It's made in two separate parts: the blow reedplate and comb are fixed, while the draw reedplate can slide left and right. The two halves of the harp are held together with magnets, which hold them in the neutral position for normal play. But when you want the extra bend notes, you just slide the draw reedplate a few millimetres to left or right with a small adjustment of your grip. When you release your grip the drawplate snaps back to the standard home position.
Slide to the right, and hey presto: you can bend the lower blow notes! 2, 5, 6 and 7 blow are suddenly juicily bendable. Slide to the left, and now you can bend your high draw notes! 7, 8 and 10 draw now bend like 3, 4 and 6 draw. In fact, you can play the top octave in exactly the same way as the middle octave. Just transfer your favourite middle-octave licks up there with identical bends and breathing patterns - so easy, and so expressive! Release your grip and the magnets snap the draw plate back to the middle position, for normal harp play with overblows and all the stuff you're used to.
I released the first SlipSlider in April 2018. The Mk1 was a revolutionary harp that proved the principle and worked well - but it was very complicated to make with many bespoke parts, and therefore quite expensive. It's now been discontinued; I released the first SlipSlider in April 2018. The Mk1 was a revolutionary harp that proved the principle and worked well - but it was very complicated to make with many bespoke parts, and therefore quite expensive. The Mk1 SlipSlider has now been discontinued - but if you have time check it out, it's an interesting harp! The current model is the Mk2, made from the Hohner Special 20. It's easier to play, simpler to make, plus has more bends and a lower price!
" The harmonica plays like a dream, I was a bit concerned about the air tightness when I first see the concept, but in action, I can overblow 456 and overdraw 789 out of the box, 10 is a bit squealing but I think that's just my technique. This is WAY better than the OOTB crossovers I've had in the past, so the air tightness is definitely not an issue.
In terms of the notes, from my little experience with it, I can now play the b3 in the lower octave which I wasn't able to get with OB, and I can get the same juicy bending trill between the major 7 and root as the PowerBender running in the middle octave when playing 2nd, much stronger than using OB, and much more musical and tonally pleasant.
It is totally a game changer for sure. "

" I purchased a SlipSlider Crossover in G a bit ago and have been digging it... Took a bit of time to figure out a method to prevent slipping fingers but in the end I came up with a nice grip system using a few brass finishing washers and a spot of hot glue; it works well and looks great. ... I really appreciate your ingenuity! "

" I finally put my SlipSlider together. This is fun. I haven't done much with it yet, just noodled around, and haven't decided yet how I'm going to do the grip modifications, if any. With Thunderbird covers it does pretty well, maybe just a small dab or two of clear E6000 glue on each side will do the trick. In C having the blowbent Eb and Ab available is going to be nice. The ease of disassembly for cleaning and adjusting alone is a great plus. If it works as well in the Lucky 13 regular breath direction models my other harmonicas are going to get dusty. "
