Like a British classic but with more warmth, muscle, and richer harmonics.

The Chadwick is a "fully Kranked" version of the classic British tube amp ala JMP/AC-30, but with more tone and more muscle. This baby pumps out 50W of classic tube tone laced with incredible harmonic overtones and warmth.

The Clean channel is big and fat with clarity and power and features both Volume and Gain controls so you can dial up anything from perfectly clean to a sparkly rhythm.

The Drive channel features 3 gain stages (variable Gain, switchable Drive, and Volume) with a very trick Envelope circuit that creates a punchy overdrive similar to output tube distortion when turned up and an icy tight brittle sound when turned down. Both channels feature very smooth Bass, Mid, and Treble EQ controls that enhance your sound rather than change it. Any player from classic rock to hard country will love this amp. The Chadwick is a great match for the Revolution 4 X 12 cabinet with four Eminence V12 legend speakers.

The Chadwick in detail:

Gain—This controls the amount of distortion or overdrive generated at the front end of the preamp section.

Drive—This adds gain in the middle of the preamp for more distortion and overdrive. Pushing the Drive switch in increases the gain in the circuit.

Envelope—This controls the amount of gain in the last stage of the preamp. Turned down, the envelope will sound cool and bright. Increasing the Envelope will increase sustain and make the amp sound a bit softer. It's best to start in the middle and check out both directions with this control. Note that if either the Gain or the Envelope is turned all the way down the amp will make no sound.

Shift—This switches the tone of the Drive channel between one of two preset values. In the "out" or "off" position the circuit flows normally through the EQ section. Pushed in and activated, Shift allows more mids and lows through the circuit and makes the tone controls slightly less active. Simply put the Shift control switches between Classic Tube and a Modified Tube amp. Krank thought both sounded great and so gives you both options to let you choose what suits your style best.

      Comments about Krank Chadwick 2-Channel Amp:

      I was surprised at how many good tones I was able to pull from this amp. I have a paul reed smith ce22 that sings through this amp and it also plays well with my fender strat. The clean channel on this amp is a huge shining point. You can get some nice glassy cleans and with a twist of the gain knob it will go bluesy to a nice hard rock crunch. The distortion channel will have a nice breakup with the drive off and the shift off. When you kick them both on it can get some really nice hard rock tones. There is also an envelope filter that will go from vox to modded marshall territory. The key is to play with the drive, shift, and envelope settings to get your tone. There's alot of nice tones available here. I can honestly say this amp outshines my bogner.

      Comments about Krank Chadwick 2-Channel Amp:

      I get GREAT tones from this amp! The gain/crunch channels is great and is where this amp lives. More gain than the name "chadwick" implies. i think that is where this amp falls short...it's name...but not in the sound dept. It's a shame...these are now discontinued. Built really well too. I recommend this amp any day to anyone ( well maybe not a jazz guy or a hard core blues guy. )

      Comments about Krank Chadwick 2-Channel Amp:

      couldn't believe this thing was a tube amp when i first played it. no matter where you position the gain or envelope, the thing is full of gain, but not a nice gain. like a swarm of bees. this amp is extremely comparable to a marshall mg100. and they spell "crank" wrong which is lame.
