Zoom B1 Four (SOLD)
Update: Now sold
Zoom's newest bass pedal - you can read about it on this thread: https://www.basschat.co.uk/topic/337340-zoom-b1-four/
I bought it new in May but have decided to stick with my MS-60B - which isn't the latest, and has fewer functions, but it is smaller.
£50 collected from London W4 (Gunnersbury) or N12 (Woodside Park), or add £5 for UK postage.
No batteries included. Very small light scuff on the base where velcro was attached.
I also still own a B1on, and the B1 Four interface is easier to use and with a clearer display and lights. The B1on is an older chipset, I think.
I've not used a B3n but I think it and the B1 Four share the most-recent processor. The B3n has more buttons but it is larger.
