It's the Bass-Treble boost one. Has anyone tried it?
Is there any important difference in the eq, tone etc?
I don't know if you guys have needed a fast tonal change from one song to another without change the amp settings. I did many times. For example after Smoke on the Water comes Enter Sandman or even worse Sad but True. I thought of it many times and I think this small unit could help.
What do you think?
