Played two gigs this weekend with my new Two Rock Opal. For those who may be interested, I'll share some musings: The amp has a very sturdy tone and response. It is very responsive and quick. My other main gigging amp (Savage Rohr 15) is cathode biased, tube-rectified and EL84 powered. It has a super thick, spongy sound with plenty of sag. The Two rock is an entirely different beast. It is more open and compresses much less. The two-rock has a very bouncy, energetic feel. While the Savage is way-fat and juicy, the Two-Rock is punchy and muscular. I like the gain on the clean channel up fairly far. With the whole band, I enjoy the fluidity that some fur adds to the tone. With the clean channel gain at 2-3 o'clock, I could have the gain on the lead channel fairly low (about 10 o'clock) and get a nice OD tone. I was getting more satisfying tones with single coils than with humbuckers. I think I need some more experience to get it dialed in appropriatly for HBs. The footswitch has two buttons: one for channel switching and one that bypasses the tone stack giving more gain. This is very useful. You can get 4 levels of gain with this set up: clean channel, clean channel bypass, lead channel, lead bypass. I used them all in conjunction with the guitar's volume knob to get a wide spectrum of gain settings. One of the greatest tones I got from the amp was to dime the clean channel gain and open the master to about 11 o'clock. This makes for a fabulous lead tone - you have tons of sustain, but it doesn't sound "distorted" and there is little compression. However, I did not use this on the gig as this is not quite the gain structure I want as I run through the setlist. Also - it is very LOUD like this. The mid boost switch is very potent. Engage it and there is a LOT more body to the tone. I had it off most of the time tonight because it seemed to mesh with the total band sound better. Now, I do have a Radial Headbone. This device allows you to run two amps thru the same speaker cab. I used this on friday to run the Two-Rock and Savage together thru the Savage's speaker. The results weren't great because the Two-Rock doesn't sound nice thru the G12H30 in the Savage cabinet. I have yet to try out all my combinations of speakers and cabs to see if there is one that works equally well for both amps. If I find it, I'll use both amps in my live rig and have all bases covered! Lookout!! OK, enough show and tell for now. It's 2:40 am and I still got my giggin' duds on! Time for bed!
