Well, this is a question asked many times, and well, I personally think that no mod will be done to the herbert ever
... but... well, if you ask me, the mod I'd do is short and easy:
1. +/- midi switchable... and off course, a independent GAIN knob for - mode.. (one gain for each mode, + and -), and keep the bass/mid/treeble the same for both modes... (Off course, the PERFECT would be a completly independent channel for - mode, but that would make a pure 4 channel amp.. which, if you ask me, would be absolutly PERFECT and WHAT I'd NEED SO BADLY... Ok, I know there is a VH4, but it's not the same... I personally prefer the Herbert, at least for me and my style. And well, the minus mode midi switcable woul dbe simply awesome (but again, it would have to has a own GAIN knob, if not, it wouldn't be that great.
Apart of that, the herbert is simply PERFECT... !!! How I wish I could have that !!!
Peter, is there any possibility in this world to "improve" this in a future ??? or there will be no way ???
Again, HERBERT IS THE BOMB !!! (but it really need to offer the possibility to use all its features in deep... Dont tell me it's not a f@*! that we are not able to use the +/- ??? Shit, I must decide... will I use + or - ... because I cant use both on stage !!! aghrrrrrrrrrrrrr and that really KILLS ME !!!
