Individual controls for Gain, Bass, Mid, Treble, and Volume, allow for the first channel to be adjusted independently from the second. With only a little Gain added, the sound offers a lot of headroom and covers a lot of musical styles thanks to the very efficient EQ. With higher Gain settings the amp reacts strongly to the output of the pickup and can distort. In all other settings the amp remains highly dynamic and has enormous punch at all volumes.
The channel works very well with distortion pedals, overdrive pedals or modulation effects – expect high quality wicked sounds. To answer the question of the channel’s sound: rather American.
Just like in the clean Channel, there are individual knobs for Gain, Bass, Mid, Treble, and Volume. Additionally, there is the Gain switch which can add or subtract a Gain stage. With the Gain switch on LOW and Gain settings in the lower third, clean or slightly distorted sounds are possible, depending on the pickup. If you turn up the Gain, you’re rewarded with a full and rich rock sound. The sound is very straightforward and dynamic; chords ring out forever and playing with the Volume knob of your guitar is really fun! The channel reacts very well to the player and does not thin out any sounds.
With the Gain switch on HIGH you will be blown away. More Gain, a little more compression and with a more modern tuning, this channel will burn the house down with fat rhythms, screaming leads and razor-sharp staccatos! Always on point, even with a lot of Gain and Bass. Chords stay crystal clear—and with the Volume knob clean sounds are possible even with this setting. Thanks to the efficient EQ you will achieve a high-quality sound from ‘80s hair metal to modern core and djent.
The PurpleNightmare is equipped with a versatile section of power amps. After your sound has passed the preamp stage, it has a tube-buffered Effect Loop at its disposal. Like the T/S, the Loop can either be turned on permanently, activated by foot switch, or assigned to a channel or the second Master volume.
The second Master volume can be used by foot switch and enables you to boost the volume, e.g. for solos. The Sharp knob sets the high frequencies of the power amplifiers; the Rumble sets the low bass. With both knobs you can modify the sound even more and adapt it to various speakers and room situations. The sizzel-switch option will add some high frequ. "fizz" to your sound. The amp works with four 6L6 power amp tubes with a push-pull principle and accomplishes around 100 Watts. On the back there is a Bias test point and a knob for each of the two pairs of power tubes. The power tubes can be adjusted by any technician after changing – without removing the amp from the casing. Additionally, the two independent knobs enable you to use different tubes. Two 6L6 combined with two KT88 or two KT88 together with two KT66 – not a problem!
Creative at night?
Using a 100-watts tube amp at a neighbor-friendly volume can be a challenge: turning up the Master volume just a tiny bit and the walls start to shake. For this case, the PurpleNightmare offers a 2-Watt Switch. It switches the power amps completely off (including heating!) and gives you a 2 Watt Mosfet power amp—more than enough for creative nights or a simple practice session at home (at full volume your neighbors will still hear you).
Power amp tubes are wear parts and are getting more and more expensive, so why should you waste them on a simple practice at home? By switching off the power amps you will go easy on them. In this mode, the amp can also be used without speaker or load box.
The amp can be controlled without a footswitch. Channels can be switched on the front panel, Loop and T/S can be switched on/off or assigned to a channel on the back. All features can be operated by footswitch, including Channel switch, Master switch, Loop, T/S, and MUTE. Additionally, any of the features can be switched on externally. This way, a multi-FX processor with switching outputs can switch the channels of the amp or even the loop—a simple contact is sufficient. With the help of a Midi box the amp can be entirely remote controlled.
Thanks to the rotary switches Loop and T/S you can switch to many sounds without a lot of tap dancing on stage: you set the T/S to Channel 2, the Loop to Master 2. By switching the channel from Clean to Burn the T/S switches on automatically; by pressing Master 2 you activated your Loop with echo and reverb and get a little more volume for your solo.
Apart from the 5-Footswitch there will be one with only two knobs, to which you can assign features at will. If you only need the Channel switch and the second Master or the Mute on stage, then get the 2-Switch!
