Re: Get more punk rock chug out of Mesa Boogie DC2
These amps (and most older Mesas in general) are voiced for smooth midrange. And in a 112 2xEL84 combo, it's going to be hard to get the deep chug of a big bottle amp pushing a 412 cab.
Having the "right" tubes can help. I'd probably stick with the Mesa EL84s versus the "softer" JJs that I like. I might try one or more of the "harder" 12AX7s in the preamp, like the Mesa, Tung-Sol or the E-H.
Speaker might help, and rather than replace the original, you might want to try finding a Mesa 112 Thiele cab to put under your combo. It will definitely add value to your rig, and add back a lot of low-end punch and thump. The best speaker is the EVM, but the Mesa Black Shadow C90 is good too.
I have a Celestion V30 in my DC-3, and I love it. That would be my recommendation for a replacement speaker in your amp, but I'm sure you'll get many other recommendations from other members.
Resist the temptation to place your amp on a stand or chair. You'll get the best bass coupling with the amp in the floor.
Be sure to download the DC-2s Owner's Manual from the Mesa website, and read it until you thoroughly understand how your controls work. Mesas are not your run of the mill amps, and there are some cool features in the tone controls, especially the midrange control.
A graphic EQ can help, BUT...you will need to very careful about not adding too much bass with the EQ...you can blow the speaker. Either the MXR 10-BAND or the BOSS GE-7 or the MESA 5-band will work, but I would suggest experimenting before you buy, if you can. They are very different units. You may also need to try it before the amp, and in the Effects Loop to see where it works best. The other amps in the DC Series have the GEQ built-in. It is a great feature.
I don't have any pedal recommendations; the pedal junkies on the board know far better than I. But, I would certainly look for one with B-M-T tone controls.
Good luck with your amp. It is a budget amp from Mesa, but it is solidly built and should give you years of service. With the Thiele it will sound like a much bigger amp, and even by itself, it can hang with a drummer in small club.
And READ THE MANUAL!
