Dialing in Channel 2 (Crunch)
You’ll note the Dual Volume/Gain design of Channel 2. For the moment, let’s forget about
Volume/Gain B. Set them to 0 and forget them.
You’re crunch channel is also capable of producing a wide range of tones as well. Most
important, the sweep of the gain knob will change more than just the gain. The most
important feature is that as you bring the gain below 5, the amp will brighten. So, if you’re
looking for punchier, cleaner and brighter tones, keep the gain down. If you want to make it
heavier, bring the gain up above 5. YOU SHOULD NOT LIKELY EVER NEED TO BRING
THE GAIN ABOVE 7 OR 8. As noted, this amp is capable of producing more gain than
tubes can handle (or than you’ll need). Bringing gain levels to or above 10 can exceed the
tube’s capabilities depending on the circumstances, which is why excessive gain will
not likely produce a desirable tonal result.
Start with your Channel 2 controls all at 5 with the bass on 3 or 4. Try, first, bringing up the
Presence control and sweeping that knob. Once you get your presence dialed in, then
sweep your midrange (see the previous section on the mid-range control. Those controls will
tone alter the amp more than any others on this channel. Here’s a few sample settings to
give you some idea of what you can do:
