The Slammi is able to add one interval, either up or down in pitch, to the original signal. The original signal has a volume/mix control so it can be removed. The Plus is able to add one interval above and one below the original signal.
I didn’t go with the Plus because the NS pedals are “built like tanks.” However they all require power, even the EXP, Pan, and Volume.
Thanks iOS. Yes, I didn’t realize from the on-line pics but the Slammi Plus is entirely made of plastic! And no activation (on/off) light so you have to guess on stage if its on or not. That’s pretty bad. It just oozes cheap low quality and I would be very hesitant to use it on stage anyway. It appears really fragile, maybe good for bedroom use only. Doesn’t really matter how good a pedal sounds if it isn’t designed to be durable for working musician use. Very disappointed in EHX for the very cheap build quality of the Slammi Plus – it really is just a toy from that perspective. I will be passing on the Pus pedal and maybe seek out the original if I can find a good deal on one now that the’re discontinued.
Thanks so much! Really appreciated.
