Only used it on one gig, so, totally in the honeymoon period, and I've been changing my rig once every 3-4 months for the last two years, so who knows how long this will be around! My setup: PRS IRW Custom 24, Sennheiser G2 wireless, Dunlop crybaby wah modded by Area 51 tube audio designs, Korg DT-10 tuner, into amp, into Avatar 4x12 with V30's on top and G12H30's on the bottom. I picked up an EL-34 Rivera Knucklehead reverb from a TGP/BaM member, complete with Headmaster. I had already had a 6L6 Knucklehead II last year around this time, but that was before I found the PEDALSNAKE , and I grew very tired of all the cables I needed for my setup, and it was only the 2-channel version, so I sold the Rivera and went to a Line 6 HD-147 that I used for about 5 months. My biggest problem with any gear is this: I've used midi rack gear from 1989-2002, so, I'm used to stepping on one switch and going from, say, clean with chorus to a solo tone with delay, and having multiple tones on tap. Doing that with tube amps is much more complicated. First, I haven't found (until now) 1 tube amp that did everything tone-wise that I wanted it to do, much less that was midi-capable and came with it's own powered midi controller. I simply need more than 2-3 different tones (in a cover band), and I hate tap dancing to get them. The other problem I've discovered is that I love tubes. None of my other past gear has sounded/felt like tube amps, they've all been simulations, but not the real thing. First, I haven't heard every amp made, but I definitely haven't heard many channel-switching amps that can beat a Rivera clean. I had been using a Dual Rec for the last few months, and it's like night and day. I was actually trying NOT to use the clean on the Dual Rec. The Rivera is a thing of beauty, and while the band does Godsmack, we also do some dance and funk, and I like a nice, pristine, bold clean sound for funk and dance music. The clean has a bass/mid/treble setup, with pull options for each knob. I found my clean tone within about a minute, but I'm familiar with Riveras' EQ and tone controls at this point. Second, I like the sound of an old Marshall for the classic rock stuff we do, think Angus Young with a tad bit more gain available. The Rivera's second channel is pretty good at this sort of thing, and also has a push-pot for additional gain. So I've got the hot-rodded Marshall thing going and use the volume knob to taste on certain songs. I also use this tone with the gain boost on for my leads, it's perfect. Third, the scooped, dropped-D tones. With my old Knucklehead II, I had to set a "tweener" tone, that is, a tone that was inbetween that classic rock tone and nu-metal tone, and live with it. While this can be done, I like the luxury of having the 3rd channel, I set that for the nu-metal stuff, lots of gain (too much actually!) and real aggressive. One thing I thought would be limiting is the dirty channels share an EQ, which I usually hate, but when you switch around the different channels and boosts, the EQ shape changes, and it seems I have it set so there's not a bad tone to be had, I like them all. Put on top of that the ability to switch most of the amp's functions via it's included midi controller (the Headmaster), and I may just have found the perfect amp for me. You can set a patch with the FX loop activated, or not, or with a boost on, or off, or with reverb on or off, it's great. The only thing you cannot do is switch the push/pulls in and out, once a pull switch is pulled out, it stays that way. I used a delay pedal on the last gig, and I kind of like hearing that in my in-ears, I don't think the audience hears it, and at this point, I could just leave it home and probably not care, but it's nice to be able to footswitch the FX in and out. There are companies like axxess-electronics that make it possible to control amps via midi, so I could have been doing this in the past, but the problem was, I never found an amp that was flexible enough for me to do what I want to do with no compromises, in time, we will see if this is it. I don't have time on stage to fiddle with knobs to get different tones, if it isn't available by footswitch, it's useless to me. If this amp isn't "the one" in a few months, the only other amps with this much flexibility I could see using in my current band would be either Engl stuff or a Hughes and Kettner Triamp MKII, but my Knucklehead costs much less.
