on. It had the v3.0 firmware when it came so I've flashed it to v3.1 and used the effect manager software to add some additional fx.
I just had a noodle with my banana yellow bullet mustang into my vox valvetronic amp via the MS-50G and some of the effects sound very impressive. The reverbs in particular are great
How to use the knobs and buttons is still a bit of a mystery to me so I've put the manual and effects list pdfs on my iPad so I can learn how to use it.
