Kool Amplification - Marvell Deluxe

Marvell Deluxe

The Marvell Deluxe is the culmination of 20 years of relentless tone chasing and high end tube amp design. The result is one of the most versatile, tonefull high end tube amplifier to date. 
Technically the Marvell Deluxe is three of Kool Amplification's most beloved masterpieces combined, all in one tiny, sturdy small box: 
Channel 1: Ace
Channel 2: Marvell
Channel 3: Dark Matter

 Channel 1: "68 Plexi Clean"

Imagine a super clean version of the orginal 68 plexi with a hint of TwinR. Huge, fat and open 3d tubemagic in action. A perfect platform for all pedals. Dial it all the way up and boost it with a clean boost pedal, and you're in 70's ACDC heaven. Milder setting with a strat and some fuzz or tubescreamer and you'll go from SRV to Hendrix.

Channel 2 "Classic Plexi / moderate crunch - Overdrive"

Technically this is a a '68 Plexi with a ''Jose Arredondo style'' tube driven pre-amp booster integrated in the circuit. The result is a ultra wide gain range, ranging from subtle 70's crunch to comtemporary overdrive. What makes this channel so special is the ultra tightness of the bass, alowing you to cut through any mix, literally endless sustain and gain, while retaining the fattest plexi tone imaginable. 

Channel 3 “Contemporary Plexi ultra overdrive”

Ultra high gain overdrive style version of the already quite hot rodded Marvell. (Dark Matter channel)

Loud & Louder Attenuator

The foot-switchable 'Loud & Louder Attenuator' alows you to attenuate and boost the overal power of the amp from 20 to 50 Watts. As it is footswitchable you can set ''Loud'' for rythem guitar and ''Louder for solo.

True bypass effects loop (foot-switchable) 
The effects loop is buffered by 12AU7 tube. Adding the 12AU7, for several reasons, is not the cheapest solution but the 12AU7 does this job best as it affects the original signal least. The effects loop’s volume knob enables you to amplify, attenuate or balance the signal. Last but not least: You can true-bypass the effects loop with the footswitch! Tech talk: True bypass is achieved by a double relay switch at the front- and back of the loop. When the loop is being bypassed the loop physically disappears from the signal path. 
A ''level knob'' is added to level, boost or attenuate the signal.
