Well, I picked up a H&K Grandmeister not too long ago. Very cool amp.
4xEL84's and 3x12AX7's Tube amp with built in digital effects. Reverb, Delay, Chorus, Flanger, Phaser, Tremolo.
Built in noise gate. Built in Redbox for direct recording. Built in attenuater to drop it from 36w to 1w.
4 Channels. Clean, Crunch, Lead, Ultra.
128 midi presets to save and recall your settings.
It like having my old Rack System (Rocktron Piranha, Intellifex, Peavey 50/50) in this compact little head.
And you can control the settings from your Ipad if you want. there's also a third party software for Android and Windows now.
Now, you'll also notice the Carvin amps. X100b iv and V3.
The V3 is midi. I can use my L6 HD500 or my Pod XTL for effects and midi control of the V3.
For the X100b, which is not midi, I bought a Voodoo Lab control switcher. This allows me to to control, via midi, the 2 channels, reverb, loop, and boost of the X100b with either the HD500 or XTL. Again using the L6 for effects and midi. allowing me to assign which ever head I'm using to the presets of which ever L6 unit I'm using.
In this pic I'm using the X100b, XTL and Voodoo Lab. The VL is the little unit with the 4 lights lit up on top of the X100b.
