I really wanted to like this but I'm afraid it's going back.
sioux33 04.10.2024
I'm sadly in a position of having to return this and I'll explain. I really find it difficult to be in a position to criticize this pedal when everyone is raving about it, but hey I'll go on anyway.

First the positives. The pedal in terms of build quality is a tank. Like any other CTC pedal, and I have been through a few, there is no expense spared in the construction, finishing, and selection of components. The buffer on the Klon side is amazing, one of the top if not the best buffer I've ever used, and the Klon side sounds great on the stock setting.

Nevertheless I found some significant (for me) weaknesses when using it.

a) For me the Dumble side was a major let down. I read and watched raving reviews about this how glassy and dynamic it is etc. To be honest, my Laney L5 studio in the Low input, bright switch on, and EQ B-3 M-3 Tr-7, Tone-8 sounds leaps and bounds better with my Strat. In fact, if anything, I felt the pedal killed the harmonics and the glassiness of my amp considerably at any gain setting/EQ.

b) The amp side has 'enormous amounts of volume' as also stated by CTC. My opinion is that this amount of volume has no practical application as this is a pedal more likely to be set and forget rather than fiddle with it all the time. You can switch between the amp models with a FS, but only with the same settings, therefore you can't use the Dumble side as both an OD and a clean boost in one session which makes the feature pointless IMO. Unity, with the gain set at 2 o'clock is around 8 o'clock and the enormous amount of boost the pedal can provide makes it very difficult and fiddly to not only find unity, but also pinpoint a desired boost setting. Note I have the same issue in the Hi-Power Colorsound side, but I had no difficulty getting great tones there. Why there is so much volume boost on these pedals is beyond me.

c) The germanium transistors compared to the stock diodes do change the sound, particularly taking away the Klon muddiness thus making it more clear with a more crisp and aggressive attack. Both settings sound great, but IMO you wouldn't buy this pedal for the Klon side to NOT sound like a Klon. So the inclusion of this option makes no sense to me after hearing it. These transistors would probably make a better application than this.

So overall, I find that the Unobtanium Raw is an expensive pedal for what it does, given that I found it very difficult to get value and new sounds out of. I have not tried the original version, but I'm sad to say this pedal felt like a gimmick to me, more like bunching together a few hyped things than trying to make something meaningful, and I did not expect this from CTC.

I'll say I have a few of their pedals currently on my board, the TI:ME delay, the Super Conductor, and the Hi-Power and they will never leave my pedalboard especially the latter 2. The Hi-Power, which is a similar concept, makes much more sense as a pedal to me and is much easier to configure and get great sounds out of despite having a more complex EQ interface.

Can't find no fault with this pedal!
Georgek2 10.09.2024
I really wanted to look for something negative to say but in all honesty this is an absolute amazing pedal!
Sensational tones and options to be found here and from subtle od to heavy crunch this pedal covers a lot of sonic ground in a way that just feels organic.
If i had to critisise something would be for this price they could maybe include the footswitch...

Ein Pedal der Extraklasse !
blue element 25.08.2024
Ich besitze zwar schon zwei Pedale mit "Dumble-like" Sounds, aber dieses Unoptanium hat mich einfach neugierig gemacht. Da kam das neue Unoptanium Raw gerade recht. Die rechte Seite mit den Klon-Sounds bietet von Boost-bis kernigen Rockklängen schon eine gelungene Palette an Grundsounds mit der man von gepflegten Blues bis klassischen Rock schon alles abdecken kann. Der Schalter mit den man von "Stock" auf "OC45" wählen kann, wirkt aber erst dann wenn die Vol. und Gain-Settings lauter eingestellt sind, es bleibt aber immer noch eher subtil. Die Klangqualität ist aber stets vom Feinsten und der Grundklang wird nicht unnötig verbogen.
Nun zur linken Seite: der Dumblesound ist heutzutage auch kein großes Geheimnis mehr und es gibt schon genug Kopien, egal ob Amp's oder Pedale die sehr gut klingen. Ich besitze sowohl einen Klon von Ceriatone Centura und ein original Zen Drive, beides sehr gute Derivate. Nun zum Unoptanium: der Kippschalter mit der Option zwischen der "SSS" bzw. "ODS" Variante, ist ein sehr gelungenes Gimmick. Die SSS Position bringt einen schlankeren/klaren Ton zum Besten mit enormer Durchsetzung. Die ODS Variante bringt erwartungsgemäß genau diesen Klang zum Besten mit den cremigen Mitten wofür man "Dumble" in Verbindung bringt. Klanglich auch vom Feinsten ! Der Emphasis Regler ist insofern nützlich, da man damit speziell Humbucker-Gitarren etwas straffer formen kann, aber auch hier eher subtil, was ich persönlich aber als Vorteil sehe, weil der Grundsound erhalten bleibt. Was mich sehr positiv überrascht hat, speziell mit Singlecoilgitarren, wenn man den linken Klon-Kanal in Boosteinstellung hat (Gain max. auf 10h) und zum ODS-Kanal dazuschaltet, hat man einen exzellenten Solosound mit angenehmen Höhen und einer Smoothness die ich so, mit z.B. einer Strat, selten gehört habe. Einfach Klasse !!!
Fazit: der Preis dieses Pedals mag vorerst etwas abschreckend sein, aber man sollte nicht vergessen, hier hat man eigentlich zwei Pedale mit wirklich exzellenten Sounds von Bester Qualität und mit den Extras wie Einschleifweg für FX Pedale und XT Fußschaltererweiterung, relativiert sich der Preis allemal.
Klare Kaufempfehlung !

Unobtanium Raw
andrewbb 13.08.2024
I already have some drive pedals that I really like and this Unobtanium Raw tempted me so much that I had to buy it. :) I made a good choice because it has a very good sound, looks good and is built the way a quality pedal should be built. It's not cheap, but the value of the pedal is justified by the quality. That's it!
Thanks to Crazy Tube Circuits and thanks to Thomann! ;)
