Very sturdy and well made heavyweight footswitch for most H&K amps. Works well in many different models, but I don?t know if you can use in parallel with other brands? My advice is to use only the standard and recommended footswitches so you won?t damage anything.
I like the 2nd button with 2nd channel for the boost, I wish they had made the boost also for the 1st channel as Blackstar did in HT20...
