Kool & Elfring Black Rose Head
BLACK ROSE MKII
Honoring the legendary Roisin Dubh (BLACK ROSE)
Channel 1 (2 modes selectable by pushpull gainpot)
Ch1-mode 1: 'Clean'
The gain setting starts at splendidly sparkling and dynamically clean. Beyond one o’clock the clean morphs into a clean sound with sweetly organic edge of breakup. Around three o’clockvery gradually the sound changes into a sweet and subtle 3d-crunch. The sounds of ch1-Tweed-mode are best described as dynamic, three-dimensional, open and sparkling. It’s warm yet with good definition. This mode reacts perfectly to fuzz and boost pedals plugged into the front.
Ch1-mode 2: 'Super lead'
When you pull the 'push-pull-gain-pot' of channel 1, several parameters in the circuit are being altered dramatically, changing channel 1 into a super flexible, all-plexi-style circuit. Like the original plexi, the overall sound is three-dimensional and open sounding with super tight bass response and very pronounced mids. When the gain-pot is turned up, it is easy to ‘clean up’ with the volume-control-pot on your guitar, just like the original plexi's.
Channel 2 'BLACK ROSE'
The 'crunch channel’ begins where channel 1 (clean voicing) stops but with more compression. Before nine o’clock you’ll find some incredibly cool crunchy 60’s sounds. Turning up the gain knob a little further the sound will effortlessly change into an amazing compressed 80’s style crunch. When you turn beyond two o’clock you’ll be entering ‘overdrive territory’. The overdrive sounds are harmonically rich full and fat yet tasteful, organical and musical. The sound of channel 2 is characterized by natural compression, super tight bass (no mud!), tasty harmonics and unparalleled sustain. Whatever gain setting you'll choose, it will always give a killer sound that cuts through the mix with ease. Channel 2 responds excellent to the volume-pot of your guitar.
SVC Volume Boost (NEW!)
The foot-switchable SVC Volume Boost enables you to soloboost channel 1 and channel 2 with adjustable volume control. In fact the SVC Volume Boost is an extra SVC Volume knob, with the exact same function as the original SVC volume knob. Turn this boost knob a little further than the SVC knob, engage the boost-button on your footswitch and your solo's will be boosted unlike you've ever experienced. It's like having a crew member turnig up your SVC volume whenever you start soloing, absolute guitarplayer luxury!
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.
SVC -Seamless Volume Control- (Tube amp volume under control !)
As both channels have individual gain and master volume controls, it’s easy to find your sweet spot on each channel. In the power section you’ll find an extra ‘total’ volume control which enables you to balance both channels volume levels, perfect for playing 'live'. But there is another amazing and unique feature called SVC (Seamless Volume Control). The power section ‘total’ volume control is capable of producing 0,1 Watt bedroom levels yet retaining great tone. So from now on the power-soak is a thing of the past!
2 fully independent channels / 3 modes
Channel 1-Mode 1 = 'Clean', Channel 1-Mode 2 = 'Super Lead'
