The MIDI board FSM 432 MK III does far more than simply select presets, like most MIDI controllers. The stomp-box mode also allows you to switch channels directly, and to activate modulation effects, delay and boost independently. It also offers two 1/4" jack inputs to connect expression pedals or single footswitches. Both inputs are freely assignable to remote control any pot and switch of the H&K GrandMeister 36 in real time. Though the FSM 432 MK III is optimized for use with the GrandMeister, it can also be used with the superb Switchblade, CoreBlade and TubeMeister 36 amp offerings from H&K.

The most eye-catching alteration from the MK II is the new ergonomic shape of the die-cast case. To better work with the radius of your foot's motion, the FSM-432 MK III is slightly bent, so distance between the now-staggered buttons has been extended to avoid accidental operating errors.

  • Compatible with GrandMeister, SwitchBlade, CoreBlade and TubeMeister amp models
  • Can be used in conjunction with an expression pedal
  • Curved body shape for improved ergonomics
  • 4 buttons for channel/preset selection; 2 buttons to cycle presets; 1 to set tap tempo
  • Rugged, heavy-duty construction

Comments about Hughes & Kettner FSM 432 MK III MIDI Footswitch Controller for TubeMeister and GrandMeister:

I bought my Coreblade (from 123) without a footswitch. It's a necessity to store settings to a preset other than the one you're currently on. The manual talks about it being able to be used with other MIDI footswitches, but through trial and error, you have to put things in a specific order. There is NO ONE to talk to about this. No info in the forum, and unless you want to pony up for a call to Germany, you won't get their American distributor, Yorkville. 5 calls have gone unreturned. Also, bc the manual is for Coreblade AND TubeMeister, it's not clear as to which MIDI cc's work for Coreblade. Again... trial and error. I will tell you that using a pedal to sending cc values on either cc 126 or 127 (can't remember) results in a factory reset!!!
Certainly not Music123's fault, but there's just no support for H & K in the US or Canada right now. I'm using it only to move and store patches only - for gigs, I just send PC #'s through my Ground Control Pro - easy enough...
