We like our circuits a little “crazy” being far from just another clone. The first CTC amp model is exactly that: a crazy different approach. This is not a duplicate of any of the classic tube amp designs. It’s an amp consisting of an all EL84 signal path, from preamp all the way to power amp. 
As a pedal company we designed Paradox to work great with pedals adding the character and smooth, natural compression of the EL84 tube. 
The normal input will give you loads of clean headroom all the way. While the total volume of this input is not ear piercing making it perfect for studio or small club use, the headroom is virtually unlimited. It will be really hard to overdrive this channel without the use of an overdrive/boost pedal. To achieve that we have carefully chosen an overwound output transformer made by Magnetic Components, USA and fine tuned the all EL84 circuit for thick clean tones even at low volume. 
Plug into the “more” channel if you are looking for 100% EL84 overdrive/ distortion. It starts with a jangly clean transforming into a biting crunch up to verge of distortion. Due to the nature of the power tube, feedback, sustain and complex harmonics come effortless in this channel.
