Just received a 2 button footswitch for my ABM500. I didn't have a chance to try this before practice, and it wasn't what I expected. I wanted to use the valve drive and maybe sub harmonics. Neither switch is labeled on the pedal, it was a bit confusing.The rear panel has jacks for sub/valve and eq/shape. Should I have ordered another pedal for eq/shape? Is it practical to just reach over and use these manually? I don't think I use these presently, but you never know when you might. How are Ashdown users using the footswitches? Also, anyone care to share the settings they use. I just try and get a low punchy tone through a Berg Ht112. I could get a different cab and get lower, but this is easy on the old back. Thanks
