The CPC-80T is our take on the Fender 5F8A High Powered Twin that capture the sound but with small circuit improvements that make the amp more reliable and more toneful.  Properly setup the Higher Power Twin is one of the greatest amps ever created.  The cleans are amazing with rich mid-range character and powerful low end. As the amp is turned up it gets thick to die for overdrive. Every note is thunderous and touch sensitive.  You don't just play this one you feel it.  It takes pedals like a dream!

Customer Comments:

“ Hi Carl,

As I said before and I will say it again, you are a wizard in my eyes but most importantly my EARS! The amp arrived the other day and every chance I get I mess around with it. The tones out of this thing are amazing. Very tight when set clean and when cranked and overdriven, its very hard to put any kind of pedal in front of it even if its just boost because it sounds so natural and just raw! I've watched interviews on Joe Bonamassa and how talks about high powered twins. He uses terms and phrases like "the notes bloom" and "squish". I couldn’t really grasp the concept from just listening to a youtube video. But once I played the tumbling dice, everything clicked in my head and I could not only hear what Joe was talking about but I could also FEEL it. Its true what you say in your description of this model. This is an amp that you feel when you play it! I am so happy I ordered it with the alnico speakers. A whole different world compared to a ceramic speaker. A little brighter but very tight and clear. I was pretty hesistant at first only because this is a whole new amp experience for me between the speaker choice and the power tubes being 5881's as opposed to today's standards of either 6L6's or EL84's/34's. But I was looking for the most "vintage" and "period correct tone" I could possibly get. Especially when looking into buying a tweed amp... the tones of a tweed twin are not something to take lightly or cut corners on. Not to mention, with your patience and guidance between answering every single question of mine and never skipping a beat when it comes to replying to the abundance of emails, I still would probably be looking into something that would have disappointed me down the line. Again I am beyond thankful and appreciative of your help and honored to have spoken with you on the topic of tweed amps in general. To be quite frank, this is actually one of the brighter amps I've played in my time. Yet the midrange still manages to cut through and makes sure everyone who's listening knows that its there. I have been running my E.Q. pretty much slightly boosted. The only thing that remains flat is the treble knob. Other than that, the bass, mids, and presence knobs are all at about 8.5. After that, I adjust both volumes from there to taste. In conclusion, your tumbling dice model is an absolute gem and I anticipate taking this piece to the grave with me. Thank you again!”



The amp arrived on Saturday, December 29th and it sounds great!

NO ICE PICK TONE!!!! Thank God.

I like very much that I can get breakup at around 5 instead of my friends Hi Powered Twin at 7 or 8. No problem with the neighbors so far.

Again thanks for a great amp!

All the best,
